LDX-3232 Device-Dependent Command Reference
42 LDX-3232
CHAPTER 4
The LASer:CALMD? query returns the value of the laser's photodiode feedback
responsivity (CAL PD parameter) setting.
Syntax Diagram
Notes If this value is 0, the LDX-3232 will be set to operate in constant I
PD
mode, and the I
PD
setpoint value will be in effect. If this value is non-zero, the LDX-3232 will be set to
operate in constant P
PD
mode, and the P
PD
setpoint value will be in effect.
If this value is 0, the front panel P
PD
will display "-.-” and no P
PD
value can be calculated.
Examples "LASER:CALMD?" -response: 0, means the LDX-3232 is set for operation in constant
I
PD
mode (if P mode is also selected).
"Las:Calmd?" -response: 1.1, means the LDX-3232 is set for operation in constant P
PD
mode (if P mode is also selected) and the responsivity is set to 1.1 µA/mW. 1.1 µA of
photodiode feedback current represents 1 mW of optical power.
The LAS:CAL:CONST? query returns a stored calibration value. It is intended for factory
use only.
