Having trouble determining the proper sequence of SCPI commands to execute calibration measurement (input/output) jumper cables in ERTA mode.
Having trouble determining the proper sequence of SCPI commands to execute calibration measurement (input/output) jumper cables in ERTA mode.
I took a closer look at the SCPI help file and you can load srcside cable and rcvrside cable corrections, these would be the input and output jumper cables.

So the solution is to measure the cables in NA mode as S21 and save those cables' data as csv and recall in ERTA mode. Please note that the basic measure jumper cable in ERTA mode uses 201 points over the full frequency range of the analyzer (whatever that is), whereas in NA mode you have the option of setting up the frequency and points to match your setup. So actually using NA mode to characterize your cables provides you a more accurate solution compared to the ERTA jumper cable setup. A 2-port Cal is a good idea also. ERTA uses the default CalReady, which is also 2-port. But a user-performed 2-port with the exact stimulus is a better measurement.
I only mention the difference between the setups in case you are trying to match the manual front panel measurements to SCPI, be aware of what the measurement is doing.
In ERTA, with the front panel, you can load the NA mode files too, but if you follow the Guided Wizard, it uses 201 points over the full-band of the analyzer.
