CALCulate3 Subsystem
DELTa:REFerence:FREQuency
Selects the reference laser line for DELTa calculations.
Syntax
:CALCulate3:DELTa:REFerence:FREQuency{?| {<real> | MINimum | MAXimum}}
<real> is a frequency value that is within the following limits:
Constant
Description
MINimum 181.6924 THz
MAXimum 236.0571 THz
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 fre-
quency entered. Subsequent measurements will use the frequency clos-
est 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.
DELTa:REFerence:POWer?
Queries the reference laser line’s power level.
