4 Measurement Operations & Settings
Command: :FETCh[n]:POWer:ALL:CSV?
Syntax: :FETCh[n]:POWer:ALL:CSV?
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: String containing the power values from each available channel in a comma separated format.
Data values are always in Watt.
Example: fetc:pow:all:CSV? " -> +1.33555600E-06, +1.34789100E-06, +1.37456900E-06"
Affects: N7744C and N7745C
Command: :FETCh[n]:POWer:ALL:CONFig?
Syntax: :FETCh[n]:POWer: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: fetc:pow:all:conf? interpreted as 1|1|2|1|3|1|4|1
This 16-byte block means that there are four powermeters present:
Slot 1, Channel 1
Slot 2, Channel 1
Slot 3, Channel 1
Slot 4, Channel 1
Affects: N7744C and N7745C
Command: :FETCh[n]:POWer:MAX?
Syntax: :FETCh[n]:POWer:MAX?
Description: Returns the maximum power value since the reset.
Parameters: None
