Communication Analyser

[Patrick Collins]

Good afternoon,

Would the Radioberry and AD9866 be a good basis for a low cost HF communication analyser with the addition of a dummy load, power meter and variable attenuator.

Very respectfully,

Paddy

Yes, I think so. You have a RF generator and Receiver so a VNA is possible with the correct software.

The downside is the limited bandwidth. Tools like Nanovna, TinySA have huge bandwidth and are low cost.

You can add some mixers but that increases cost.

You can add return bridge and other options, but it will be quite a software project.

You can look at https://www.albfer.com/en/2020/02/21/satsagen-2/  this is a project for the Adalm pluto

73,

Paul
