Overview
PureView Instruments comprise a family of Pulser-Receivers that are USB controlled and powered. The
various PureView models span a broad range of operating frequencies that enable a correspondingly broad
range of ultrasound system applications. User control of these instruments is achieved through commands
sent from a computer to the instrument via the USB interface. The JSR .Net Control Panel Software, a
Windows-based software application, provides such control, and programming information supplied with the
Software Developers Kit (SDK) and Programmer’s Manual allows a user to develop custom software programs
for controlling PureView instruments.
All PureView models are designed to be physically interchangeable which allows users to rapidly alter their
system configuration by interchanging models. PureView is an excellent choice for ultrasonic system
applications such as flaw detection, quality assurance, material characterization and transducer testing. The
PureView instrument enclosure is water resistant although care should be taken to keep the instrument dry.
Connections are easily made to PureView hardware by attaching coaxial cables to PureView’s four female SMA
interface connectors, and PureView Pulser-Receivers synchronize with other system hardware by producing or
accepting trigger pulses on the PureView Trig / Sync connector.
PureView instruments receive power through the USB interface. PureView is thus ideal for use in PC-based
ultrasonic testing and inspection systems, and its small size and relatively low power consumption enable
systems to be implemented using portable computers. PureView can be combined with A/D Boards or other
signal detection and processing instrumentation to give system integrators the flexibility to optimize system
cost and performance.
Theory of Operation
Communication with a PureView Pulser-Receiver provides a user with control over the receiver input signal
selection (T/R or Through), the receiver gain, the low-pass and high pass filter values, the pulser repetition
frequency (PRF), the transducer damping, and the enable/disable control of the pulser power supply.
PureView Instrument Functional Blocks
A PureView Pulser-Receiver is composed of the functional blocks shown in the following System Block
Diagram.

Control Logic and USB Interface
The USB interface and associated control logic provides control of a PureView instrument through software
resident on a host computer. A USB interface cable is supplied with the instrument.
Pulser (Energy and Damping)
The pulser generates a transducer-excitation pulse upon receipt of a trigger signal from a selected source,
either internal or external. The Pulser energy and damping controls provide control of pulse parameters such
as pulse duration, pulse energy and pulse amplitude. Note that a change to either the Energy or the Damping
value will affect all three pulse parameters.
The pulser produces constant-amplitude pulses over the specified range of pulse repetition frequency. The JSR
.Net Control Panel software and SDK software provide “power limit status” indications to warn a user when
PureView might be functioning beyond the specified range of pulser operation, i.e. at too high a Pulse
Repetition Frequency (PRF) which may result in reduced-amplitude of the transducer-excitation pulses.
Pulser Voltage
The pulser voltage supply provides power to the PureView pulser circuitry. The pulser voltage may be enabled
or disabled which allows a user to assess signals that are present in a test system with and also without
generating a transducer excitation pulse on the T/R connector. This can be useful for test system debugging.

PureView™ Pulser-Receiver Operator Manual
Page 11 Imaginant Inc.
T/R and Through Select
Selecting the “T/R” mode (also referred to as “Echo” mode) connects the T/R connector to the Receiver input.
This configures the instrument for performing Transmit/Receive measurements with a single transducer.
Selecting the “Through” mode connects the Through connector to the Receiver input. This configures the
instrument for performing Through measurements using a transmit transducer and a separate receiving
transducer.
Amplifier/Attenuator
This functional block provides control over the PureView receiver’s gain. The receiver gain can be set in 0.5dB
increments across the gain range of -11.5dB to +70db.
Low Pass Filters
The low-pass filter enables a user to reduce the bandwidth of the PureView receiver to improve the signal to
noise ratio or to eliminate out-of-band signal content for applications that do not require the full receiver
bandwidth. Two user-selectable low-pass filter values are available.
High Pass Filters
The high-pass filter enables a user to eliminate low frequency energy from the PureView receiver signal, and
also to improve the rate at which the receiver output returns to its baseline level after the Pulser excites the
transducer. Two user-selectable high pass filter values are available.

PureView™ Pulser-Receiver Operator Manual
Page 12 Imaginant Inc.
PureView Enclosure, Interface Connectors, and Status Indicators
PureView Pulser-Receivers have four coaxial SMA connectors, a mini USB connector, and LED status indicators.
PureView T/R and Through Connectors
As shown in the image below, all PureView models have two coaxial SMA connectors (labeled T/R and
Through) for interfacing with one or two ultrasonic transducers.
In the Transmit-Receive T/R (Pulse-Echo) mode of operation, a single transducer is connected to the T/R
coaxial connector, preferably via a very short length of coaxial cable. The PureView pulser generates a
transducer-excitation pulse on the T/R connector to excite the transducer. The transducer converts energy
from the electrical excitation pulse into an ultrasonic pulse that is propagated into a test material. Ultrasonic
return signals (echoes) that are reflected from within the test material are received by the transducer and are
presented to the receiver input via the T/R connector for amplification and filtering.
In the Through mode of operation, a transmitting transducer is connected to the T/R connector, and a second
receiving transducer is connected to the Through connector. This second transducer detects signals that
have propagated to it from the T/R transducer, usually after passing through a test material located between
the two transducers. The signals received by the second transducer are presented to the receiver input via
the Through connector for amplification and filtering.

PureView™ Pulser-Receiver Operator Manual
Page 13 Imaginant Inc.
PureView Receiver Output, Trig/Sync, and USB Connectors
PureView employs the three connectors shown in the following image for interfacing with other
instrumentation. These three connectors are a Mini-B USB connector for instrument power and control, and
two SMA coaxial connectors labeled Output and Trig / Sync.
PureView receives its power via the USB interface connector and is controlled through this same interface.
The PureView Receiver’s output signal is available on the SMA coaxial connector labeled ‘Output’. The
Receiver circuitry amplifies signals from either the T/R or Through input connectors and presents the amplified
signals on the Output connector. A high-quality 50 Ω coaxial cable should be employed to make a connection
from the PureView Output connector to other instrumentation such as an oscilloscope or waveform digitizer.
This 50 Ωcoaxial cable must be terminated with a 50 Ωload to properly terminate the coaxial cable. The
PureView Receiver can provide a linear output signal of +/- 500mV maximum into a 50 Ω load, and signals of
interest should not be amplified beyond these limits. Over-amplification of signals will lead to signal
distortion.
The Trig / Sync coaxial connector is used to synchronize the PureView unit with external hardware for External
Triggering and Internal Triggering.
External Triggering: When the PureView pulser is set to External Trigger mode, an external trigger signal
must be applied to the Trig / Sync SMA connector to cause the pulser to produce a transducer-excitation
pulse on the T/R connector. The trigger signal must be nominally at 0V (ground) and consist of a positive-
going pulse between 1V and 5V in amplitude. The pulser will then generate a negative-going transducer-
excitation spike-pulse on the T/R connector in response to each positive transition of the trigger signal.
Additional details of this mode of operation are contained in the Operation section.
Internal Triggering: When the PureView pulser is set to Internal Trigger mode, the pulser will generate a
negative-going transducer-excitation spike-pulse on the T/R connector at a rate defined by the Pulse

PureView™ Pulser-Receiver Operator Manual
Page 14 Imaginant Inc.
Repetition Frequency (PRF) value that is set by control software such as JSR .Net Control Panel. To
synchronize the PureView operation to other instruments such as an oscilloscope or waveform digitizer, a
~4V positive-polarity Sync pulse is generated on the Trig/Sync connector in synchronization with the
transducer-excitation pulse. This Synchronization Pulse can then be used to trigger an oscilloscope or
waveform digitizer to capture the waveform present on the PureView Output connector. Additional
details of this mode of operation are contained in the Operation section.
PureView Status Indicators
The PureView front panel has Power and Pulse LED indicators that illuminate to indicate the instrument status
as shown in the image below.
The Power and Pulse LED indicators indicate the following:
Indicator Function
Power
The Blue LED indicates that the PureView Pulser-Receiver is powered On. This LED can be set
to blink (if desired) to identify a particular PureView instrument in a system incorporating
multiple PureView instruments.
Pulse
This Red LED indicates that the unit’s pulser is being triggered. When triggered, the pulser
will produce transducer-excitation pulses on the T/R connector if the pulser voltage supply is
enabled.
PC Setup
JSR .Net Control Panel software is a Windows application written and distributed by Imaginant Inc. You may
install this software on a PC running the Windows®operating system version 7 with SP1, 8.0, 8.1 or 10. Once
you download the software, locate the software installer package and double-click the Setup.exe icon.

PureView™ Pulser-Receiver Operator Manual
Page 15 Imaginant Inc.
Depending on your Windows O/S version, you may need Administrator privileges to run the Setup application.
After you accept the license terms, the software will be installed automatically. The software can then be
launched by clicking the JSR .Net Control Panel icon in the JSR Ultrasonics folder accessed via the Start menu.
With JSR .Net Control Panel installed, you can connect the PureView instrument to the PC directly using the
supplied USB cable. However, it is highly recommended that the PureView instrument be connected to the
PC through a powered hub that can supply at least 1A of current (preferably 2A) to power the PureView unit.
The first time that a PureView instrument is connected to your PC, there may be a slight delay as the operating
system finds and loads the hardware driver necessary for communication with the PureView unit.
To configure a system composed of a PureView instrument and a control PC:
1. Download JSR .Net Control Panel onto the PC.
2. On the PC, locate the software installer package and double-click the Setup.exe icon. The JSR .Net
Control Panel software will be installed. Administrator account permissions may be required for the
installation.
3. Run the JSR .NET Control Panel program to control the PureView instrument.
4. Plug the supplied PureView USB cable into the PureView Mini-B USB connector. Plug the other end of
the USB cable into a USB port on your PC (although it is highly recommended that the PureView
instrument be connected to the PC through a Powered Hub capable of supplying 1A to 2A of current).
The blue power LED indicator on PureView should illuminate. The first time that a PureView unit is
connected to the PC, there may be a slight delay as the operating system finds and loads the hardware
driver required for control and communication.
System Configuration
Refer to the following two figures when configuring a PureView instrument into a test system.
Connect the PureView ‘Output’ connector to the input of an oscilloscope or waveform digitizer. The input
impedance of the oscilloscope or digitizer should be 50 . If the input has a high impedance such as 1M,
then a pass-through coaxial 50 terminator should be added to the input.
Connect the PureView ‘Trig / Sync’ connector as follows:
Internal Triggering: If the PureView pulser is to be triggered by its internal PRF oscillator, connect
PureView’s ’Trig / Sync’ connector to the trigger input of an oscilloscope or waveform digitizer. This
allows the oscilloscope or waveform digitizer to be synchronized to the PureView pulser. The trigger
input of the oscilloscope or digitizer may be terminated in 50 
External Triggering: If the PureView pulser is to be triggered from an external source such as a Sync
signal generated by a waveform digitizer, connect PureView’s ’Trig / Sync’ connector to the trigger output
of the waveform digitizer. The input impedance of the PureView Trig/Sync connector should be set via
control software to 50so as to properly terminate the 50connecting cable.
Connect the PureView connectors labeled T/R and Through as follows (depending on whether Pulse-Echo or
Through operational modes are desired):
Pulse-Echo Configuration
Pulse-Echo operation (also referred to as Transmit/Receive operation) employs a single transducer for both
transmitting and receiving ultrasonic pulses. To configure PureView for T/R operation, the transducer is

PureView Operation
The following sequence of actions describes a typical operating session with a PureView-based measurement
instrument.
1. Configure the PC as described in the ‘PC Setup’ section and the PureView unit as described in the
‘System Configuration’ sections above.
2. Connect a transmit/receive transducer, or separate transmit and receive transducers to the
PureView instrument. Given that high frequency ultrasound will not pass through air, a suitable
acoustic coupling material must be present between the transducer(s) and the sample that is to be
tested.
3. Use the control software to configure the PureView instrument for the desired operation, either
Internal or External Trigger mode, and Pulse-Echo or Through mode.

PureView™ Pulser-Receiver Operator Manual
Page 17 Imaginant Inc.
The PureView red status indicator ‘Pulse’ LED will illuminate to indicate that the pulser is being
triggered. Enable the pulser power supply to produce transducer excitation pulses on the T/R
connector. Adjust the frequency of pulser firing such that all echoes from one excitation pulse
have subsided before a new excitation pulse is generated.
Adjust the Damping and Energy controls to obtain the desired excitation pulse characteristics.
Adjust the receiver gain control so that signals of interest (signals from the PureView Output
connector) do not exceed the range of +500mV to - 500mV into a 50termination.
Adjust the high and low pass filter cutoff frequencies (as desired). The High pass filters can be used
to eliminate low-frequency energy from signals of interest. The low pass filter can be used to
reduce the receiver bandwidth and improve the signal to noise ratio.
IMORTANT NOTE - The PureView receiver contains circuitry to protect its receiver from the large transducer
excitation pulse. The operation of this protection circuit causes two short pulses to appear in the receiver
Output signal, and these pulses bracket the time when the pulser ‘fires’. The first short pulse occurs
approximately 70ns after the rising edge of the Trig / Sync signal. The second short pulse follows the first by
300ns or more (depending on the PureView model).
The Receiver Output signal will not provide any ultrasound signals from its T/R or Through inputs during the
interval of time between these two short pulses. During this interval the Receiver Output waveform contains
no meaningful signal content. Although the two short pulses may look similar to ultrasound signals, neither
of these short pulses is representative of any signals produced by the transducer(s) during that interval.
An example of the receiver-protection pulses is shown below. This is the output of a PureView unit where
the horizontal time scale is 100ns / major division. The purple trace is the PureView Trig / Sync pulse. The
blue trace is the Receiver Output signal with the Receiver gain set to 20dB. The two short pulses in the (blue)
Receiver Output waveform follow the rising edge of the (purple) Trig / Sync pulse by 70ns and 640ns
respectively. The exact timing of these pulses is PureView model dependent and the second pulse may
appear earlier or later in time than what is shown, depending on the model. In some low frequency
PureView models, the second pulse may occur up to 1.2us after the rising edge of the Trig / Sync signal.

PureView™ Pulser-Receiver Operator Manual
Page 18 Imaginant Inc.
The transducer excitation pulse (typically) occurs 160ns after the rising edge of the Trig / Sync signal. As can
be seen in the image above (with a horizontal timescale of 100ns/division), the pulser creates a small
disturbance in the receiver output waveform (blue trace) 160ns after the Trig / Sync signal’s rising edge (purple
trace). This is what appears as a small noise burst 160ns (blue trace) after the rising edge of the (purple) Trig
/ Sync signal.
As described above, the receiver protection circuit does not allow ultrasound signals to pass through the
receiver in the interval between the two short pulses. However, to more precisely determine the point in
time when the receiver begins passing ultrasound signals, a good indication is when the random noise level in
the output signal returns to the same amplitude as before the pulser fired. As an example, the image below
shows the output signal of a PureView unit with the receiver gain set to 70dB. The horizontal time scale is
500ns / major division. The action of the receiver-protection circuit can be seen during the interval when the
noise level in the receiver output signal is reduced. Shortly after the receiver protection ends, the random
noise in the receiver output signal returns to its normal amplitude. At this point in time the receiver is once
again able to pass signals from its input through to its output.
Using JSR .Net Control Panel Software
For installation of the JSR .Net Control software, refer to the ‘PC Setup’ section of this manual.
The JSR .Net Control Panel software enables a user to remotely control a PureView instrument from the user’s
computer running the Windows operating system. In addition to the JSR .Net Control Panel program, an SDK is
available for users that wish to develop custom instrument control software.
Instrument control is provided through commands sent to the PureView instrument via the USB interface. The
available control functions are given below.

PureView™ Pulser-Receiver Operator Manual
Page 19 Imaginant Inc.
Receiver Controls in JSR .Net Control Panel
Power LED
User selectable as a constantly-on power indicator or as a blinking indicator (to identify one PureView
unit from among multiple units in a multi-unit system).
Receiver Mode
This control selects the source for the Receiver’s input signal as either Pulse Echo (selects the T/R
connector) or Through (selects the Through connector).
Gain
This allows a user to select the Receiver gain from -11.5dB to +70dB in steps of 0.5dB.
Low Pass Filter
This control selects either of the Receiver’s two low-pass filter values. Depending on the PureView
model, the low-pass filters may have values of 150MHz, 300MHz, 500MHz, or other values.
High Pass Filter
This control selects either of the Receiver’s two high-pass filter values. Depending on the PureView
model, the high-pass filters may have values of 1MHz, 5MHz, 30MHz, 65MHz, or other values.
Pulser Controls in JSR .Net Control Panel
Trigger Enable
This control allows a user to enable or disable the Pulser from responding to trigger signals.
Trigger Source
This control selects either Internal or External modes of pulser triggering.
For Internal triggering, the pulser is triggered at the rate set by the PRF control that is described
below. A positive-going Sync pulse is produced on the Trig / Sync connector in synchronization
with the pulser firing.
For External triggering, the pulser is triggered by the rising edge of a Trigger Input Signal applied to
the Trig / Sync connector.
If the trigger rate exceeds the maximum pulse repetition frequency (PRF) for the PureView model,
the amplitude of the transducer excitation pulse (on the T/R connector) may be reduced.
PRF
The Pulse Repetition Frequency (PRF) sets the rate of pulser firing rate when a PureView unit is set for
internal trigger mode. The range of PRF values available is dependent on the PureView model.

PureView™ Pulser-Receiver Operator Manual
Page 20 Imaginant Inc.
Pulser Voltage Supply Enable
This checkbox in the software enables or disables the power supply voltage that is supplied to the
Pulser circuitry. Disabling (unchecking) this control will allow all Pulser-Receiver functions to run but
the Pulser will not generate transducer excitation pulses. This control can be useful for debugging
PureView-based test systems.
Pulser Voltage
This displays the pulser power supply voltage. For PureView, this is typically a fixed value that cannot
be adjusted.
Pulser Energy
This control selects the pulser’s energy level. This control will be disabled (greyed out) for PureView
units that have a fixed pulse energy value.
Damping
This control allows the user to select between transducer-damping values. This control will be disabled
(greyed out) for PureView units that have a fixed (single) damping value.
Trigger Zin
This control is used when a PureView unit is set to External Trigger mode and the external trigger
signal is sent to the PureView unit using a 50 Ωcoaxial cable. The ‘Trigger Zin’ control allows a user
to set the input impedance of the Trig / Sync connector to either 50 Ωor High Z (~18kΩ). Selecting a
value of 50 Ωconnects an internal 50 Ωterminating impedance to the Trig / Sync connector which is
appropriate for terminating a 50 Ωcoaxial cable.
You may set the Trigger Zin control to ‘High Z’ to provide a high impedance (~18kΩ) to the Trig / Sync
connector. This would be appropriate for trigger signals originating from a high-impedance source.
Multiple PureView instruments set to External Trigger mode can be triggered from the same external
trigger signal. To do so, their Trig / Sync connectors should be daisy-chained together so that the
trigger signal goes to a first PureView unit, then to a second, then to a third, etc. The ‘Trigger Zin’
value of each of these PureView units (except the last PureView unit) must be set to ‘High Z’. For
proper termination of the coaxial signal, the last PureView in the daisy chain should have its trigger
input impedance set to 50 Ω.
Instrument Status Indicators in JSR .Net Control Panel
Pulsing
The pulsing status LED indicator in the JSR .Net Control Panel software will illuminate red when the pulser is
actively pulsing, and will be grey otherwise.
Power Limit Status
The Power Limit Status light will be green when the PureView pulser voltage is nominal. At high pulser firing
rates (PRF rates) that may cause the pulser voltage to droop, the Power Limit Status light will turn red.
