Series AR amplifiers are rack-mountable units which incorporate
the Series AM amplifier in a cabinet containing a built-in
universal AC power supply (for models up to 100 watts).
Models are available for operation at frequencies from 1 MHz
to 2 GHz and output power from 10 to 250 W. They are
forced-air cooled by blowers built into the mechanical package.
AR models are also available with an optional IEEE BUS for
remote control and monitoring (ARD version).
