Information
The
AM 502 is a DC-coupled differential
Amplifier with
excellent common-mode rejection capabilities and high gain
for low-voltage measurements. The DC OFFSET capability
permits nulling up to one volt DC, so that low level, low
frequency signals impressed on a DC level can be amplified
without the degradation often introduced by AC input coupling.
High and low frequency —3 dB points can be selected at the
front panel to suit the application. Signal inputs and
outputs are available at the rear connector as well as at
the front panel. A front-panel lamp indicates most
over-range conditions of excessive input signal (either
differential or common mode), excessive gain, or excessive
offset.
