FETCh Subsystem Commands
This section provides the description of the following commands.
Command: :FETCh[n]:POWer?
Syntax: :FETCh[n]:POWer?
Description: Reads the current power meter value. It does not provide its own triggering and so must be used with either continuous
software triggering or a directly preceding immediate software trigger.
It returns the value the previous software trigger measured. Any subsequent FETCh command will return the same value, if
there is no subsequent software trigger.
Parameters: None
Response: The current value 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.
Example: fetc1:pow? -> +6.73370400E-04
Affects: N7744C and N7745C
Command: :FETCh[n]:POWer:ALL?
Syntax: :FETCh[n]:POWer:ALL?
Description: Reads all current power meter values. It does not provide its own triggering and so must be used with either continuous
software triggering or a directly preceding immediate software trigger.
It returns the value the previous software trigger measured. Any subsequent FETCh command will return the same value, if
there is no subsequent software trigger.
Parameters: None
Response: 4-byte Intel float values in a binary block in Intel byte order. The values are ordered by slot.
Data values are always in Watt.
Example: fetc:pow:all? -> interpreted as
+1.33555600E-006|+1.34789100E-006|+1.37456900E-006
Affects: N7744C and N7745C
