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 mod ules.
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 a nd does
not need a tri ggering comm and.
NOTE The power meters must be runnin g for this command to be effec tive.
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 page26 for more informatio n 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 firmwa re or later).
dual sensors: Mast er channels receive a read comm and, 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 p age 87.
