:SENSe[n]:[CHANnel[m]]:POWer:RANGe:AUTO
SENSe[n]:[CHANnel[m]]:POWer:RANGe:AUTO <wsp><boolean>
Enables or disables automatic power ranging for the module.
If automatic power ranging is enabled, ranging is automatically determined by the instru-
ment. Otherwise, it must be set by the sensn:pow:rang command.
A boolean value:
none
sens1:pow:rang:auto 1
All power meters
Can only be sent to master channel, slave channel is also affected.
: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:
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 87, 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.
Measurement Operations & Settings
0 or OFF: automatic ranging disabled
1 or ON: automatic ranging enabled
0: automatic ranging is not being used.
1: automatic ranging is being used.
