The LASER:INC command increments the laser constant-current set point by one or more steps. A
second parameter allows the time (in milliseconds) between increments to be set.
Two values are required. The first represents the number of steps, and the second is the time in
milliseconds between steps.
The step size can be set using the LASER: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 increment is about 10 to 20 msec. Therefore, values for the
second parameter (time between increments) have a practical minimum of 20. The maximum
number of msec is 65535.
LASER:STEP 0.5; LASER:INC 10,50-action: the step size is set to 0.5 mA, and the set point is
incremented by 0.5 mA ten times, each increment being separated by 50 msec.
The LASER:LDV? query returns the value of the measured laser voltage.
None. The response is an <nrf value>.
Response is the measured Laser output voltage in Volts, regardless of control mode.
This measurement is updated approximately once every 600 msec.
LASER:ldv?-response: 3.03, means the measured Laser output voltage is 3.03 volts.
Laser:LDV?-response: 1.0, means the measured Laser output voltage is 1.00 volts.
LASER:LIMit:I
•
LASER:LIMit:I?
•
The LASER:LIMit:I command sets the laser current limit value.
An <nrf value> which represents the laser limit current, in mA.
The current limit is in effect in all modes of operation.
LASER:LIM:I 80-action: the laser current limit is set to 80 mA.
:Laser:Limit:I 160-action: the laser current limit is set to 160 mA.
