Objet?: [HP-Agilent-Keysight-equipment] 8560E: Restoring THRU calibration from a controller

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!
