Hi Justin,
I fully agree that a “store thru” is difficult and in my mind makes no sense. I would disable it if an offset entered and display dBm values.

On multiplier you have anyhow a lowpass filter on the input and in most cases an amplifier to lift -10 dBm up. So I think there is no harm in this.

Hi A.J.,
Some hints to consider on Tracking Generator functions (in case you change it):
# Allow an offset e.g. 10.7 MHz to test mixers
# or allow to add a LO frequency with a sign to test also converter with LO = RF+IF e.g. on LO >= 0: RFtrack = LO +RFin; on LO < 0: RFtrack = LO -RFin. You could reuse the frequency field on TG.
# Allow tracking generator to run at a fraction of RF-in to test frequency multiplier e.g. RFin = RFtrack * n (n = {1,2,3,4 …})
# Use up and down arrows like in Frequency (control) instead of large “Step up” and “Step down” Buttons
# Add an “RF on” tick box

Hello Signalhound Team,
Just got my Spike/SG124/TG124 up and running. It is quite a easy to use program, however as a fresh one I like to give you some feedback:

In sweep mode:
There is on way to RF on/off the Tracking generator. Also Spike does not check if TG settings are realy set e.g. I got no RF output and 10 MHz-Reference settings did not function. I verifyed this with my osciloscope. The old TG-Standalone SW gave me a hint and after USB disconnect and reconnect everything worked.

In Scalar Network Analysis mode:
– Tracking Generator Controls: Center Freq and Freq Step Up/Down should be disabled as Frequency (Controls) has the lead.
– Amplitude (Control): Ref Level units should change to dB, linear (V) and not keep dBm.

Regards
Guenther
