Command Reference
Enters the slope and offset calibration constants for forward voltage measurement.
Two <nrf values>. The first parameter is the slope and the second is the offset of the
measurement.
This command allows for calibration and linearization of the laser voltage measurement
at the output connector. The complete calibration procedure is outlined in Chapter 6.
Default values for slope and offset are 1 and 0, respectively.
"las:cal:ldv 2.953417, -0.354155" -action: Adjusts the internal A/D calibration to linearize
the measurement by entering a new slope and offset of 2.953417 and -0.354155,
respectively.
"Las:Cal:LDV 1.0, 0.0" -action: Resets the laser voltage measurement calibration
constants to default values.
Returns the current laser voltage measurement calibration constants stored within the
instrument.
None.
Two values are returned by this query, a slope and offset value, respectively. This
command is used to verify successful calibration by reading back the stored constants.
This procedure is outlined in Chapter 6.
"las:cal:ldv?" -response: 1.545116, 0.379247, meaning a slope of 1.545116 and an
offset of 0.379247 had been previously entered as part of the calibration process.
Enters the slope and offset calibration constants for laser current limit setpoint.
Two <nrf values>. The first parameter is the setpoint slope and the second is the
setpoint offset.
This command allows for calibration and linearization of the laser current limit versus
setpoint. The complete calibration procedure is outlined in Chapter 6.
Default values for slope and offset are 1 and 0, respectively.
"las:cal:limiti 1.0046, -0.00426" -action: Adjusts the internal calibration to linearize the
current limit setpoint by entering a new slope and offset of 1.0046 and -0.00426,
respectively.
"Las:Cal:LIMITI 1.0, 0.0" -action: Resets the laser current limit setpoint calibration
constants to default values.
