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 50Ωsource 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. 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.
