Syntax:
":PDBIA?"
Response:
[:PDBIA OFF]
[:PDBIA ON]
Description: Queries the state of the photo diode bias voltage.
Before switching on the bias voltage make sure that the monitor
If the monitor diode is forward biased with a voltage the resulting
current may damage or even destroy the monitor diode (= the laser
