2 Welcome to the pulse measurements appli-
cation
The R&S VSE-K6 is a firmware application that adds functionality to perform measure-
ments on pulsed signals to the R&S VSE.
The R&S VSE Pulse application provides measurement and analysis functions for
pulse signals frequently used in radar applications, for example.
The R&S VSE Pulse application features:
Measurement of basic pulse characteristics
Analysis of parameter trends over time
Display of amplitude, frequency and phase measurement traces for individual pul-
ses
The additional option R&S VSE-K6A offers multi-channel analysis. It is based on the
premise that a similar pulse is captured on all input channels, with some differences in
the pulse parameters according to timing, amplitude, phase, etc. It is also expected
that the same number of pulses is captured on each input channel. Therefore, the
analysis groups the n-th pulse measured on each input channel into the same
"Selected Pulse" result for the different displays. Thus, you can easily compare the
pulse amplitude and phase values, for example, across all input channels in the same
display.
This user manual contains a description of the functionality that the application pro-
vides, including remote control operation.
Functions that are not discussed in this manual are the same as in the I/Q Analyzer
application and are described in the R&S VSE Base Software User Manual. The latest
version is available for download at the product homepage (http://www.rohde-
schwarz.com/product/VSE.html).
2.1 Starting the pulse application
Pulse measurements require a separate application on the R&S VSE. It is activated by
creating a new measurement channel in Pulse mode.
To activate the Pulse application
1.
Select the "Add Channel" function in the Sequence tool window.
A dialog box opens that contains all operating modes and applications currently
available in your R&S VSE.

tion.

ferent information areas are labeled. They are explained in more detail in the following

In addition, the channel bar also displays information on instrument settings that affect
the measurement results even though this is not immediately apparent from the display
of the measured values (e.g. transducer or trigger settings). This information is dis-
played only when applicable for the current measurement. For details see the
R&S VSE Base Software User Manual.

3 Measurements and result displays
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 eval-
uated 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 ana-
lyzed. 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 detec-
tion range. See also "Detection range" on page 50.
Result display windows
For each measurement, a separate measurement channel is activated. Each measure-
ment channel can provide multiple result displays, which are displayed in individual
windows. The measurement windows can be rearranged and configured in the
R&S VSE to meet your requirements. All windows that belong to the same measure-
ment (including the channel bar) are indicated by a colored line at the top of the win-
dow title bar.
To add further result displays for the Pulse channel, select the "Add Window"
icon from the toolbar, or select the "Window > New Window" menu item.
For details on working with channels and windows see the "Operating Basics"
chapter in the R&S VSE Base Software User Manual.

Evaluation methods for pulse measurements.........................................................29
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 Stan-
dard 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
Chapter 4.1, "Parameter definitions", on page 45.)

In order to obtain these results, select the corresponding parameter in the result config-
uration (see Chapter 6.1, "Result configuration", on page 99) or apply the required
SCPI parameter to the remote command (see Chapter 8.4.11, "Configuring the
results", on page 220 and Chapter 8.6.1, "Retrieving results", on page 302).

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 50).
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 313).

(see"Pulse Period" on page 65) determines whether this value is calculated from con-
secutive rising or falling edges.

Top Power
The median pulse ON power. The value of this parameter is used as a reference
(100%) to determine other parameter values such as the rising / falling thresholds. Var-
ious algorithms are provided to determine the top power (see "Measurement Algo-
rithm" on page 93).

Base Power
The median pulse OFF power. The value of this parameter is used as a reference (0%)
to determine other parameter values such as the rising / falling thresholds.

Pulse Amplitude
The difference between the "Top Power" and the "Base Power", calculated in linear
power units (W). This value determines the 100% power range (amplitude). This value
is converted to dBm for the "Pulse Results" table.

In-Phase Amplitude/Quadrature Amplitude
The pulse in-phase or quadrature amplitude as a voltage, measured at the measure-
ment point of the pulse (see Chapter 5.8.2, "Measurement point", on page 94). Values
range from -10 mV to +10 mV.
