The LASer:CALPD? query returns the value of the laser's photodiode feedback responsivity (CAL PD
parameter) setting for the selected channel.
SYNTAX DIAGRAM
PARAMETERS None. The response is an <nrf value>.
POINTS OF
INTEREST If this value is 0, the selected channel's monitor current/power conversion will not be done. If
the mode is set to MDP, the actual set point will be forced to be (near) 0, regardless of the
LAS:MDP value.
If this value is 0, the front panel P will display "-----", and no P value can be calculated.
EXAMPLES "Laser:CALPD?" -response: 0, means the selected channel's monitor current/power conversion
will not be done. If the mode is set to P, the actual set point will be forced to be (near) 0,
regardless of the LAS:MDP value.
"Las:CALPD?" -response: 1.1, means the selected channel is set for operation in constant P
mode (if MDP mode is also selected) and the responsivity is set to 1.10 µA/mW. 1.1 µA of
photodiode feedback current represents 1 mW of optical power.
