    Tone injection testRecord & plot

    Inject a tone, record and verify that the tone appears in baseband at the correct location. This should be done for all 4 EHT bands.

    For doing a test recording a plotting the resulting spectrum in both polarizations do:

    log into the corresponding recorder e.g. recorder1

    ...

    This will do a short test recording
