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 428.6 THz
Attribute
Summary
Preset
State: 428.6 THz (700 nm)
*RST State:428.6 THz (700 nm)
SCPI Compliance: instrument specific
Description
The reference will be the laser line at the frequency closest to the frequency
entered. Subsequent measurements will use the frequency closest to the ref-
erence 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.
