EXAMPLES
"LAS:COND?" -response: 1027, means that the output is on, and the current limit and voltage
limit conditions currently exist.

The LASer:DEC command decrements the selected channel's laser constant-current set point by one or more
steps. Parameters allow multiple steps to be decremented and the time (in milliseconds) between decrements
to be set, respectively.

LAS
PARAMETERS
Two <nrf values> are required. The first one represents the number of steps, and the second is
the number of milliseconds between steps.
POINTS OF
INTEREST
The step size can be edited via the LAS:STEP command. Its default value is 1.0 mA.
The first parameter (number of steps) must be an integer between 1 and 50000.
The minimum time to complete one decrement is about 10 to 20 msec. Therefore, values for the
second parameter (time between decrements) have a practical minimum of 20. The maximum
number of msec is 65535.
Only the LAS:LDI set point is decremented via this command regardless of LAS:MODE setting
or LAS:OUTPUT status.
EXAMPLES
"LAS:STEP 0.3; LAS:DEC 1,10" -action: The laser source current set point is decremented by
0.3 mA.
"LAS:STEP 0.3; LAS:DEC 3,10" -action: The laser source current set point is decremented by
0.9 mA (0.3 mA * 3).
"LAS:STEP 0.3; LAS:DEC 3, 5000" -action: The laser source current set point is decremented
by 0.3 mA, three times, with 5 seconds between decremental steps. So the Laser output is
decremented a total of 0.9 mA after 10 seconds.
