Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
The LASER:CAL:DEFAULT command sets all of the laser calibration constants to default values.
None.
This command should only be used in the case in which the calibration has become corrupted and
circumstances make calibration impossible. Measurements and setpoints on the laser current
source are not guaranteed to meet accuracy specifications after this command is issued. Accuracy
will remain unspecified until calibration is performed on the module.
Laser:CAL:Default-action: sets all of its laser calibration constants to their default values.
The LASER:CAL:LDI command is used to initiate the calibration procedure for the laser current
setpoint, measurement, and current limit.
None.
Both low and high bandwidth modes, along with current limit, are calibrated during this procedure.
See the Service Reference portion of this manual for complete calibration instructions.
Laser:CAL:LdI-action: enters calibration mode for laser current.
The LASER:CAL:LDV command is used to initiate the calibration procedure for the laser voltage
measurement.
None.
See the Service Reference portion of this manual for complete calibration instructions.
Laser:CAL:Ldv-action: enters calibration mode for laser voltage measurement.
The LASER:CAL:MDI command is used to initiate the calibration procedure for the laser photodiode
current setpoint and measurement system.
None.
See the Service Reference portion of this manual for complete calibration instructions.
Laser:CAL:MDI-action: enters the laser photodiode current calibration mode.
The LASER:CAL:MEAS command is used to enter measured values during the laser calibration
procedure.
An <nrf value> which represents the measured value expected for the present Laser calibration
state.
See the Service Reference portion of this manual for complete calibration instructions.
Laser:CAL:MEAS 4.95-action: the module uses the value 4.95 for the required measurement value.
