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.
Syntax Diagram
Parameters 0, 1, or 2. The first optional parameter is the number of steps, and the second optional
parameter is the number of ms between steps.
Notes The decremental default amount is one step. The step size can be edited via the
LAS:STEP command. LDX-3232 default values are 0.1 mA, 0.1 mW, or 1 µA.
If the first optional parameter is used, but not the second, the LASER setpoint is
incremented by a multiple of the LAS:STEP size without changing the LAS:STEP size.
The second optional parameter is the time, in ms, between steps.
If both optional parameters are used, the user may create an automated stepping ramp
function for the LASER output.
If the first optional parameter 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.
Examples “LAS:MODE:I; LAS:STEP 3; LAS:INC” -action: The laser source current setpoint is
incremented by 0.03 mA.
“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
fiveseconds between incremental steps.
“LAS:STEP 1; LAS:Mode:P; Las:INC” -action: The power setpoint is incremented by
0.01 mW.
