CHAPTER 4
The LASer:EVEnt? query returns the value of the status event register of the LASER operations.
−where the response is the sum of the following:
Notes The LASER conditions that are reported in the status byte can be set by using the
LASer:ENABle:EVEnt command.
The LASER event status is only cleared when the event status is read or by the *CLS command,
while the condition status is constantly changing.
Examples "LAS:EVE?" −response: 513, means that the LASER output tolerance changed and current limit
events have occurred since the last LASer:EVEnt? query.
"Radix Hex; Laser:Event?" −response: #H88, means that the LASER Power limit and Open circuit
events have occurred since the last LASer:EVEnt? query.
The LASer:INC command increments the selected laser control mode set point by one or more
steps. Optional parameters allow multiple steps to be incremented and the time (in milliseconds)
between increments 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−3714B default values are 0.001/0.002 mA (50/100 mA range), 0.01 mW, or 1 µA (if
