touch screen display to indicate the operate
status and fault conditions if an over-
temperature or power supply fault has oc-
curred. The unit can be returned to operate
when the condition has been cleared.
All amplifier control functions and status indi-
cations are available remotely through the
included Remotes Package. The Remotes Pack-
age includes GPIB/IEEE-488 format, RS-232
hardwire and fiber optic, USB, and Ethernet.
The bus interface connector is located on the
back panel and positive control of local or
remote operation is assured by a Local/Remote
keyswitch on the front panel of the amplifier.
Also included with the Remotes Package is a
safety interlock circuit for use with external
safety switch interlocks. This circuit prevents the
amplifier from going into operate mode unless
the external connection is made. A jumper
plug is provided for cases where this function-
ality is not needed.
The export classification for this equipment is
EAR99.
The Model 5000A225A is a solid-state, self-
contained, broadband amplifier designed for
applications where instantaneous bandwidth,
high gain and linearity are required. The am-
plifier is air-cooled using internal self-
contained liquid cooling for high performance
and reliability. A stylish, contemporary enclo-
sure allows for easy portability.
The Model 5000A225A, when used with a
sweep generator, will provide a minimum of
5000 watts of RF power. Included is a front
panel gain control which permits the operator
to conveniently set the desired output level. The
5000A225A is protected from RF input over-
drive by an RF input leveling circuit which con-
trols the RF input level to the RF amplifier first
stage when the RF input level is increased
above 0dBm. The RF amplifier stages are pro-
tected from over-temperature by removing the
DC voltage to them if an over-temperature
condition occurs due to cooling blockage or
fan failure. The Model 5000A225A is
equipped with a Digital Control Panel (DCP)
which provides both local and remote control
of the amplifier. The DCP uses a color LCD
