The LASER:DEC command decrements the 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.
Two values (see Parameters on page 25 for information about <nrf values>) are required. The first
one represents the number of steps to decrement, and the second is the number of milliseconds
between steps.
The step size is set with the LASER:STEP command; its default value is 1.0 mA.
The first parameter, the number of steps to decrement, 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 LASER:LDI set point is decremented using this command, regardless of mode setting or
output status (on or off).
LASER:STEP 0.3; LASER:DEC 1,100-action: the Laser constant-current setpoint is decremented
by 0.3 mA.
LASER:STEP 0.5; LASER:DEC 4,100-action: the step size is set to 0.5 mA, the setpoint is
decremented by 4 steps of 0.5 mA, separated in time by 100 msec, for a total decrement of 2.0 mA.
laser:step 1.0; laser:dec 10,1000-action: the step size is set to 1.0 mA, the setpoint is decremented
by 1.0 mA, 10 times, with 1 second between decrement steps. The Laser output is decremented a
total of 10 mA over a period of 10 seconds.
The LASER:ENABle: command path is used to access the laser status enable commands and
queries.
