I am working with an 8560E spectrum analyzer with tracking generator.
?
I understand the tracking generator calibration when doing e..g a THRU calibration is stored in trace B.
?
I am able to save trace B after such a calibration to a controller from an 8560E.? ?Data looks like what is on the screen for trace B.
?
I can write trace B back to the instrument -- and it looks fine.
But I cannot get normalization to turn on.? ?I've tried a number of sequences, such as:
?
? ? sa.preset()
? ? sa.start_frequency = band.start_frequency
? ? sa.stop_frequency = band.stop_frequency
? ? sa.write_trace(calibration, which='B')
? ? sa.normalize = True
? ? sa.sweep_coupling = "SR"
? ? sa.source_power = True
?
?
(The parameters are the same as when the calibration was done.)
?
This results is Err 902? (Bad Norm) and Err 903 (A >? DLMT).? ?
?
Does anyone know if this is even possible?
?
(I do understand that I can store the thru calibration into a state register -- if i could figure out how to save and restore that state register, I could probably make that? work.)
?
Thank you!
