EX10xxA Introduction 15
SECTION 1
INTRODUCTION
OVERVIEW
The EX10xxA family of products provides a total of 48-channels, with an exception of RX10xx
products which has 32-channels, of high-performance thermocouple and/or voltage measurement in
a single instrument. This family includes the EX1000A, EX1000A-TC, EX1016A, EX1032A,
EX1048A, EX1000A-51C and RX1032. The last two digits of the model name indicate the number
of thermocouple channels/voltage channels available on the model. For example, the EX1016A has
sixteen thermocouple channels and thirty-two voltage channels. Its combination of measurement
performance and integrity, configuration flexibility, package density, and network connectivity
make it the most powerful, yet easy-to-use, instrument of its kind. The EX10xxA is a complete, self-
contained temperature measurement system that communicates over Ethernet. Unlike other data
acquisition offerings in its class, the EX10xxA offers a tightly integrated solution that frees the user
from the complexity of marrying terminal blocks, signal conditioning cards, digitizer, power supply,
and chassis together.
EX1000A-51C is the enhanced version of the EX10xxA family of products, has 51 Voltage
Channels and has additional features such as additional sensors to measure internal box temperature
and additional API’s provided to read UTC offset & warmup time.
RX10xx is the rugged version of the EX10xxA family of products, has 32 Channels and most
importantly provides the user with the flexibility to place this instrument even in extreme conditions
and directly in the test cells because of its rugged build.
EX1044 is the customized version of the EX10xxA family of products, has 44 TC Channels and 2
channels for voltage/current respectively. This provides thermal labs customers the ability to place
instrumentation directly in the thermal test labs. The EX10xx product has already demonstrated
some of the highest accuracy in the market for Thermocouple measurements and the EX1044 will
continue to provide as good or better accuracy for gas turbine test cell users trying to improve engine
efficiency by better understanding temperature effects on the DUT.
The EX10xxA also provides a level of measurement integrity and channel independence that far
exceeds the typical data acquisition system. Absent are caveats about scanning speed, channel order,
and overload effects. In the EX10xxA, channels have no influence on each other, regardless of
scanning speed or channel state. Excellent common mode rejection performance provides immunity
from not only power line interference, but also high frequency noise. Moreover, it aids in
maintaining overall system integrity by offering a high-performance open transducer detection
system.
The EX10xxA provides a high level of configuration flexibility as well. Each channel can be
configured independently with regards to measurement function, hardware filter setting, and limit
values. In addition to measuring all standard thermocouples, the EX10xxA can be programmed with

VTI Instruments Corp.
16 EX10xxA Introduction
user-defined thermocouple polynomial equations or be used as a low-noise voltmeter. Scanning
speed is programmable up to a maximum of 1 kSa/s, independent of the number of channels being
scanned. This combination of filtering and scanning speed provides the EX10xxA with the low noise
performance required for sensitive applications as well as the speed necessary to measure fast, fine-
gauge thermocouples.
For highest accuracy and stability, the EX10xxA provides an embedded isothermal input section
that is monitored by up to twelve precision thermistors (depending on model), one for every four
thermocouple channels. Moreover, it features an internal calibration source that can be used to self-
calibrate the unit upon command. This extends the unit’s high accuracy over a wide ambient
temperature range. Thermocouple accuracy is detailed in Table 1-2.
The EX10xxA is as easy-to-use as it is powerful. An integrated web page provides a convenient
way to instantly verify communications and instrument functionality, while industry standard VXI
plug & play and IVI drivers provide a familiar application programming interface to reduce
integration and program development time.
FEATURES
Combined Thermocouple and Analog Inputs
Easily combine thermocouple and analog signals on these versatile instruments with sampling rates
up to 1 kSa/s (kilo samples per second) per channel. Each input incorporates an independent signal
conditioning path with software selectable filters for maximum flexibility. Complete channel
independence ensures data integrity regardless of sample speed or input overload conditions.
End-to-end Self-calibration
Complete end-to-end self-calibration is provided for each signal path on a programmable basis. A
highly accurate calibration source provides reference signals that are applied prior to analogfiltering
and gain circuits to compensate for drift, aging, or temperature variations. Self-calibration is simple
and quick, and can be performed as often as desired.
Scalable for Synchronized High-Speed, High-Channel Count
With LXI™Class A compliant features like a built-in Trigger Bus™ hardware trigger subsystem,
the EX10xxA supports easy integration and synchronization of multiple devices, including existing
VXI bus instrumentation.
Open Thermocouple Detection (OTD)
While the integration of the EX10xxA removes many of the reliability and connectivity problems
typically faced by system designers, they still must contend with the reliability of the sensor
connections. Fortunately, the EX10xxA aids a great deal in that regard as well. Each thermocouple
input channel generates a very small current (±7.5 nA/channel) which drives the input to an open-
circuit state if the transducer is disconnected. Implemented in this way, open transducer detection is
continuous and requires no discrete function call on the part of the user to be activated, offering
more protection than systems that only check on command, as a broken sensor can occur at any time
during testing, not just at installation. In a typical application, the OTD has no effect on the
measurement. However, many thermocouple simulators have a much higher impedance than a
thermocouple so an offset may be introduced into the reading when using a simulator. In general,
the OTD should only be active on channels that are being used with actual thermocouples.
The EX10xxA additionally offers a front panel OTD LED for each channel that illuminates upon
the recognition of a fault condition. This provides for quick and easy problem channel identification.
Moreover, to ensure that even intermittent problems are identified, the fault recognition is a latching
mechanism, retaining the information of the current acquisition sequence until a new acquisition is
initiated. Note that voltage channels do not include internal CJC thermistors, but that each voltage
D-sub includes connections for the connection of user-supplied thermistors.

www.vtiinstruments.com
EX10xxA Introduction 17
Note: OTD functionality will not be applicable for EX1000A-51C. RX1032 doesn’t have option to
provide OTD LED indication in a fault condition due to its rugged design.
Cold Junction Compensation (CJC)
For highest accuracy and stability, the EX1000A-TC, EX1016A, EX1032A, EX1048A RX1032
provide embedded isothermal input sections that are monitored by precision thermistors (based on
Model#, the number of thermistors can vary), one for every four thermocouple channels. (Note, the
EX1000A may utilize external thermistors as described in the Voltage Connections section). To
ensure that the CJC information is current and time correlated with the input channels, the CJC
channels are measured with every scan, providing a maximum time separation of less than 4 ms
between the measurement of an input channel and its associated CJC measurement. For those users
that prefer to employ an external cold junction, the EX10xxA also allows for the programming input
of up to forty-eight unique external cold junction temperatures, one for every input channel.
Moreover, the use of internal and external CJC inputs can be mixed throughout the unit on a per
channel basis.
Simplified Installation, Setup and Control
Full LXI Class A compliance makes the EX10xxA of instruments ideal for distributed
measurements throughout a facility –reducing cabling and installation expense. Connect directly to
an Ethernet network using industry standard Ethernet cable and connections. Experience how
plug&play capability simplifies installation and setup.
An onboard, web-accessible user interface allows you to instantly verify communications and
instrument functionality, while IVI and VXI plug&play drivers provide a familiar application
programming interface to further reduce integration and program development time. For
comprehensive, programming-free data recording setup, management and viewing, use EX10xxA
instruments with one of VTI’s full-featured, turnkey software solutions: EXLab or VTICODA.
Channel Independence
Each of the EX10xxA’s 48 differential input channels is an independent signal conditioning path,
complete with amplification, programmable hardware filtering, and continuous open transducer
detection. This independence frees the user from the problem of channel-to-channel crosstalk that
is pervasive in most multi-channel data acquisition systems. In the EX10xxA, channels have no
influence on each other, regardless of scanning speed or channel state. Specifically, open or
significantly overloaded channels do not affect the measurement results of any other channels.
Measurement Range
The measurement range of the EX10xxA in terms of temperature is a function of its input voltage
range and the capabilities of the thermocouple sensors themselves. Specifically, the measurement
range of the EX10xxA for the standard thermocouple types is the following:
Type
Min Temp

TABLE 1-1: EX10XXAMEASUREMENT RANGE

VTI Instruments Corp.
18 EX10xxA Introduction
In terms of voltage, the thermocouple connectors may only accept an input voltage of ±67 mV when
performing temperature conversion. When in voltage mode, these connectors can accept either
±0.067 V or ±0.1 V inputs. The voltage connectors may use either ±0.01 V, ±0.067 V, ±0.1 V,
±1.0 V, or ±10.0 V inputs for both EU temperature conversion or voltage measurements. When
temperature is selected, the instrument automatically switches the selected channel(s) to the ±67 mV
range. The EX1000A-TC is a special case where thermocouple inputs are used for voltage
measurement and may utilize all input ranges available to the voltage connectors. Table 1- provides
an overview of each models capabilities.
For maximum flexibility, each channel can be independently configured with regards to its
thermocouple conversion. Moreover, non-standard thermocouples are accommodated through the
input of user-defined thermocouple polynomial coefficients.
Hardware Filter
Each EX10xxA input channel can be individually configured with one of six low-pass hardware
filters. Five of these filters are 2-pole Bessel filters with frequencies of 4 Hz, 15 Hz, 40 Hz, 100 Hz
and 500 Hz. The sixth filter is a single-pole Butterworth filter with a frequency of 1 kHz, providing
a simple anti-alias filter when the 1 kSa/s range is used. These filters allow the EX10xxA to cover
a diverse range of applications, even within the same unit. Suitable for most applications, the 4 Hz
setting provides the lowest noise floor and exceptional common mode rejection. For higher speed
applications, the 1 kHz filter will pass the output from even the fastest fine-gauge thermocouples
with little distortion.
Input Connectors
The EX1016A, EX1032A, and EX1048A employ uncompensated (Cu-Cu) mini-thermocouple
female jacks as an input connector. This connector provides a solid, reliable connection that is also
easily changeable. Since it is not thermocouple-type specific, different thermocouple types can be
mixed throughout the unit without hardware modification. The EX1000A, EX1016A and EX1032A
also employ a standard 50-pin D-sub connector for the voltage input channels. All the RX10xx
channels are individually routed via the screw terminals which is placed just below the instrument
top cover and the cable bunch is brought out through the cable gland.
Sampling Rate
The EX10xxA can be configured for a sampling rate up to a maximum of 1 kSa/s, regardless of the
number of channels included in the scan list. When the requested sampling rate is significantly less
than 1 kSa/s, however, the EX10xxA automatically takes and averages multiple samples. This offers
improved noise performance, while maintaining the requested data output rate.
Digital I/O and Limits
The EX10xxA provides two unique sets of programmable limits that are used for open transducer
detection as well as general purpose input channel monitoring. These limits are programmable on a
per channel basis and are evaluated with each completed scan. The output of limit evaluations is
presented in three forms. The operation of the front panel LEDs is tied to the upper and lower limit
values of one limit set. The operation of the digital I/O port can be optionally linked to any
combination of the upper and lower limit values of either or both limit sets. Finally, the limit
condition information is accessible through the instrument driver.
The EX10xxA features an 8-channel digital I/O port on the rear panel of the instrument, except
RX10xx which has 2-channel digital I/O routed through the 13 pin circular connector (P1). This
port can be used as an arm/trigger source, for presentation of limit evaluation information, and as a
general purpose output device. As a general purpose output device, each DIO channel can be
independently programmed with regards to its output functionality and its static level to assume
when enabled as an output. For expanded and more automated operation, each DIO channel can be
independently linked to one or multiple limit conditions on one or more input channels.

www.vtiinstruments.com
EX10xxA Introduction 19
LXI Trigger Bus
The EX10xxA features an 8-channel LXI (LAN eXtensions for Instrumentation) trigger bus on the
rear panel of the instrument. This differential-pair LVDS (Low Voltage Differential Signal) bus
consists of two identical ports connected in parallel. The primary use of the trigger bus is the
transmission of high-speed signals for multiple-unit triggering and synchronization.
Note: RX1032 doesn’t have LXI trigger bus.
Triggering
The EX10xxA supports a full function trigger model with a separate arm source and trigger source
event structure. Trigger and arm source events can be independently programmed from a variety of
sources including Immediate, Timer, Digital I/O, LAN events, the LXI Trigger Bus, and the LXI
alarm.
