N5181B  Measure Power in LIST mode

Good hey,

I'm currently having an issue measuring power in LIST mode

as follows the routine of SCPI i follow and the result output i get and what i'm expecting to receive

1. *RST
2. SWE:POIN 11
3. SWE:DWEL 1.5
4. POW:MODE LIST
5. POW:STAR 0
6. POW:STOP 10
7. INIT:CONT ON

after running this sequence of commands the display will now step through the power from 0-10 dBm

however the result from using the "POW:AMPL?" query will return -1.44E+002 (-144)

I'm expecting the output to return somewhere within the range of 0,+10

Firmware version B.01.65

If this is not the correct procedure please give some guidance on how to proceed

Regards

John
