Programming Commands

CALCulate3 Subsystem

 

DELTa:WPOWer[:STATe]

 

Turns the delta wavelength and power measurement mode on and off.

Syntax

:CALCulate3:DELTa:WPOWer[:STATe]{? {ON OFF 1 0}}

Attribute

Preset State: off

Summary

*RST State: off

 

SCPI Compliance: instrument specific

Description

When on, the wavelength of the reference laser line is subtracted from

 

the wavelength values of all laser lines except the reference. The

 

power value of the reference is subtracted from the power values of all

 

laser lines except the reference.

 

For the CALC3:DATA? query, the power data returned is the array of

 

powers normalized to the power of the reference laser line. The power

 

of the reference laser line is returned as an absolute power (unnor-

 

malized).

 

The frequency data is the array of frequency values normalized to the

 

frequency of the reference laser line. The frequency of the reference

 

laser line is returned as an absolute frequency (unnormalized).

 

 

 

 

 

 

 

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 3-14 for additional informa-

 

 

tion on selecting measurements.
