Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
The LASER:ENABle:OUTOFF command sets the Laser Output Off Enable register. The bits in this
register specify the conditions that will cause the Laser current source to automatically turn off.
An <nrf value> whose sum represents the enabled bits:
1 - Current limit
2 - Voltage limit
4 - n/a
8 - Power limit
16 - n/a
32 - n/a
64 - n/a
128 - n/a
This register is read using the LASER:ENABle:OUTOFF? query.
The factory default value for this register is 8: only Power Limit will shut off the output.
Enabling voltage limit will cause the output to shut off when the laser diode voltage reaches a level
that is about 0.25 volts below the VLim setpoint. Regardless of how this register is set, the current
source will shut off when the laser diode voltage exceeds the VLim setpoint: this is an Open Circuit
error.
LASER:ENAB:OUTOFF 9-action: sets the LASER Output-Off enable register so that either a Power
Limit or a Current Limit condition will cause the LASER output to be turned off.
Open Circuit or Interlock Open conditions will always turn off the current source. They are not
included in the Output Off Enable Register because they cannot be disabled.
The LASER:ENABle:OUTOFF? query returns the contents of the Laser Output Off Enable register.
None. The response is the sum of the following:
1 - Current limit
2 - Voltage limit
4 - n/a
8 - Power limit
16 - n/a
32 - n/a
64 - n/a
128 - n/a
This register can be set by using the LASER:ENABle:OUTOFF command. The laser output status
can be monitored by the LASER:EVEnt? query.
LASER:ENAB:OUTOFF?-response: 8, means that the Power Limit condition will cause the laser
output to be turned off.
