dear all,

i have 4402B spectrum analyzer with option 290 (to be comatable with model 8591 commands). but i have a problem with only one command which is related to the input impedance 50 or 75 Ohm.

i tried to use INZ 50 and INZ 75 but does not work as 8591 analyzer.

could you please help me to enter a proper commands??

Thanksssss in advance for your help and support....

For 4402B the command to change the Input Impedance Corrections that are used is:

[:SENSe]:CORRection:IMPedance[:INPut][:MAGNitude] <number>

50 or 75 are the accepted values, you can also query this value

[:SENSe]:CORRection:IMPedance[:INPut][:MAGNitude]?

Best regards,
