Hi Peter,
Thanks for the feedback and input. The reference offset was moved to the file menu because it is now being used across most measurements in the software, as opposed to just the sweep modes in prior versions of Spike. Rather than have a separate entry for each measurement we put it in a global location. I apologize for the confusion there.
As far as the limitation on disp ref in harmonic measurements, it is an arbitrary limitation that I can remove in the next release. To get around this limitation, you can always simulate what the software is doing with a reference offset. For example, with a 50dBm input and 40dB ref offset (with 40dB atten), you can simply set the input level to (50-40 = +10dBm) and ensure the ref offset is 0. This will ensure the receiver settings are the same as with the ref offset, but then you will have to add 40dB to your measurments…
Regards,
Andrew
