Using scpi with E4440A spectrum analyzer

Question asked by kazoitzik on Jul 22, 2019



I made a c# program using scpi protocol that controls  signal generators, noise figure analyzers and spectrum. My program worked *well* with other types of spectrums but not with the E4440A. 


The spectrum gets into remote mode, but not respond to any scpi command. I tried to commuincte with the spectrum using keysight command expert and got this message;


COMException:AgilentSAn: IVI Instrument Class not supported by instrument. AgilentSAnSA:Personality is not installed.


How can i fix that?

Thank you
