Programming Commands
CALCulate3 Subsystem
DELTa:POWer[:STATe]
Turns the delta-power measurement mode on and off.
Syntax
:CALCulate3:DELTa:POWer[:STATe]{?| {ON | OFF | 1 | 0}}
Attribute Summary Preset State: off
*RST State: off
SCPI Compliance: instrument specific
Description When this state is on, the power of the reference laser line is subtracted from the
power values of all laser lines except the reference.
The power data returned by the CALC3:DATA? query is the array of laser line
power levels normalized to the power level of the reference laser line. The power of
the reference laser line is returned as an absolute power (unnormalized). The fre-
quency data returned is the array of absolute frequency values.
DELTa:PRESet
Turns off all delta measurement states.
Syntax
:CALCulate3:DELTa:PRESet
Attribute Summary Preset State: not affected
*RST State: not affected
SCPI Compliance: instrument specific
Command Only
Note
Only one STATe command can be turned on at any one time. Attempting to turn
more than one state on at a time results in a “–221 Settings Conflict” error.
Refer to “Measure delta, drift and signal-to-noise” on page 94 for additional
information on selecting measurements.
