Parameters

An <nrf value>; 1=on, 0=off.

Notes

There is a two-second delay after the output is turned on before the output shorting relay

 

is opened. Following this, the output current ramps up to the current setpoint slowly to

 

protect the laser. Therefore, the time to turn the output on and reach the setpoint current

 

varies from two to about three seconds.

 

After the output is turned on, it may be useful to wait until the output is stable (within

 

tolerance) before performing further operations, but it is not necessary. When the LASER

 

output is off, it is safe to connect or disconnect devices to the LASER output terminals.

 

When the LASER output is off, an internal short is placed across the output terminals.

Examples

"LAS:I 20; LAS:OUT ON" -action: sets the laser output current to 20 mA and then turns

 

the output on.

- where the response is 0 or 1

 

 

 

Notes

Although the status of the switch is on, the output may not have reached the setpoint

 

value.

 

 

 

 

Examples

"Las:OUT?"

-response: 0, means that the output switch is disabled, devices may be

 

safely disconnected or connected at the LASER output terminals.

"LAS:OUT?" -response: 1, means that the LASER output switch is enabled, LASER output is present.
