Hi Volker,
Thanks for the feedback.
We have disabled the measurement for the SA44/124 devices due to their lack of hardware image rejection. The wideband noise source aliases in at all points in the measurement affecting the results. We have not determined if we will address this.
We intend to revisit this measurement in the future. Reusing the noise source measurements (step 1/2) is something we plan on adding. We agree that it would be beneficial to not need to perform this step for each measurement.
We have also considered how we would perform more automation with the noise source. The trigger idea is good.
We can review the noisy values you are seeing. With some more testing we might be able to reproduce and deal with these. Can you provide any configuration information for the measurements on which you saw this issue? I will include this in my notes.
Can you clarify your last question?
Thanks again for the feedback. This will be very useful for future development. We are happy this measurement has been useful for you. Hopefully we can make it better in future revisions.
Regards,
Andrew
