:CALCulate3:DELTa:PRESet
Turns off all delta measurement states.
Attribute Summary
Preset State: not affected
*RST State: not affected
SCPI Compliance: instrument specific
Command Only
:CALCulate3:DELTa:REFerence:FREQuency{?| {<real> | MINimum | MAXimum}}
Selects the reference laser line for DELTa calculations.
<real> is a frequency value that is within the following
limits:
Attribute Summary
Preset
State: 236.0571 THz (1270 nm)
*RST State: 236.0571 THz (1270 nm)
SCPI Compliance: instrument specific
Description
The reference will be the laser line at the frequency
closest to the frequency entered. Subsequent measure-
ments will use the frequency closest to the reference
frequency used for the previous measurement.
The query returns the reference laser line’s frequency.
The default units for the
<real> parameter are Hz.
:CALCulate3:DELTa:REFerence:POWer?
Queries the reference laser line’s power level.

<real>
is a wavelength value that is within the following
limits:
Constant Description
MINimum 181.6924 THz
MAXimum 236.0571 THz
