SigIQPro Signal Generation Software

SigIQPro is Siglent’s custom signal development software. Signals can be created and loaded directly to IQ generating baseband generators that are stand alone or within RF signal sources. The latest version of the PC software can be downloaded from the SigIQPro product page here.

You can learn more about SigIQPro by downloading the user's guide here.

The current version at the time of this article is 2.0.0.2.9R1 and includes the following file type options:

You can download the latest version from here.

The SigIQPro software offers a number of free options for evaluation and testing with a signal generator. The toolkit section allows for import of CSV, MAT, or DAT files directly as IQ data. This is ideal for import and upload of custom signals engineers have created in other tools. This feature is permanently free and can be used without restriction: 

Furthermore, the Custom IQ signal types can be used for free permanently with a Siglent RF signal generator. This includes definitions for all of the types of signals that are available from the instrument front panel with additional customizations available. Specifically, the SigIQPro interface can simplify the loading of custom data files and customized constellation definitions:

All other signal types from the option list above can be built and loaded from here as well. Each of these will create and upload 30 separate binary files to a specific serial number for free. After 30 files have been created and loaded to a specific instrument, engineers require the appropriate SigIQPro license for that type of signal. 

Licenses are tied to the instrument, so once an instrument SigIQPro license is purchased, signals can be loaded to that instrument from any number of PCs that may connect to that instrument with the software configured. This license toolkit facilitates engineering evaluations of signals and software, and in many cases, supports long term use without additional cost. Dynamic generation of custom signals over time requires the additional license purchase.

New signal types have significant customization and configuration requirements. Utilize these free trials to test the configuration capabilities of the software or generate signals in some other toolkit and import using the standardized tools.

And here is the resulting waveform in real-time:

SigIQPro provides a software platform for customizing and
delivering complex signals to a RF signal generator. Standard custom IQ waveforms and the ability to import additional waveforms is free permanently. The software adds free trials for additional signal manipulation of each optional type. All of these included capabilities make SigIQPro an excellent signal evaluation and verification toolkit when partnered with a Siglent RF signal source.
