The LASer:DEC command decrements the selected laser control mode set point by one
or more steps. Optional parameters allow multiple steps to be decremented and the time
(in milliseconds) between decrements to be set, respectively.
Parameters 0, 1, or 2. The first optional parameter is the number of steps, and the second optional
parameter is the number of milliseconds between steps.
Notes The decremental default amount is one step. The step size can be edited via the
LAS:STEP command. LDC-3714C default values are 0.001/0.002 mA (50/100 mA
range), 0.01 mW, or 1

A (if CALMD = 0), depending on the mode of operation.
LDC-3724C default values are 0.01 mA, 0.01 mW, or 1

A. LDC-3744C default values
are 0.1 mA, 0.1 mW, or 1

A.
If the first optional parameter is used, but not the second, the user may decrement the
LASER set point by a multiple of the LAS:STEP size, without changing the LAS:STEP
size.
If the 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:DEC 0", the command will do
nothing.
The minimum time to complete one decrement is about 20 msec. Therefore, values for
the second optional parameter (time between decrements) have a practical minimum of
20.
Examples "LAS:MODE:I; LAS:STEP 3; LAS:DEC" -action: The laser source current set point is
decremented by 0.3 mA (LDC-3744C), or 0.03 mA (LDC-3724C), or 0.003 mA
(LDC-3714C on 50 mA range), or 0.006 mA (LDC-3714C on 100 mA range).
"LAS:MODE:I; LAS:STEP 3; LAS:DEC 3" -action: The laser source current set point 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 set
point is decremented by the amount described in the first example, three times, with 5
seconds between decremental steps.
The LASer:DISplay command enables or disables (turns off) the LASER display and
LASER section's indicator LEDs.SYNTAX DIAGRAM
Parameters An <nrf value>;-where 1 = on, 0 = off.
Notes Turning the LASER display and LEDs off means that a message of all blank spaces is
sent to the LASER display, and all of the LASER section's indicator LEDs will be turned
off.
Examples "las:dis 1" -action: turns the LASER display on and enables the LASER indicator LEDs.
"Laser:dis Off" -action: turns the LASER display and disables the LASER indicator
LEDs.
