Welcome to the pulse measurements application
Starting the pulse application
cation
The R&S FSV3 Pulse application is a firmware application that adds functionality to
perform measurements on pulsed signals to the R&S FSV/A.
The R&S FSV3 Pulse application provides measurement and analysis functions for
pulse signals frequently used in radar applications, for example.
The R&S FSV3 Pulse application (R&S FSV/A-K6) features:
●
Automated measurement of many pulse parameters including timing, amplitude,
frequency and phase parameters
●
Statistical analysis of pulse parameters
●
Analysis of "parameter trends" over time and frequency
●
Visualization of the dependency between parameters
●
Display of amplitude, frequency, phase and power spectrum measurement traces
for individual pulses
This user manual contains a description of the functionality that the application provides, including remote control operation.
Functions that are not discussed in this manual are the same as in the Spectrum application and are described in the R&S FSV/A User Manual. The latest version is available for download at the product homepage:
http://www.rohde-schwarz.com/product/FSV3000.html.
Installation
You can find detailed installation instructions in the R&S FSV/A Getting Started manual
or in the Release Notes.
2.1 Starting the pulse application
Pulse measurements require a separate application on the R&S FSV/A.
To activate the R&S FSV3 Pulse application
1. Press the [MODE] key on the front panel of the R&S FSV/A.
A dialog box opens that contains all operating modes and applications currently
available on your R&S FSV/A.
2. Select the "Pulse" item.
13User Manual 1178.9426.02 ─ 07
R&S®FSV3-K6
Welcome to the pulse measurements application
Understanding the display information
The R&S FSV/A opens a new measurement channel for the R&S FSV3 Pulse
application.
The measurement is started immediately with the default settings. It can be configured
in the Pulse "Overview" dialog box, which is displayed when you select the "Overview"
softkey from any menu (see Chapter 5.1, "Configuration overview", on page 62).
Multiple Measurement Channels and Sequencer Function
When you activate an application, a new measurement channel is created which determines the measurement settings for that application. The same application can be activated with different measurement settings by creating several channels for the same
application.
The number of channels that can be configured at the same time depends on the available memory on the instrument.
Only one measurement can be performed at any time, namely the one in the currently
active channel. However, in order to perform the configured measurements consecutively, a Sequencer function is provided.
If activated, the measurements configured in the currently active channels are performed one after the other in the order of the tabs. The currently active measurement is
indicated by a

3 Measurements and result displays
Measurements and result displays
Pulse parameters
During a pulse measurement, I/Q data from the input signal is captured for a specified
time or for a specified record length. Pulses are detected from the signal according to
specified thresholds and user-defined criteria. The measured signal is then compared
with the ideal signal described by the user and any deviations are recorded. The
defined range of measured data is then evaluated to determine characteristic pulse
parameters. These parameters can either be displayed as traces, in a table, or be evaluated statistically over a series of measurements.
Measurement range vs. result range vs. detection range
The measurement range defines which part of an individual pulse is measured (for
example for frequency deviation), whereas the result range determines which data is
displayed on the screen in the form of amplitude, frequency or phase vs. time traces.
The detection range (if enabled) determines which part of the capture buffer is analyzed. The pulse numbers in the result displays are always relative to the current
detection range, that is: pulse number 1 is the first pulse within the detection range in
the capture buffer. If disabled (default), the entire capture buffer is used as the detection range. See also "Detection range" on page 49.
Exporting Table Results to an ASCII File
Measurement result tables can be exported to an ASCII file for further evaluation in
other (external) applications.
For step-by-step instructions on how to export a table, see Chapter 8.3, "How to export
table data", on page 140.

3.1 Pulse parameters
The pulse parameters to be measured are based primarily on the IEEE 181 Standard
181-2003. For detailed descriptions refer to the standard documentation ("IEEE Standard on Transitions, Pulses, and Related Waveforms", from the IEEE Instrumentation
and Measurement (I&M) Society, 7 July 2003).
The following graphic illustrates the main pulse parameters and characteristic values.
(For a definition of the values used to determine the measured pulse parameters see

Timestamp
The time stamp uniquely identifies each pulse in the capture buffer. It is defined as the
time from the capture start point to the beginning of the pulse period of the current
pulse. (As opposed to the pulse number, which is always relative to the start of the
detection range, see also "Detection range" on page 49).
Depending on the user-specified definition of the pulse period, the period begins with
the mid-level crossing of the current pulse's rising edge (period: high-to-low) or the
mid-level crossing of the previous pulse's falling edge (period low-to-high). See also
"Pulse Period" on page 65.
Note: For external triggers, the trigger point within the sample (TPIS) is considered in
the timestamp (see TRACe:IQ:TPISample? on page 294).

3.1.5 Envelope model (cardinal data points) parameters
The pulse envelope model has the shape of a trapezoid of amplitude (V) versus time
(s) values. This model allows for a finite rise and fall time, as well as an amplitude
droop across the top of the pulse. During measurement of each pulse, the points of this
trapezoidal model are determined as the basis for further measurements. For example,
the rise and fall time amplitude thresholds or the "pulse top" duration are determined
from the parameters of the envelope model.

Each of these parameters has a time and an amplitude value. The time values are relative to the pulse timestamp and displayed in seconds. The amplitude values are displayed as power in dBm units.
You configure the desired high, mid and low thresholds for the rise and fall slopes relative to the base (0%) and top (100%) levels. See Chapter 5.9.1, "Measurement levels",
on page 92.
The power value of the rise base point and the fall base point is assumed to be equal
