Measurement Functions – The SENSe Subsystem Measurement Operations & Settings
Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition 105
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 rela-
tive 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.
NOTE
You must append a unit type
• dB if you use TOMODule or
• Watts or dBm if you use TOREF.
NOTE
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 107, 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 rel-
ative to another channel
Returns the reference value in Watts or dBm if you choose measure-
ment relative to a constant reference value
response: The reference as a float value.
example: sens1:pow:ref? toref → +1.00000000E-006<END>
affects: All power meters
dual sensors: Master and slave channels are independent.
