1. General Information
Introduction
This manual provides information about how to install and operate the LB480A/LB680A models for USB Pulse Profiling
PowerSensor+™. Information about product features, specifications, and support is also included. Use the electronic
bookmarks shown below (or the table of contents) to reference product features that include all of the toolbar functions.
Refer to the product Programming Guide for programming information. The Errata and User Update section at the end
of this document reflects recent changes in product development.
It is highly recommended that you begin with the LB480A Quick Start Guide for the Pulse Profiling Application to
quickly learn the basics of instrument operation. Alternately, if you want to use the sensor simply as a CW and pulse
power meter, refer to the LBXXXA Quick Start Guide and Product Manual for the Power Meter Application.
Description
The LB480A USB PowerSensor+™ features a compact power sensor body that connects directly to a desktop or
laptop computer using a standard USB port. A separate power meter is not required. The companion Pulse Profile
Application software provides a front panel display, or Graphical User Interface (GUI),that allows the user to make
typical CW and pulse (modulation) measurements. A programmatic interface is also available for the product.
The LB480A power sensor allows for the complete characterization of RF and microwave signals from 100 MHz to 8
GHz with a dynamic range of -60 to +20 dBm. The LB480A is specifically designed for those applications requiring a
time domain analysis of pulse and other modulated signal formats.
USB Considerations
The Universal Serial Bus (USB) provides adequate power for the sensor under normal circumstances. However, when
using a longer cable (greater than 3-5 meters), or when some laptop or portable computers are used, an active or self-
powered hub may be required. These are available at most computer stores and often sell for under $20.00. The
sensor is powered directly via the USB cable and typically draws 450 mA at 5 VDC(nominal). An active hub will
compensate for the DC voltage drop beyond approximately 3-5 meters. The reason an active hub is recommended
when using a portable computer is to conserve the battery life of the computer. PowerSensor+™ products are USB 2.0
compliant. The following information is provided for reference when selecting a hub:
Bus-powered hub: Draws a maximum of 100 mA at power up and 500 mA during normal operation.
Self-powered hub: Draws a maximum of 100 mA and must supply 500 mA to each port.
Low power, bus-powered functions: Draws a maximum of 100 mA (often applies to portable computers).
High power, bus-powered functions: Self-powered hubs: Draws a maximum of 100 mA and must supply 500 mA to
each port.
Suspended device: Draws a maximum of 0.5 mA

More information related to USB
oSupplied voltage by a host or a powered hub port is between 4.75 V and 5.25 V.
oMaximum voltage drop for bus-powered hubs is 0.35 V from its host or hub to the hub output port.
oNormal operational voltage for functions is 4.75 V (minimum).
How to identify the type of USB port
The PowerSensor+™ requires your computer to have USB 2.0 for correct operation. You can identify what port you
have using the following method or similar depending on your operating system, either Windows 2000 or XP:
Click Start and select Control Panel. Select the Performance and Maintenance category then pick the System icon.
Click the Hardware tab and select Device Manager as shown below. Now expand the Universal Serial Bus
controllers heading and look for the word “Enhanced” or USB2 to indicate that USB 2.0 is present on your computer.

3. Pulse Profiling Overview
Quick Start Guide and Additional Documentation
It is highly recommended that you start with the Quick Start Guide for the Pulse Profiling Application to quickly learn
the basics of instrument operation. This product manual can then be used as a comprehensive reference for additional
information. (Alternately, if you want to use the sensor simply as a CW or pulse power meter, refer to the LBXXXA
Quick Start Guide and Product Manual for the Power Meter Application).
Measurement Capability
The LB480A/LB680A are specifically designed for those applications requiring a time domain analysis of pulse and
other modulated signal formats. Both models use a repetitive under-sampling technique to reconstruct the input
signal. This results in an effective sample rate of up to 48 MS/s. Signals with modulation bandwidths up to 10 MHz can
be measured with a high degree of accuracy
The differences between the two models are frequency range coverage and noise floor. The LB480A is specified from
100 MHz to 8 GHz with a noise floor < -60 dBm for frequencies < 6 GHz. The LB680A is specified from 50 MHz to 20
GHz (18.6 GHz with Type N connectors) and has a noise floor of -40 to -45 dBm.
The application provides five (5) pairs of markers and five (5) pairs of time gates that are used to take measurements.
The time gates allow characterization of the pulse signal to include the following parameters. There is also an
automatic measurement feature that allows all of these measurements to be made with a click of a button:
1. Rise time (RT)
2. Fall time (FT)
3. Pulse width (PW)
4. Pulse repetition time (PRT)
5. Pulse repetition frequency (PRF)
6. Duty cycle (DC)
7. Pulse power (Pls)
8. Peak power (Pk)
9. Average power (Avg)
10. Crest factor (CF or CrF)
11. Overshoot (OvSh)
12. Droop (Droop)
13. On/Off ratio
The gates also provide three groups of canned measurements:
1. Power Set (peak power, pulse power and crest factor)
2. Time & Frequency Set (pulse width, pulse repetition time, pulse repetition frequency)
3. Mixed Set (peak power, crest factor, pulse width, pulse repetition frequency)
Zeroing and Reference Power Calibration
The innovative design (patent pending) of the PowerSensor+™ does not require zeroing or power calibration before
use and there is no provision for zeroing or calibration.

4. The Elements of the Display Panel
Sensor Information
Toolbars
The main elements of the default display are shown below with no signal applied to the sensor. We will demonstrate
the features and functionality of the user interface in the following section of this manual entitled “The Toolbar
Functions”. The main elements of the display are:
The Banner with sensor information
The Toolbars
The Dockable Windows (Panoramic Trace; Measurement Trace; Auto Measure; Results; CDF, CCDF & PDF)
The Banner at the top of the user interface indicates the model number of the power sensor, the unit address, and the
unit serial number. The Toolbars allow you to configure the sensor for any given measurement and provide for
housekeeping tasks. The Dockable Windows or panes give a visual presentation of the input signal to the sensor: The
top graph is called the Panoramic Trace and the bottom graph is called the Measurement Trace. You can highlight a
portion of the Panorama by clicking and dragging the cursor directly on the Panorama View. This highlighted time
segment will then appear in the Measurement View. This allows for a more detailed examination of the signal using
time markers and time gates. The Auto Measure pane allows you to make a comprehensive list of measurements with
a click of a button. The Results pane (inlay) allows you to manually setup the markers and gates for a given
measurement as we will demonstrate. The Results pane shows the measurement readings that include the current
trace values and the marker and gate values. The current trace values are also listed above the grid in the Panorama
View (circled). The Results pane provides convenient access to the tools needed to manipulate the signal display in
the Measurement view. You can scroll left and right; zoom in and out; reset or highlight the span; and select the pointer
mode. The CDF, CCDF & PDF pane gives you some tools for statistical analysis - see Section 6. Statistics.
The Dockable Windows can be repositioned to maximize the display areas. We will explain the docking features next
to allow you to manage the display presentation to your liking.

Dockable Windows
You can position any of the five dockable windows (or panes) anywhere on the panel using the docking feature. You
can also auto-hide a pane(s). We will demonstrate both in the following sequence. To activate the docking popup click
and drag the cursor from one of the dockable window tabs. Then select a position (top, bottom, center, right, left) on
the popup to place that display or pane on the panel.
We will demonstrate moving the Results pane over the Panoramic Trace in the next three screen shots: First, drag
the Results tab over the Panoramic Trace and hold until the docking popup appears as shown below. See how the
drop zone becomes highlighted. Now release the mouse on the center overlay position on the Panoramic Trace. Do
the same thing with the Auto Measure pane.

Next, drag the Measurement Trace tab over the Panoramic Trace and drop it in the center of the docking popup like
we just demonstrated. You will see the screen below with the Measurement Trace expanded even more with no
stimulus applied to the sensor.
NOTE: You can also drag a docking tab onto the desktop (not shown). Double click on it or drag it back on the panel,
then position it as previously described. You can adjust the size of each pane by clicking and dragging along the
border areas as is typically done.

Lastly, we demonstrate the Auto-Hide feature of dockable windows from the previous screen. Drag the Measurement
Trace tab down until the docking popup appears and drop it on the bottom Auto-Hide positioner as shown below.
The Measurement Trace will move to the position indicated with Auto-Hide active as shown below. This means the
display is not pinned to the panel and you must point to the Measurement Trace tab to view it. Toggle the Auto-Hide
icon to turn this feature off or to pin the pane to the panel for continuous viewing.
NOTE: A docking tab must be pinned or, in other words, Auto-Hide must be off in order to move it to another location.
The next section of this manual covers the toolbar functions.The toolbars comprise the largest section of this manual.

5. The Toolbar Functions
Display Control Toolbar (Pointer Control)
Results Pane
Zoom
Reset
Highlight (Mode)
Markers (Mode)
Gates (Mode)
The Pulse Profile Application is designed to be highly interactive using the mouse. The mouse pointer has three
modes of operation: Highlight, Markers and Gates . The Pointer Control (highlighted in yellow below) shows what
mode is active for cursor control. The default mode is Highlight. These controls are available from the Display
Control toolbar and in the Results pane for easy access. The screen below shows an arbitrary input to the sensor.
The mouse pointer is in Highlight mode and a section of the span on the Panoramic Trace has been highlighted.
This highlighted time seqment appears as the bottom Measurement Trace to allow for closer examination. Again, the
Display Control toolbar mimics the same controls in the Results pane so you can readily tell what mode is active.
Highlight is used in conjunction with Markers and Gates to take measurements. These measurements will then be
displayed in the Results pane. The Trace Measurements in the Results pane will always indicate the Peak, Pulse,
CrF (Crest Factor), Average (power in the pulse), and Duty Cycle. You can expand or collapse the individual headers
in the Results pane. Notice that there is a short discription of each toolbar function when you hover over it with the
cursor.

The screen shots in this document use the following input to the LB480A sensor for demonstration purposes:
Carrier Frequency = 1 GHz
Modulation = ~50 kHz Pulse
Duty Cycle = ~10%
Pulse Width = ~2 usec
Power = ~-20 dBm
Sweep Time = 1 msec
Highlight Span
The Panoramic Trace and the Measurement Trace are designed to work in tandem to help the user identify and
investigate areas of interest easily and quickly. To view a portion of the Panoramic Trace in more detail you need only
select or highlight the portion of the trace in which you are interested. Refer to the screen shot below for the following
discussion. After selecting Highlight mode, you can select a span in either the Panorama or Measurement views by
dragging the cursor over the display. You can scroll, nudge or zoom in and out across the span or Reset it. You can
also highlight a specified percentage of the span from the Highlight Span drop down. Highlight Span allows you to
highlight a specified percentage of the sweep instead of pointing and clicking the cursor over the span. You can
precisely set the point in time to start the highlighted percentage of the trace using the Set Start menu selection.

You can highlight or select a portion of the trace using the following techniques:
1. Click and drag the mouse over a portion of the Panoramic Trace –only the portion selected by the mouse
movement will be viewed in the Measurement Trace.
2. Click and drag the mouse over a portion of the Measurement Trace –only the portion selected by the mouse
movement will be viewed in the Measurement Trace. This technique allows you to sequentially zoom in on a
small portion of the trace. The mouse pointer must be in Highlight mode.
3. Click the Highlight Span drop down on the Results pane (or Display Control toolbar) and then select the
percentage of interest. The selected portion will be viewable in the Measurement Trace understanding that:
a. If a portion of the trace is currently being viewed the highlight of the selected percentage will be centered on
the current area of interest.
b. If a portion of the trace is not selected then the percentage will be centered around the middle of the current
panorama trace.
4. To select a precise portion of the trace click the Highlight Span drop down and then select Set Start. Enter the
beginning of the measurement trace in microseconds. Doing this in conjunction with the previous option allows you
to select a very precise portion of the trace.
5. Click the Zoom In or Zoom Out buttons. These buttons double or halve the current viewing area. These buttons
are available in the Results pane and in the Display Control toolbar.
6. Click the Reset button –this causes the entire Panoramic Trace to be made viewable in the Measurement Trace
window. In other words, resetting selects the entire Panoramic Trace.
7. Use the scroll and nudge controls in the Results pane. These controls allow you to scroll the area of interest left or
right. The nudge controls move the area one small step at a time.
Once you configure the input to your sensor it is helpful to practice using the highlight and the scroll/zoom/nudge
controls to see the effect.
