Hi Andrew,
in the release notes from 3.8.0 you wrote:

I have tried but could not get the expected result.
Parameter 1 delivers IQ Values that can be used with this formular: 10*log10(mean(I^2 + Q^2))
Parameter 2 delivers the number of IQ values
looks like no other paramters are implemented.
Can you please explain how FETCH:ZS? retrieves the avg power value in zero span mode.
