LDX-32420 Device-Dependent Command Reference
The LASer:INC command increments the selected laser control mode setpoint by one or
more steps. Optional parameters allow multiple steps to be incremented and the time (in
ms) between increments to be set, respectively. This is an overlapped command. Other
commands may be executed while this function is in progress.
Steps: optional parameter indicating how many times to step
Delay: optional parameter specifying the number of milliseconds between steps.
The default step amount is one. The step size can be edited via the LAS:STEP
command. LDX-32420 default values are 0.001 A, 0.01 W, or 1 µA.
If the step parameter is specified, but not the delay, the LASER setpoint is incremented
by a multiple of the LAS:STEP size without changing the LAS:STEP size. The delay is
the time, in ms, between steps.
If both parameters are used, the user may create an automated stepping ramp function
for the LASER output.
If the steps is entered as zero, "LAS:INC 0", the command will do nothing.
The minimum time to complete one increment is about 20 ms. Therefore, values for the
second optional parameter (time between increments) have a practical minimum of 20.
This command should not be overlapped with "LAS:DEC" or other "LAS:INC" commands.
"LAS:MODE:I; LAS:STEP 3; LAS:INC" -action: The laser source current setpoint is
incremented by 0.003 A.
"LAS:MODE:I; LAS:STEP 3; LAS:INC 3" -action: The laser source current setpoint is
incremented by three times the amount described in the first example.
"LAS:MODE:I; LAS:STEP 3; LAS:INC 3,5000" - action: The laser source current setpoint
is incremented by the amount described in the first example, three times, with five
seconds between incremental steps.
"LAS:STEP 1; LAS:Mode:P; Las:INC" - action: The power setpoint is incremented by
0.01 W.
The LASer:LDI command sets the laser control current setpoint.
The LASer:LDI? query returns the value of the measured laser current.
- where the response is the most recent laser current measurement.
Amps: represents the (laser) output current setpoint in A.
Setpoint is the same for both low and high bandwidth output modes.
Response is the measured laser output current for either low or high bandwidth modes.
This measurement is updated approximately once every 600 ms.
"Las:LDI 4" - action: sets the laser output current setpoint to 4.00 A.
"LAS:ldi?" - response: 15.0, means the measured laser output current is 15.0 A.
