    I have to test a 144/28 mhz rx-converter with SA44B and TG44A
    but I don’t find in Spike an Offset frequency function for the tracking generator. How you do ?
    Thanks

    Hi Ermy,

    We do not have a frequency offset setting for the TG in our software. I apologize for the inconvenience.

    Regards,
    Andrew

    If an approximate conversion loss (+/- 3 dB) is acceptable, you can sweep the output range with the SA44B, and then step across the input range with the TG manual controls, using MAX HOLD on a trace.

    For better accuracy, an RF power meter could be used to measure the actual TG output power at each frequency and you could subtract this from the SA44B’s reading.

    Andrew thanks for the reply and also Justin’s suggestion.
    I found, however, that the function is available in the 2.18B version of the legacy software.
    I’d like to see it in an upcoming release also in Spike.
    Thank you all
