R&S®Pulse Sequencer (DFS)
1 Welcome to the R&S Pulse Sequencer
(DFS)
Worldwide, the two frequency bands 5.25 GHz to 5.35 GHz and
5.47 GHz to 5.725 GHz are used by various radar systems. In addition, they are allocated to unlicensed WLAN devices. A requirement arising from this frequency band reuse
is a method called Dynamic Frequency Selection (DFS).
A system that requires DFS must be capable to avoid interfering with radar systems.
This is achieved by various methods:
●
Verify that the channel is free of any radar signals before using it.
●
Continuous monitoring for radar signals once a channel is in use. The channel
needs to be vacated if a radar signal is detected.
●
Blacklisting channels where a radar signal was detected.
●
Using channels equally (Uniform Loading).
●
Transmit only the required amount of power (Transmit Power Control).
Welcome to the R&S Pulse Sequencer (DFS)
Pulse Sequencer (DFS) key features
R&S
Most radar systems in these bands are used by the military and their actual signatures
are confidential. The representative test patterns therefore contain random variations.
The specifications require that WLAN devices not only detect a specific pattern but
also respond to a wider variety of signals.
Different standards documents exist worldwide that define requirements and test patterns. An overview is provided in Appendix, "DFS Standards and References".
Installation
You can find detailed installation instructions in the delivery of the option or in Chap-
ter 2.2, "Installing the software", on page 10.

3 About the R&S Pulse Sequencer (DFS)
The R&S Pulse Sequencer (DFS) comes as a stand-alone PC-based software with
pre-configured project files for various DFS standards.
Test setup
A typical setup includes a PC with installed software and a connected signal generator.
An example of a simplified test setup is shown on Figure 3-1.
You find the detailed requirements for the various standards in the related standard
documents. See also Chapter 3.1, "Normative reference", on page 24.
About the R&S Pulse Sequencer (DFS)
Figure 3-1: Simplified test setup for conducted DFS tests (Example with R&S SMW)
The setup uses a master device as
link. The test signal is attenuated by an additional 30 dB in the RF path to the client
device. This ensures that only the master device responds to the test signal.
The R&S Pulse Sequencer (DFS) calculates the test patterns and transfers them to the
signal generator. The signal generator injects the DFS test signal into the communication between the master and the client device. The spectrum analyzer is operated in
zero span mode on the channel center frequency. It monitors the traffic between the
two devices and the injected radar pulses. Both, the signal generator and the spectrum
analyzer can be remote controlled by a PC software for test automation.
Consider to trigger the spectrum analyzer sweep when a new radar test signal is injected. A suitable trigger source is one of the markers signals contained in the generated
DFS test patterns.
If the signal levels are high enough an alternative method for the measurement of the
RF test signals or the data traffic is the use of the R&S®NRP-Z81 Power Sensor. The
Figure 3-2 shows a measurement of the FCC Type 1 pulse train generated by a signal
generator. Marker 1 is used as external trigger for the power sensor. This signal marks
the end of the entire burst.

About the R&S Pulse Sequencer (DFS)
Figure 3-3: Example of a report file ("Type > Plugin")
This reporting function is tailored for the DFS testing. It uses a Microsoft Excel
plug-in, that is included in the repository. During waveform generation, the
R&S Pulse Sequencer (DFS) sends all relevant parameters to the plugin and populates the spread sheet.
See also Chapter 4.2, "How to create test reports", on page 29.

ASCII text files
The reporting uses a predefined but editable template. Generated is an ASCII text
file where data is formatted in columns, including header description.

The provided templates can be modified. For detailed description of the file formats,
the template and the plugin, see the R&S Pulse Sequencer user manual.
Status information on whether report logging is enabled or not is displayed in the "Scenario" dialog, see Figure 4-1.
Embedded marker signals
The generated waveforms contain two predefined marker signals:
●
Marker 1
A short marker that marks the end of the last pulse, i.e. the end of the waveform.
The rising edge of this signal marks the measurements start point, e.g. in Channel
Move Time measurements.
●
Marker 2
Marks the individual pulses
This signal can be used to trigger a spectrum analyzer, e.g. for pulse train verification measurements in zero span mode.
An overview information on the marker signals is displayed in the "Comment" field of
each test scenario, see Figure 4-1.
About the R&S Pulse Sequencer (DFS)
Normative reference
Marker signals are output at the corresponding BNC connectors of the
Rohde&Schwarz signal generator. In the R&S SMW for example, these signals are
routed per default to the [USER 1/2] and to the [T/M 2/3] connectors. You can use
these signals to synchronize or to trigger connected spectrum analyzers or power sensors. For examples, see Figure 3-1 and Figure 3-2.
3.1 Normative reference
The DFS testing is subject of the standards listed in Appendix, "DFS Standards and
References".
The software provides the required test patterns for the following standards:

A.2.1.2 Radar type 5
Radar type 5 is a waveform that uses FM chirped bursts. Several pulse parameters
vary randomly. The overall duration of the waveform is 12 seconds. The time is divided
equally, depending on the number of used bursts. Each burst starts at a random
moment within its time interval. The following parameters are selected randomly per
burst and applied to all pulses belonging to same burst.
●
Number of pulses
●
FM chirp deviation
The same applies for the PRI, with the exception that bursts containing three pulses
also vary the PRI within the burst. In this case, the intra-pulse spacing is different
between pulse one and two as well as between pulse two and three.
The parameters for the waveform of type 5 are listed in Table A-9.

A.2.1.3 Radar type 6
Radar type 6 is a waveform that consists of 9 consecutive pulses on one frequency.
This burst is referred to as the pulses per hop.
A total of 100 frequencies are selected from a range 5.25 GHz to 5.724 GHz. The frequency changes every 3 ms and each burst of 9 pulses uses a unique frequency. It
must be ensured that at least one of the random frequencies falls into the receiver
bandwidth of the DUT.

Simulated frequency hopping
The FCC 06-96 Radar type 6 waveform uses a static pattern but requires frequency
hops across a wide frequency range. A real frequency hopping is a demanding implementation, that would, for example, require a vector signal generator with large bandwidth or a fast hopping synthesizer. As an alternative, the standard proposes a method
called simulated hopping. DUTs are devices that receive RF signals in a limited RF
band. Therefore, it is allowed to simulate only the subset of random frequency hops,
that would fall within the DUT's bandwidth.
The principle of the simulated hopping is illustrated on Figure A-1.
Overview of the test requirements and provided test patterns
FCC
Figure A-1: Principle of simulated hopping (according to FCC 06-96)
fc = center frequency
BW = DUT's bandwidth
black dots = hops that are outside the DUT's bandwidth
blue dots = hops that are within the DUT's bandwidth
If simulated hopping is used, generated are only pulses with frequency f
that fulfill
hop
the equation:
(fc - BW/2) < f
< (fc - BW/2)
hop
For the example on Figure A-1, generated are the six blue hops that are within the
DUT's bandwidth.
In the R&S Pulse Sequencer (DFS), the DUT's receiver bandwidth and center frequency are configurable parameters. The frequency hopping is described with the predefined IPM profile "Type 6, Hopping".
During waveform generation, the software selects random frequencies, lists all frequencies in the reporting file and then selects and marks those frequencies that are
within the selected DUT bandwidth.
See also "To set the DUT's frequency and bandwidth for FCC 06-96 type 6 tests with
simulated hopping" on page 36.
