The Model 30W1000B 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
30W1000B, when used with an RF sweep generator, will provide a minimum of 30 watts of swept
power. Included is a front panel gain control which permits the operator to conveniently set the
desired output level. The 30W1000B 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 30W1000B 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.
