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 50Ωsourceimpedance. 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.
An example of this is a buffer amplifier to a waveform DAC such
as the VIPS20 from the TTi virtual instrument module range. The
WA301 can provide a waveform amplitude variable between
300mV and 30V pk-pk from 50Ω whilst maintaining full 12-bit
resolution. Lower output levels could be generated by sacrificing
resolution.
