ABSTRACT:
The electrical signal observing device measures the electrical signal by applying the electrical signal to be measured to an optical amplifier in order to modulate a short pulse light train directed through the electrical amplifier. The electrical signal to be measured acts as a gain control for the optical amplifier. The photodetector detects the output of the optical amplifier and applies a resultant electrical signal to an integrator circuit after which the signal is displayed. The signal may be displayed in a time base fashion using a sweep generated by a delay system of the short pulse light train.
