Measurement Operations & Settings Measurement Functions – The SENSe Subsystem
104 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
command:
:SENSe[n]:[CHANnel[m]]:POWer:RANGe:MONitor[:UPPer]?
syntax: :SENSe[n]:[CHANnel[m]]:POWer:RANGe[:UPPer]?
description: Sets the power range for a retun loss module’s monitor diode.
parameters: none
response: The range setting as a float value in dBm
(−110 ≤ value ≤ +30).
example: sens1:pow:rang? → -2.00000000E+001<END>
affects: All return loss modules.
dual sensors: Master and slave channels are independent.
command:
:SENSe[n]:[CHANnel[m]]:POWer:RANGe:AUTO
syntax: SENSe[n]:[CHANnel[m]]:POWer:RANGe:AUTO <wsp><boolean>
description: 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.
parameters: A boolean value: 0 or OFF: automatic ranging disabled
1 or ON: automatic ranging enabled
response: none
example: sens1:pow:rang:auto 1
affects: All power meters and return loss modules
NOTE
For return loss modules, affects return loss diode and monitor diode simultaneously.
dual sensors: Can only be sent to master channel, slave channel is also affected.
command:
:SENSe[n]:[CHANnel[m]]:POWer:RANGe:AUTO?
syntax: :SENSe[n]:[CHANnel[m]]:POWer:RANGe:AUTO?
description: Returns whether automatic power ranging is being used by the module.
parameters: none
response: A boolean value: 0: automatic ranging is not being used.
1: automatic ranging is being used.
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.
