Information:
                                    The Model 200W1000A is a portable, self-contained,
air-cooled, broadband, solid state amplifier
designed for applications where instantaneous bandwidth and
high gain are required. Push-pull
circuitry is utilized in the high power stages to lower
distortion and improve stability. The
200W1000A, when used with an RF sweep generator, will
provide a minimum of 200 watts of swept
power. Included is a front panel gain control which permits
the operator to conveniently set the
desired output level. The 200W1000A is protected from RF
input overdrive by limiting diodes and
an RF input leveling circuit which controls the RF input
level to the RF amplifier first stage when
the RF input level is increased above 0 dBm. The RF
Amplifier stages are protected from over
temperature by removing the DC voltage to them if an over
temperature condition occurs due to
cooling blockage or fan failure. There is a digital display
on the front panel to indicate the operate
status and fault conditions when an over temperature, power
supply, or amplifier fault has occurred.
The unit can be returned to operate when the condition has
been cleared. The 200W1000A includes
digital control for both local and remote control of the
amplifier. This 8-bit RISC microprocessor
controlled board provides both IEEE-488 (GPIB) and
asynchronous, full duplex RS-232 control of
all amplifier functions.
