Measurement Operations & Settings
command:
:READ[n][:CHANnel[m]]:POWer:ALL:CONFig?
syntax:
:READ[n]:[CHANnel[m]]:POWer[:DC]:ALL:CONFig?
description:
Returns the slot and channel numbers for all available power meter channels.
Use this command to match returned power values to the appropriate slot and channel number.
parameters:
none
response:
A binary block (Intel byte order) consisting of 2-byte unsigned integer value pairs (so each pair has 4 bytes). The first
member of the pair represents the the slot number, the second member of the pair represents the channel number.
example:
read1:pow:all:conf?
1|1|1|2|12|1<END>
This 12-byte block means that there are three powermeters present:
Slot 1, Channel 1
Slot 1, Channel 2
Slot 12, Channel 1
affects:
All power meters (v3.0x firmware or later).

command:
:READ[n][:CHANnel[m]][:SCALar]:POWer[:DC]?
syntax:
:READ[n]:[CHANnel[m]][:SCALar]:POWer[:DC]?
description:
Reads the current power meter value, or for a return loss module the power value at the return loss diode (back reflection
path). It provides its own software triggering and does not need a triggering command.
If the software trigger system operates continuously (see
page 91), this command is identical to
If the software trigger system does not operate continuously, this command is identical to generating a software trigger
:INITiate[n]:[CHANnel[m]][:IMMediate]
(
The power meter must be running for this command to be effective.
parameters:
none
response:
The current power meter reading as a float value in dBm, W or dB.
If the reference state is absolute, units are dBm or W.
If the reference state is relative, units are dB.
