:SENSe[n]:[CHANnel[m]]:POWer:RANGe:AUTO?
:SENSe[n]:[CHANnel[m]]:POWer:RANGe:AUTO?
Returns whether automatic power ranging is being used by the module.
none
A boolean value: 0: automatic ranging is not being used.
1: automatic ranging is being used.
sens1:pow:rang:auto?
All power meters
Can only be sent to master channel, slave channel parameters are identical.
:SENSe[n]:[CHANnel[m]]:POWer:REFerence
:SENSe[n]:[CHANnel[m]]:POWer:REFerence<wsp>
TOMODule|TOREF,<value>PW|NW|UW|MW|Watt|DBM|DB|MDB
Sets the sensor reference value.
TOMODule: Sets the reference value in dB used if you choose measurement rela-
tive to another channel
TOREF: 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 82, the
instrument uses the last reference value entered for the selected reference mode.
none
sens1:pow:ref tomod,-40DB
All power meters
Master and slave channels are independent.
:SENSe[n]:[CHANnel[m]]:POWer:REFerence?
:SENSe[n]:[CHANnel[m]]:POWer:REFerence?<wsp>TOMODule|TOREF
Returns the sensor reference value.
TOMODule: Returns the reference value in dB used if you choose measurement
relative to another channel
TOREF: Returns the reference value in Watts or dBm if you choose measure-
ment relative to a constant reference value
The reference as a float value.
sens1:pow:ref? toref
All power meters
Master and slave channels are independent.
