The LASer:SET:MDI? query returns the laser monitor PD current set point value (when
CALPD = 0), in

A.
Notes The monitor photodiode current is directly proportional to the laser optical output power.
Therefore, the I
PD
set point may be used to control optical output of the laser.
Examples "las:set:mdi?" -response: 30.0, means the laser monitor PD current is set point is 30

A,
for use in constant P mode with CALPD = 0.
"LAS:Set:MDI?" -response: 100.0 means the laser monitor PD current is set point is 100

A, for use in constant P mode with CALMD = 0.
The LASer:SET:MDP? query returns the laser monitor PD power set point value (when
CALMD [CAL PD] is not zero), in mW.
Notes This set point is used in constant MDP mode only.
Examples "LAS:Set:MDP?" -response: 10.0, means the laser monitor PD feedback set point is
10.0 mW (CALPD > 0).
"Laser:Set:MDP?" -response: 25.0, means the laser monitor PD feedback set point is
25.0 mW (CALPD > 0).
The LASer:STEP command is used to increment or decrement the selected laser control
mode set point by the given amount, when used with the LASer:INC or LASer:DEC
command.
Parameters An integer value of the step amount, in the range 1 to 9999.
Notes The step of 1 corresponds to the smallest display resolution for the mode. For example, a
step of 1 means 0.1 mA (3744C) or 0.01 mA (3724C) or 0.002 mA (3714C, 100 mA
range) or 0.001 mA (3714C, 50 mA range), 0.01 mW, or 1

A (if CALPD = 0).
Examples "Las:Mode:i; Las:ldi 20; Las:Step 100; Las:Inc; Las:set:ldi?" -action: sets the step to 1.0
mA (3724C), so the Las:set:ldi? query will return a value of 21.0 mA.
"LAS:STEP 1000" -action: sets the step size to 1000; could mean 10.0 mA (3724C),
10.0 mW, or 100

A.
