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 MHzLimit File:
249.9,-200
249.9995,-200
250,24
250.0005,-200
250.1,-200I 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

You got me !
I was doing some amplitude sweeps in zero span and thought about
doing exactly what you described in sweep mode…Since I have a network analyser in here there is no real need to do it with the SA44B ( besides documentation that is much more easy than with the good old R&S ).
I also have one of your VSG. What is the reason this one cannot be used as tracking source ?
