The LASer:SET:MDI? query returns the selected channel's laser monitor photodiode current set point value, in
µA.
SYNTAX DIAGRAM
PARAMETERS None. The response is an <nrf value> which represents the selected channel's constant IPD set
point value, in µA.
POINTS OF
INTEREST The monitor photodiode current is directly proportional to the laser optical output power.
Therefore, the IPD setpoint may be used to control optical output of the laser.
EXAMPLES "las:set:mdi?" -response: 30.0, means the selected channel's laser monitor PD current setpoint
is 30 µA, for use in constant MDI mode.

The LASer:SET:MDP? query returns the selected channel's laser optical power set point value, in mW.
SYNTAX DIAGRAM
PARAMETERS None. The response is an <nrf value> which represents the selected channel's constant P set
point, in mW.
POINTS OF
INTEREST This set point is used in constant MDP (P) mode only.
EXAMPLES "LAS:Set:MDP?" -response: 10.0, means the selected channel's laser monitor PD feedback set
point is 10.0 mW (CALPD > 0).
