F20A

GENERAL DESCRIPTION

The F20A is a general purpose linear amplifier designed for laboratory use. It is based on a fast high-voltage operational amplifier with a feedback network chosen to give a voltage amplification of 20 times. Any function or arbitrary waveform generator with output voltage up to ±10 V can be used as an input device. This device outputs high voltage signals at high frequency. It is, thus, imperative for the safe operation that the user understands the possibilities and limitations of the instrument.

INPUT AMPLITUDE

The amplitude of the input signal should normally be kept within ±7.5 V. The input protection network limits the signal amplitude delivered to the power amplifier to a safe value. It also effectively cuts accidental spikes and overshoots. However, large and/or prolonged overvoltage at the input may blow the microfuse in the input protection circuit. (A spare fuse is provided inside the instrument. If possible, contact service@pendulum-instruments.com for advice before opening the instrument case.)
