hi Signal Hound people,
1) I see the TG124A recommended for use with a mini-circuits coupler and a BB60C as a scalar network analyser.. well, I happen to have the older BB60A, and I was wondering if this setup can work with my BB60A, too?
2) Ideally if I buy a TG to use with my spectrum analyser for antenna analysis, it’d be nice to be able to use it to do immunity stuff, at least till I get around to spending the $$ on a proper signal generator.
In that case, I’d be interested in using the TG with a tekbox TBMDA1 (modulated driving amp)
From what I can see – The TG at max output is -12dBm, so if I run the TG through a 10dB attenuator, then into this, I’ll be able to get myself a signal from 40M to 3G, at 0dBm down to -18dBm (with 1k AM applied or not, via switch control on the amp) which I can then run into another bigger power amp that likes 0dBm input, to punch the signal out much bigger.
Do you expect any issues that I’d have here if I was using a standard frequency scan from the Spike software (or my own software, using the API) as a basic immunity scan source? the result doesn’t have to be perfect, but it’d be nice if it was at least a bit useful for pre-compliance purposes.

The BB60A will need firmware version 5 to be compatible. You can download it here: https://signalhound.com/support/product-downloads/bb60c-bb60a-downloads/
The TG124A being used as a standalone generator, and amplified/modulated appropriately, should probably work for immunity testing. Depending on your needs, you may wish to low pass filter the TG output as it tends to have higher harmonics than a dedicated signal generator. You would probably want to automate it using our TG standalone API, which you can get from https://signalhound.com/products/usb-tg124a/
