Spectrum Analyzer With Tracking Generator

[jesmitter]

I need to characterize a low frequency filter. Is there and application or app note that can show how to turn Red Pitaya into a spectrum analyzer with an internal tracking generator?

Thanks,

Sounds very similar to what my Vector Network Analyzer does:

Could you have a look at it and tell me what is missing for characterization of a filter?

The Vector Network Analyzer application can be installed via the Red Pitaya application marketplace:
