4 Measurement Operations & Settings
example: sens1:pow:rang:auto? -> 1<END>
affects: All power meters and return loss modules
dual sensors: Can only be sent to master channel, slave channel parameters are identical.
command: :SENSe[n]:[CHANnel[m]]:POWer:REFerence
syntax: :SENSe[n]:[CHANnel[m]]:POWer:REFerence<wsp>
TOMODule|TOREF,<value>PW|NW|UW|MW|Watt|DBM|DB|MDB
description: Sets the sensor reference value.
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]:[CHANnel[m]]:POWer:REFerence:STATe:RATio on page 114, the instrument uses the last
reference value entered for the selected reference mode.
response: none
example: sens1:pow:ref tomod,-40DB
affects: All power meters
dual sensors: Master and slave channels are independent.
command: :SENSe[n]:[CHANnel[m]]:POWer:REFerence?
syntax: :SENSe[n]:[CHANnel[m]]:POWer:REFerence?<wsp>TOMODule|TOREF
description: Returns the sensor reference value.
parameters: TOMODule:
TOREF:
Returns the reference value in dB used if you choose measurement relative to another channel
Returns the reference value in Watts or dBm if you choose measurement relative to a constant
reference value
response: The reference as a float value.
