Model 30W1000B
M1 through M5
30 Watts CW
1MHz–1000MHz
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.
