Simplify Custom Signal Creation

Keysight PathWave Signal Generation (PWSG) Advanced Waveform Utility (AWU) is a flexible signal creation tool that reduces time spent on signal simulation. PWSG AWU is part of PWSG Desktop. It can work with different waveform files with Keysight Signal Generators and Arbitrary Waveform Generators, provide with easy-to-use user interface, and generate signals with wideband correction for measurements quickly and easily.

• PWSG AWU is running on PC, which can create and download generated waveforms into Keysight signal generators

The required license is:

• Essential features require no license

• Premium features require N7618APPC license on PC

Adjust waveform sample rate (essential)

PWSG AWU enables you to specify the sample rate and download all customized waveform files without time-consuming conversions. PWSG AWU automatically re-samples the waveform with the specified sample rate or resampling ratio, which can be a fractional number. The process is designed to preserve the waveform shape and minimize distortion at the endpoints.

Experiment for 6G using existing radio formats with time scale factor (essential)

PWSG AWU enables you to specify the bandwidth multiplier by adjusting Time Scale Factor under Waveform block. This provides a handy way to generate very wideband waveform using existing radio formats, such as 5G NR, to experiment 6G before standard is established. Time Scale Factor can be set between 0.001 to 1000. It overrides the sample rate in the waveform to playback the waveform faster or slower, without changing IQ data.

Support SCPI programming (essential)

PWSG AWU supports SCPI programming. You can control the instrument via sending SCPI commands.Supported IO interfaces include HiSLIP, Sockets and VXI-11/SICL. You can easily program with Python using PyVISA or Socket to send SCPI commands. The example below shows a sample Python code for exporting waveform.
