MEASurement Commands 2
U8480 Series Programming Guide 81
FETCh[1][:SCALar][:POWer:AC]:MUNC? 
[<expected_value>[,<resolution>[,<source list>]]]
This command sets the measurement function, recalculates the measurement and 
the corresponding measurement uncertainty, and places the result on the bus. 
The result is a power-based measurement and is expressed in the units defined by 
UNIT[1]:POWer.
When “UNIT:POW W” is set, the parameters returned will be:
–measured power in Watts
– +measurement uncertainty value in %
– –measurement uncertainty value in % 
When “UNIT:POW DBM” is set, the parameters returned will be:
–measured power in dBm
– +measurement uncertainty value in dB
– –measurement uncertainty value in dB.
