Model 1000W1000D, M1, M2
1000 Watts CW
80MHz–1000MHz
The Model 1000W1000D is a self-contained, air-cooled, broadband, completely solid-state amplifier designed for
applications where instantaneous bandwidth and high gain are required. Push-pull circuitry is utilized in all high power
stages in the interest of lowering distortion and improving stability. The Model 1000W1000D, when used with an RF
sweep generator, will provide a minimum of 1000 watts of swept power.
The Model 1000W1000D is equipped with a Digital Control Panel (DCP) which provides both local and remote control of
the amplifier. The DCP uses a digital display, menu assigned softkeys, a single rotary knob, and four dedicated switches
(POWER, STANDBY, OPERATE and FAULT/RESET) to offer extensive control and status reporting capability. The display
provides operational presentation of Forward Power and Reflected Power plus control status and reports of internal
amplifier status. Special features include a gain control, internal/external automatic level control (ALC) with front panel
control of the ALC threshold, pulse input capability and RF output level protection. Also included is an internal RF detector
that provides an output for use in self-testing or operational modes.
All amplifier control functions and status indications are available remotely in GPIB/IEEE-488 format and RS-232
hardware, and fiber optic. The buss interface connector is located on the back panel and positive control of local or
remote operation is assured by a keylock on the front panel of the amplifier.
The 1000W1000D is housed in a single equipment rack and is designed to provide complete stand-alone performance
for RF testing. It is also configured to be used as a sub-amplifier in a 2000-watt, 3000-watt or 4000-watt higher power
amplifier. It can be added to in an incremental fashion to become a part of these higher power units yet still be used as a
stand-alone 1000 watt amplifier.
