A400D

GENERAL DESCRIPTION

The A400D 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 low output impedance and output voltage up to ±10 V can be used as an input device. The instrument contains two identical amplifier that share a single power supply and a common ground reference. The amplifier 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. Isolated BNC output connector is used to comply with safety requirements.

INPUT AMPLITUDE

The amplitude of the input signal should normally be kept within ±10 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.)
