Measurement Operations & Settings
4
Parameters:
TOMODule:
TOREF:
Sets the reference value in dB used if you choose measurement relative to another
channel
Sets the reference value in Watts or dBm if you choose measurement relative to a
constant reference value
The reference as a float value.
You must append a unit type
•
dB if you use TOMODule or
•
Watts or dBm if you use TOREF.
The two reference values are completely independent. When you change the reference mode using the command
:SENSe[n]:POWer:REFerence:STATe:RATio, the instrument uses the last reference value entered for the selected reference
mode.
Response:
None
Example:
:sens1:pow:ref tomod,-40DB
