The LASer:RANge command selects the laser's drive current output range.
Parameters
An <nrf value> that represents the laser current output range.
2 = 2000 mA, and 4= 4000 mA range
Notes
This range setting effects the Laser Drive Current output current range only. The Laser
Drive Current output should be “off” when this command is issued. If the Laser Diode
Current output is “on” when this command is issued, the LDX-3232 will generate error
E515, and the range will not be changed.
Examples
"LAS:RAN 4" -action: sets the laser output drive current range to 4000 mA.
"Laser:range 2" -action: sets the laser output drive current range to 2000 mA.
The LASer:RANge? query returns the value of the Laser Drive Current range.
- where the response is in integer; 2 means 2000 mA range and 4 means 4000 mA
range.
Notes
The resolution and accuracy of the laser limit current are dependent on the Laser Drive
Current output range.
Examples
"LAS:RAN?" -response: 2, means that the Laser Drive Current range is 2000mA.
"LAS:range?" -response: 4, means that the Laser Drive Current range is 4000mA.
