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 num-

 

ber.

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? → interpreted as

 

1112121<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).

dual sensors:

 

 

 

command:

syntax:

description:

N O T E

parameters:

response:

N O T E

example:

affects:

dual sensors:

:READ[n][:CHANnel[m]][:SCALar]:POWer[:DC]?

:READ[n]:[CHANnel[m]][:SCALar]:POWer[:DC]?

Reads the current power meter value, or for a return loss module the power value at the re- turn 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

“:INITiate[n]:[CHANnel[m]]:CONTinuous?” on page 89), this command is identical to “:FETCh[n][:CHANnel[m]][:SCAlar]:POWer[:DC]?” on page 87.

If the software trigger system does not operate continuously, this command is identical to generating a software trigger (“:INITiate[n]:[CHANnel[m]][:IMMediate]” on page 88) and then reading the power meter value.

The power meter must be running for this command to be effective.

none

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.

read1:pow? → +1.33555600E-006<END>

All power meters and return loss modules and attenuator with power control

Can only be sent to master channel, slave channel is also triggered.

To read a simultaneous result from the slave channel, send

“:FETCh[n][:CHANnel[m]][:SCAlar]:POWer[:DC]?” on page 87 directly after this command.
