Abstract
Apparatus for receiving an optical test signal, from a transmitter pulsating at a selected repetition rate, comprising, a portable voltage source, a PIN diode for sampling the test signal and generating a voltage pulsating at said repetition rate and with an amplitude proportionate to the amplitude of the sampled test signal, an indicator for indicating the amplitude of the sampled test signal, amplifying means connected between the indicator and the PIN diode, a filter circuit between the PIN diode and the amplifying means for reacting to the transitions in amplitude of said voltage from the PIN diode.
