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 50Ω source
impedance. A 600Ω output is also provided.
The unit can provide up to 15 volts peak to peak into a 50Ω
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.
