Measurement Functions – The SENSe Subsystem Measurement Operations & Settings
Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition 89
command:
:INITiate[n]:[CHANnel[m]]:CONTinuous?
syntax: :INITiate[n]:[CHANnel[m]]:CONTinuous?
description:
Queries whether the software trigger system operates continuously or not
parameters: none
response: A boolean value: 0 or OFF: measurement is not continuous
1 or ON: measurement is continuous
example: init2:cont? → 1<END>
affects: All power meters, return loss modules.
dual sensors: Can only be sent to master channel, slave channel parameters are identical.
command:
:READ[n][:CHANnel[m]][SCALar:]:POWer:ALL?
syntax: :READ[n]:[CHANnel[m]]:POWer:[:DC]:ALL?
description: Reads all available power meter channels. It provides its own software triggering and does
not need a triggering command.
NOTE The power meters must be running for this command to be effective.
parameters: none
response: 4-byte Intel float values in a binary block in Intel byte order. The values are ordered by slot
and channel order.
See “Data Types” on page 26 for more information on Binary Blocks.
NOTE Data values are always in Watt.
example: read1:pow:all? → interpreted as
+1.33555600E-006|+1.34789100E-006|+1.37456900E-006<END>
affects: All power meters (v3.0x firmware or later).
dual sensors: Master channels receive a read command, see:
“:READ[n][:CHANnel[m]][:SCALar]:POWer[:DC]?” on page 90
Slave channels receive a fetch command, see:
“:FETCh[n][:CHANnel[m]][:SCAlar]:POWer[:DC]?” on page 87.
