LDX-32420 Device-Dependent Command Reference
The LASer:DEC command decrements the selected laser control mode setpoint by one
or more steps. Optional parameters allow multiple steps to be decremented and the time
(in milliseconds) between decrements to be set, respectively. This is an overlapped
command. Other commands may be executed while this function is in progress.
Steps: optional parameter indicating number of steps
Delay: optional parameter specifying the number of milliseconds between steps.
The default step amount is one step. 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 CALMD = 0).
If the step parameter is specified, but not the delay parameter, the user may decrement
the LASER setpoint by a multiple of the LAS:STEP size, without changing the LAS:STEP
size.
If both parameters are used, the user may create an automated stepping ramp function
for the LASER output.
If the first parameter is entered as zero, "LAS:DEC 0", the command will do nothing.
The minimum time to complete one decrement is about 20 ms. Therefore, values for the
second optional parameter (time between decrements) have a practical minimum of 20.
"LAS:MODE:I; LAS:STEP 3; LAS:DEC" - action: The laser source current setpoint is
decremented by 0.003 A.
"LAS:MODE:I; LAS:STEP 3; LAS:DEC 3" - action: The laser source current setpoint is
decremented by three times the amount described in the first example.
"LAS:MODE:I; LAS:STEP 3; LAS:DEC 3,5000" - action: The laser source current
setpoint is decremented by the amount described in the first example, three times, with
five seconds between decremental steps.
The LASer:DISplay command enables or disables (turns off) the display and some LEDs
The LASer:DISplay? query returns the value shown on the display.
Turning the display and LEDs off means that a message of all blank spaces is sent to the
display, and most of the LEDs will be turned off.
LASer:DISplay? returns the actual (6-character) string from the output buffer to the
display. If the display is disabled, it returns "
"las:dis 1" - action: turns the LASER display on and enables the LASER indicator LEDs.
"LAS:DIS?" - response: "- 99.9", means the LASER display shows "- 99.9".
