I got demo E5072A unit and i am trying to measure Intermod using the macrom posted on Key sigh (E5072AIMDWizard_0101).
The problem I have that the sweep option are disabled.What I am missing on that ENA?
The macro stated that it required option 008 (frequency offset). I see that the unit do have frequency offset.
I try manually set that measurement too but i do not see place where I can level the external signal generator (i see oll the setting for the generator and the ENA looks lieke it detecting it over Keithley USB- GPIB controller.
I also try the harmonics measurement macro (part of E5072AAmplifierWizard_0101), however when tray to use USB U2000 Power Sensor I getting message to start Keysight Connection Expert. I did that and the Connection Expert did detect the Power Sensor but the Macro always showing the same message.
Anybody from Keysight have some insight how to set that measurement properly or do I need to enable some additional options?

I finally get to the conclusion that the problem is that both macros (IMD and Amplifier wizard) for ENA E5072A do not control the USB power sensor (I used U2000A).
In Power Meter configuration it do show the sensor serial number however when try to check connection nothing happen.
When I trying to power level I am getting message " Pleas boot Agilent Connection Expert". I did loaded the Keysight Connection Expert 17.1 and it detecting the USB Power Sensor with out any problem. There is no problem to use USB Power Sensor in ENA E5072A if I used the firmware configuration source power leveling.
I also try Power Meter that use GPIB (E4418B) no problem with detecting and leveling thru Macro or the firmware. ).
By the way I try to run macro for ENA E5071C (amp wizard) to set compression, and there is no problem with controlling USB Power Sensor.
So the bug only apply to the macros on E5072A.
Any body from Keysight is so kind to help fix that bug in the ENA E5072A macros.
I also see couple procedure for IMD that can be little improve.
1. Use B receiver to level the Port 1 and the generator (it is already calibrated in first step so why not use that as power meter, that especially useful for high power measurement).
2. Add dynamic RX leveling thru B Receiver (as you have that in PNA-X) for the IMD macro. Current IMD macro is not particularly good if you measure monolithic amplifiers as they have big gain slop. In such case, If you use fix input power you will very quickly realize that the analyzer do not have enough dynamic range, and you need to repeat the measurement for many frequency ranges. The standard procedure is to level power output of DUT to fix power using the receiver and then measure the IMD.
Again, any word from KeySight representatives? Any possible solution for that USB power sensor macro bug?
