Hi Andrew,

thanks for your immediate support. I thought that this is working like you explained, but I still cannot get it running.

I would like to switch to a more simple to replay example:
– Single carrier 250 MHz

Limit File:
249.9,-200
249.9995,-200
250,24
250.0005,-200
250.1,-200

I used limit line 3.
Setting to Lower Bound will always pass.
Setting to Upper Bound will always fail.

No matter what the aplitude is. Increasing RBW does also not solve the problem.

Two more problems that I would put on the bug list:
– it is not possible to enter these values in the application, since rounding of the frequency will happen. It has to be done in a text editor and you have to load it. Still you cannot view it because of roundings…
– Changes to the limit lines will not always reflect to the app. Sometimes you will have to switch on and off or switch to another line. I have not found any system behind this behavior.

Best

Volker
