03_10
Requests the instrument to identify itself.
None.
Returns a comma delimited standard format ASCII identification string, from information
stored in the instrument during manufacture. The information will contain at a minimum
the instrument's model number and serial number.
"*IDN?" -response: ILX Lightwave,3650,36501234YN,1.2
Enters the slope and offset calibration constants for laser current 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 output current versus
setpoint. The complete calibration procedure is outlined in Chapter 6.
Default values for slope and offset are 1 and 0, respectively.
"las:cal:ldi 1.0046, -0.00426" -action: Adjusts the internal D/A calibration to linearize the
output by entering a new slope and offset of 1.0046 and -0.00426, respectively.
"Las:Cal:LDI 1.0, 0.0" -action: Resets the laser current setpoint calibration constants to
default values.
Returns the current laser current setpoint 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:ldi?" -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.
