108 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
command:
:SENSe[n]:[CHANnel[m]]:POWer:UNIT
syntax: :SENSe[n]:[CHANnel[m]]:POWer:UNIT<wsp>DBM|0|Watt|1
description: Sets the sensor power unit
parameters: An integer value: 0: dBm
1: Watt
or DBM or Watt
response: none
example: sens1:pow:unit 1
affects: All power meters
dual sensors: Master and slave channels are independent.
command:
:SENSe[n]:[CHANnel[m]]:POWer:UNIT?
syntax: :SENSe[n]:[CHANnel[m]]:POWer:UNIT?
description: Inquires the current sensor power unit
parameters: none
response: An integer value: 0: Current power units are dBm.
1: Current power units are Watts.
example: sens1:pow:unit? → +1<END>
affects: All power meters
dual sensors: Master and slave channels are independent.
command:
:SENSe[n]:[CHANnel[m]]:POWer:WAVelength
syntax: :SENSe[n]:[CHANnel[m]]:POWer:WAVelength<wsp><value>|MIN|MAX|DEF
[PM|NM|UM|MM|M]
description: Sets the sensor wavelength.
parameters: The wavelength as a float value in meters.
Also allowed are: MIN: minimum programmable value
MAX: maximum programmable value
DEF: This is not the preset (*RST) default value but is half
the sum of, the minimum programmable value and the
maximum programmable value
response: none
example: sens1:pow:wav 1550nm
affects: All power meters
dual sensors: Master and slave channels are independent.
