The modulation output gives a TTL level signal of the same frequency as the
internal modulating signal.
The modulation input allows you to input a signal to modulate the power of the
optical output.
The analog output gives a dc-signal proportional to the output power. The
relationship between this voltage level and the output power is not calibrated,
but is approximately 1mV for each 1
W.
At the back of the 8168F, you also have a Remote Interlock Connector. This
is to protect the user from injury. If the short-circuit at this BNC connector is
opened, the laser is switched o immediately and cannot be switched on until it
is closed again.
Starting the 8168F
When you turn on the 8168F, the instrument is locked. This is to prevent
unauthorized persons from using this Laser Safety Class IIIb instrument. The
Starting screen for the 8168F is shown below:
