2.3 Licensing
A license is not required for the demo version of the R&S Pulse Sequencer Digital.
Running the R&S Pulse Sequencer Digital in standard mode requires a valid core
license R&S PULSE-K32, and, depending on the desired features, additional licenses
for options, like R&S PULSE-K39 for expert mode are required.
R&S PULSE-LD
The R&S Pulse Sequencer Digital software requires a smart card containing the software license to be connected to the PC when you are using the software. The
R&S PULSE-LD license provider contains the purchased software license and consists
of a smart card and a USB dongle. The R&S PULSE-LD is available as a separate
product and must be ordered in addition to the software.
To obtain the license provider R&S PULSE-LD and license activation codes for
R&S PULSE-K32 or R&S PULSE-K39, contact Rohde & Schwarz support.

2.6 Software concept in brief
The following is brief introduction to the software concept and the way it handles files
and settings.
Repository
The R&S Pulse Sequencer Digital organizes the data in repositories.
A repository is a file-based database located on the local hard drive or on a network
storage drive.
Repositories are entirely managed by the R&S Pulse Sequencer Digital. They can be
password protected against unauthorized access. Repositories can be exported as
archives and shared among multiple users if they are located on a network drive. Several users can have read permission to load and use the same repository simultaneously. However, only one user can have a write permission at a time.
When you create a repository in one operational mode, it is not always compatible with
the other modes. For a description see "Create" on page 64.
Getting started
Software concept in brief
For more information, see Chapter 4, "Organizing the project data in repositories",
on page 60.
Scenario
The scenario is the top-level description of the signals to be generated.
The type of the scenario determines which kind of signal is calculated and how this signal is processed. A more complex scenario combines several signals. Scenarios can
also contain information about the time variation of the signals.
Starting a scenario creates the simulated data and exports them to user-written plugins.
For more information, see Chapter 5, "Selecting a suitable scenario and creating sce-
narios", on page 70.
Platform
A platform is a group of up to 8 emitters assigned to a single vehicle. A platform can
be static or moving. A platform is characterized by its icon, list of emitters, position and
trajectory. The emitters on a platform can be individually configured.
For more information, see Chapter 12, "Creating platforms", on page 239.
Emitter
Emitters emulate radar systems. The emitter combines a sequence, an antenna scan,
and an antenna pattern to one logical unit.
An emitter can work in more than one operating mode and switch between them. The
operating mode is a description of the radar purpose, such as scanning, searching or
tracking. For example, an airport surveillance radar can switch between different scan
types to observe its airspace.
29User Manual 1179.3873.02 ─ 03
R&S®PULSE-K32/-K39
Each mode can have individual antenna and signal configuration. Multiple beams are
possible within a mode.
For more information, see Chapter 16, "Creating complex 2D scenarios with receiver
and TX items", on page 281.
Antenna
The antenna characterizes the radiation pattern of the emitter. Typical radar antennas like the phase array antennas can adapt their radiation pattern dynamically,
depending on the operating mode the radar is working in. For example, an antenna
can use a cosecant beam in scan mode and pencil beam in track mode.
Antennas can have various scan types. The scan type describes the movement of the
antenna. For example, circular, sector and custom.
For more information, see Chapter 9, "Defining antenna patterns and antenna scans",
on page 164.
Receiver
Getting started
Software concept in brief
Receivers are used to model direction finding systems. They comprise of up to 20
individual antennas with individual patterns and positioning relative to a direction finding system.
Option: R&S PULSE-K39 required for direction finding.
For more information, see Chapter 13, "Emulating receivers", on page 252.
Sequence
A sequence describes how pulses are arranged to form a waveform. The most simple
sequence comprises one pulse that is repeated with a constant PRI (pulse repetition
interval). Typical sequences however are rather complex; they can contain pulse definitions, waveforms, and sequencing elements such as repetitions and loops.
The sequence is a logical description. It cannot directly be represented as an I/Q
waveform.
For more information, see Chapter 7, "Building pulse sequences", on page 115.
Pulse
In the R&S Pulse Sequencer Digital, pulses are the fundamental building block of
any signal. Pulses are described mathematically with their amplitude (envelope), the
applied modulation on pulse (MOP) and the enabled marker signals. One single pulse
description is however not sufficient to calculate (and process) a signal; pulses have to
be organized in a sequence, and assigned to an emitter.
For more information, see Chapter 6, "Creating a pulse library", on page 89.
Imported signals
30User Manual 1179.3873.02 ─ 03
R&S®PULSE-K32/-K39
In addition to creating pulse signals you can also load PDW files and use them in
sequences.
For more information, see Chapter 18, "Working with PDWs", on page 347.
Plugins
A plugin is an extension to the standard functions of the R&S Pulse Sequencer Digital.
For even more flexibility, plugins can contain variables.
To export the simulated signal from the R&S Pulse Sequencer Digital, you can write
"export" plugins that are customized to your interfaces. The export plugin enables you
to extract the digital simulation data from the application in a defined format and export
it to different formats or directly stream the data.
For more information, see "How to import and assign user defined plugins"
on page 369.
Getting started
Means of users interaction
2.7 Means of users interaction
This chapter provides an overview on how to work with the R&S Pulse Sequencer Digital and describes the manual operation of the software and also the alternative ways of
operation.
There are two ways to operate the R&S Pulse Sequencer Digital:
●
Manual operation:
Run the software on your PC and use the mouse and/or keyboard.
●
Remote control:
Create programs to automate settings, tests and measurements. The software is
controlled by a program, running on the same or on another computer.
This way of operation is described Chapter 23, "Automation of R&S Pulse
Sequencer Digital", on page 399.
Basic operation concept
This section lists settings and functions that are common to the dialogs and are performed in the same manner throughout the software. You can use them alternatively or
complementary.
As described in Chapter 2.6, "Software concept in brief", on page 29, the R&S Pulse
Sequencer Digital software is based on a relational database that organizes database
elements within repositories. Database elements are indicated by their names; within
one repository, element names must be unique (see "Name and comment"
on page 26).
31User Manual 1179.3873.02 ─ 03
R&S®PULSE-K32/-K39
Creating elements
Once created, database elements can be used by other elements within the same
repository. Elements can be created in both the bottom-up and the top-down direction,
or in a combination of these two methods:
●
Bottom-up: you can create your pulse and waveform library first, then build
sequences, create scenarios, and use the created sequences or assign them to
emitters.
●
Top-down: create your scenario, create emitter, define the antenna pattern/scan,
define the used sequence, and define the pulses and waveforms.
Getting started
Means of users interaction

6 = Pulse and waveform level
7a, 7b = Creating elements at any level with clone and copy
For information on the naming conventions and description of the database elements,
see Chapter 2.6, "Software concept in brief", on page 29.
Handling database elements
While creating database elements, consider also the following possibilities:
●
Change
Files describing elements are stored once but can be used several times. When
one file is changed, its parent elements are also updated.
●
Clone
Elements can be cloned to create a deep copy of the database element.
●
Delete
Elements can be deleted if they are not referenced by other elements.
●
Copy
If two repositories are opened in the project tree, a drag and drop operation creates
a copy of the selected element and all referenced elements.

Overview
The R&S Pulse Sequencer Digital runs as a standalone, PC-based application that
creates simulated PDW datastreams that you can export to a customized plugin.
The software hands the simulated data to a so-called "destination", which wraps a
user-written plugin that receives the data.
You can add as many destinations as you need. To enable you to export a PDW datastream, you need to assign an export plugin to a destination.
R&S Pulse Sequencer Digital plugins are user-configurable, enabling you to define the
export content and format.
See:
●
Chapter 3.1, "Creating and using export plugins", on page 50
●
Chapter 3.2, "PDW export plugin interface specification", on page 52
●
Chapter 3.3, "Destinations settings", on page 56
●
Chapter C, "Plug-in programming API", on page 624.
Preparing for use
Creating and using export plugins
3.1 Creating and using export plugins
To use export plugins in R&S Pulse Sequencer Digital, you need to load a plugin of this
type and map it to a destination.
The following chapters explain how to perform these steps.
For a detailed description of the programming API for the plugin, see Chapter C.2,
"Export plugin", on page 629.
Creating an export plugin
R&S Pulse Sequencer Digital is delivered with the necessary resources to enable you
to create plugins to export the simulated signals.
We recommend using an application such as Visual Studio to open the resource files
and create the plugin. However, you can use an alternative compiler if you prefer. The
plugin exports an extern "C" interface which ensures the compatibility of the DLL.
Access:
1. Perform one of the following:
● In the menu bar, select "Help > SDK > Export_PDW > src"
● On the main toolbar, select the icon "Open SDK folder > Export_PDW > src".
This folder contains example resource files that you can modify as required.
2. Open the solution file, PulseSequencer_Plugin.sln.
3. Change the build configuration to "Release".
50User Manual 1179.3873.02 ─ 03
R&S®PULSE-K32/-K39
4. Rebuild the solution.
The export plugin is in the "Export_PDW > bin" folder and ready for loading into
R&S Pulse Sequencer Digital.
Debugging the export plugin
To debug the DLL
1. Load the plugin project in Visual Studio or your preferred compiler.
2. Set the configuration to "Debug".
3. Set the target path to the location of the R&S Pulse Sequencer Digital executable
file.
4. Start the debugger.
PS-DIGITAL.exe starts.
5. Ensure that the PDB debug file is in the same folder as the DLL so that the debug-
ging symbols load correctly and you can set the breakpoints.
Normally the file location selected automatically by the debug build is correct.
Preparing for use
Creating and using export plugins
6. When the DLL is loaded into R&S Pulse Sequencer Digital, you can start debug-
ging the plugin code in Visual Studio.
Loading an export plugin
To load an export plugin in to R&S Pulse Sequencer Digital, follow the same steps as
for other plugin types.
For details, see "To import a plugin" on page 369.
Navigate to the "SDK > Export_PDW > bin" folder to select the export plugin.
Mapping plugins to destinations
When an export plugin is loaded as described in Loading an export plugin, you can
map it to a destination in R&S Pulse Sequencer Digital.
Access:
1. Perform one of the following:
● In the menu bar, select "Configure" > "Destinations"
● In the block diagram of a scenario, select "Signal Generation" > "Config" >
"Destinations".
The "Destinations" dialog opens.
51User Manual 1179.3873.02 ─ 03
R&S®PULSE-K32/-K39
2. To add a new destination, in "Available Destinations" select "Add a new destination".
A new entry displays at the end of the list, assigned with the next free number.
3. To edit the destination name, double-click in the "Destination" field.
4. Select an available plugin fom the "Plugin" drop-down list.
Preparing for use
PDW export plugin interface specification
5. To edit the name or comment parameters, or to change the selected DLL, select
"Edit".
The "Plugin" dialog opens.
6. Edit the plugin variables on the right as required.
The plugin is mapped to the specified destination and ready for use in a scenario.
For a description of how to assign signals to destinations, see Chapter 17.2, "Assign
signals to destination", on page 343.
3.2 PDW export plugin interface specification
The export plugin that R&S Pulse Sequencer Digital uses for the simulated signals is
user-configurable. You can adapt the plugin for streaming or transferring the data as
you require, including the content of the data.
The format of the PDW data at the export plugin interface function is a
Rohde & Schwarz proprietary format as described in this chapter. In the plugin, the
user is free to extract any needed information and adapt the data formats or representation of the values to map it to any needed format.
Depending on the scenario you are using and your export needs, some of the following
parameters might not be necessary.
Parameters that are not set represent an invalid value. Parameters that do not have an
invalid representation are guaranteed to be valid.
The serialized data uses little endian byte order.
52User Manual 1179.3873.02 ─ 03
R&S®PULSE-K32/-K39
Preparing for use
PDW export plugin interface specification
Data type
The invalid value depends on the data type:
●
uint8/16/32
The invalid case is defined as all 1's in bit representation, which means 0xFF,
0xFFFF, ... in hex.
For unsigned integers, it is the definition of the maximum value that is possible,
therefore the valid data range is limited by 1.
For example, for uint8 the data range is [0, 254] in decimal representation, as 255
is used to indicate the invalid case.
●
int16
The invalid case is defined as 0x8000, which represents the minimum value
-32768. Therefore the valid data range for int16 is [-32767, 32767].
●
float32
The invalid case is defined as 0x7F7FFFFF, which represents the maximum available float number regarding IEEE-754.

5 Selecting a suitable scenario and creating
scenarios
This section explains the provided scenario types and helps you select the scenario
most fitting to your current task.
5.1 Overview of the available scenarios and their complexity
The R&S Pulse Sequencer Digital supports six scenarios with different complexity.
Select the scenario most fitting your test case:
●
Single sequence
The single sequence scenario is used to create sequences from individual pulses.
Pulse parameters include the pulse envelope, modulation on pulse (MOP), carrier
frequency, and level. The sequence editor defines the order in which the pulses are
generated and also adds control elements such as loops and fillers. Inter-pulse
modulation profiles can be applied to vary pulse parameters.
●
Sequences (collection)
The sequences (collection) scenario is used to create multiple sequences which
can be selected in arbitrary order.
Pulse parameters include the pulse envelope, modulation on pulse (MOP), carrier
frequency, and level. The sequence editor defines the order in which the pulses are
generated and also adds control elements such as loops and fillers. Inter-pulse
modulation profiles can be applied to vary pulse parameters.
●
Single emitter
The emitter scenario combines a pulse train with an antenna pattern and a particular antenna scan type. An emitter comprises several modes. Each mode is defined
by an antenna pattern and an antenna scan, and multiple beams that contain the
pulse train.
●
Emitters (collection)
The emitter collection scenario provides a choice of multiple emitters that can be
selected manually. An emitter comprises several modes. Each mode is defined by
an antenna pattern and an antenna scan, and multiple beams that contain the
pulse train.
Multiple emitters can be interleaved into multiple output files using groups and a
priority-based dropping algorithm.
If pulses are overlapping, the pulses with the lower priority are dropped.
●
Localized emitters
The localized emitters scenario combines multiple emitters and one receiver on a
2D map. An emitter comprises several modes. Each mode is defined by an
antenna pattern and an antenna scan, and multiple beams that contain the pulse
train. The receiver is defined by a single antenna pattern and scan.
Multiple emitters can be interleaved into multiple output files using groups and a
priority-based dropping algorithm.
Selecting a suitable scenario and creating scenarios
Overview of the available scenarios and their complexity
70User Manual 1179.3873.02 ─ 03
R&S®PULSE-K32/-K39
If pulses are overlapping, the pulses with the lower priority are dropped.
●
Direction finding
Option: R&S PULSE-K39
The direction finding scenario simulates multiple emitters and a single receiver with
up to 10 antennas on a 2D map.
The individual signals for each receive antenna are simulated to enable the
receiver to locate the position of a signal source.
Multiple emitters can be interleaved into multiple output files using groups and a
priority-based dropping algorithm.
If pulses are overlapping, the pulses with the lower priority are dropped.
●
PDW list (collection)
The PDW list collection finding scenario provides a choice of multiple PDW lists
that can be selected manually. This scenario generates a Rohde & Schwarz proprietary PDW-based signal from a list of imported PDWs in custom format.
Imported PDW lists are read from a waveform object.
Multiple emitters can be interleaved into multiple output files using groups and a
priority-based dropping algorithm.
Option: R&S PULSE-K39 required for interleaving.
If PDWs are overlapping, the PDWs with the lower priority are dropped.
See Chapter 18, "Working with PDWs", on page 347.

6.2.3.4 Chirp modulation
A chirp is a signal in which the frequency varies over the time. The chirp sweeps the
RF signal across a set frequency range.
The chirp modulation scheme is used for pulse compression.
Settings:
Linear Chirp...................................................................................................................99
Piecewise Linear Chirp............................................................................................... 100
Custom Chirp.............................................................................................................. 101
Polynomial Chirp.........................................................................................................103
Linear Chirp
The linear chirp varies the frequency linearly over time.
Symbol rate of the modulating signal.
Inverts the MSK modulation.

"Deviation"
Defines the frequency variation:
●
Linearly increasing ("UPp")
●
Linearly decreasing ("Down")
●
Following a full sine wave ("Sine")
●
Ascending and then descending ("Triangular")

Piecewise Linear Chirp
Define the chirp as a sequence of chirp intervals with user-definable length and frequency deviation.
Figure 6-4: Piecewise Linear Chirp: understanding the displayed information
1 = Offset = 0 Hz; the start chirp frequency is 0 Hz
2, 3, 4 =
5 = In the remaining 34% of the chirp time, the frequency is kept constant
6 = Positive offset; the start chirp frequency in the second interval is 10 MHz
7 = Negative offset; the start chirp frequency in the third interval is -10 MHz
* = Theoretical example, in practice you rather vary the frequency during the whole time
Three chirp intervals with total duration of 66% of the whole time of which the MOP is applied
