PC software masters complex pulses

Pulse sequencer PC software for R and S signal generators allows users to easily generate libraries of complex pulses and to combine them into pulsetrains.

When performing telecomms or radar testing it is often necessary to generate pulsed signals.

The requirements placed on generating such signals are becoming increasingly stringent, and often involve very complex pulsetrains.

Now, new pulse sequencer PC software for the R and S SMU200A, SMJ100A, AMU200 and AFQ100A signal generators allows users to easily generate libraries of complex pulses and to combine them into pulsetrains.

For use in military applications, proprietary intrapulse modulations can be integrated via a plug-in interface.

The software comes with preconfigured examples for distance measuring equipment (DME), RFID (in line with ISO/IEC14443-2), and DFS (in line with ETSI and FCC).

DFS stands for dynamic frequency selection and describes the requirements placed on WLAN instruments, which have to detect radar signals in the 5GHz frequency range.

Another preconfigured example demonstrates the extensive capabilities of the software to generate radar signals (Barker pulse, nonlinear chirps, echo generation etc).

In addition to time characteristics, envelope, phase, and frequency offset of a pulse, it is also possible to select modulations such as ASK, FSK, BPSK, QPSK, FM chirps, FM or AM.

To simulate technical systems, the user can define different jitters and combine them with pulse parameters.

Up to four marker traces can be user-defined and used for trigger purposes.

The straightforward user interface allows easy compilation of the pulse scenarios as well as the graphical display of the generated data.

The power spectrum and the I/Q density diagram provide useful tools for fast pulsetrain evaluation, particularly the display of the I/Q signals over time.

When it comes to generating many different pulsetrains, the R and S pulse sequencer PC software features an automated batch build function.

By using this function, all individual waveforms are generated and combined on the generator into a multisegment waveform.

It is thus possible to quickly change between the individual signals as required by means of control command.

The new R and S pulse sequencer PC software is now available from Rohde and Schwarz and can be downloaded free of charge for the signal generators of the R and S SMx family as well as for the R and S AMU200A and AFQ100A.
