The analog output is the BNC connector on the back of the

optical head. It outputs a voltage directly proportional to the

strength of the optical signal at the optical input in the current

range. The analog signal is always in the range between 0 and

2V, 2V corresponding to a full power input signal in the current

range, 0V corresponding to no input signal.

During autoranging, the level to which 2V corresponds changes.

You should disable autoranging when using the analog output.

Applications

Possible applications for the analog output are:

• to close the feedback loop controlling the current supplied to

a laser

• to aid positioning the system for fiber alig纳米ent tasks

• to monitor optical power on an oscilloscope

The analog signal reacts instantaneously to the input signal,

whereas the power shown on the display is subject to averaging.
