GENERAL DESCRIPTION

The WA301 is a DC to 1MHz amplifier with a maximum output (e.m.f.) of 30 volts peak to peak from a 50W source impedance. A 600W output is also provided.

The unit can provide up to 15 volts peak to peak into a 50W load and can drive up to 300mA peak into a low impedance or short circuit.

Fully variable gain between x1 and x10 is provided by a rotary vernier with calibrated end stops. A -20dB output attenuator is also incorporated.

An "output clip" LED is provided to warn if the output amplitude exceeds ?15V. APPLICATIONS

Most function generators have a maximum open-

circuit output voltage of 20V peak to peak. The WA301 enables this to be boosted to 30V peak to peak.

Commonly the WA301 will be used as a slave to a function generator with the gain set to x10. Thus an output of 3V pk-pk at the function generator would give rise to an output of 30V pk-pk from the WA301.

Alternatively the variable gain facility might be used to provide an adjustable output level from a fixed level source.
