SYSTem:CALibrationFile?
Usage: SYST:CALF? 0
Description: Retrieves the name of the calibration file.
Because this command is used for other Luna systems, the
user must specify zero (0) with this command to retrieve
the calibration filename.
Response: Returns the name of the calibration file currently in use.
SYST:SAT?
Usage: SYST:SAT?
Description: Queries whether the detectors were saturated during the
previous scan. It is analogous to the “Detectors saturated,

Returns 1 if the detectors were saturated, or 0 if the detectors

mode Scan button.
Example: SYST:SAT?
This query returns the value 1 or 0, depending on whether
the detectors were saturated or not.
