The Model 800A3B is a self-contained, air-cooled, broadband, solid-state amplifier designed for applications where instantaneous bandwidth and high gain are required. The Model 800A3B, when used with an RF sweep generator, will provide a minimum of 800 W of swept power.
The Model 800A3B is equipped with a digital control panel which provides both local and remote control of the amplifier. The DCP uses a color LCD touch screen and a single rotary knob to offer status reporting and control 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, RF output level protection, and a transformer with selectable taps for matching to different load impedances.
All amplifier control functions and status indications are available remotely in GPIB/IEEE-488, RS-232, RS-232 Fiber Optic, Ethernet and USB. The buss interface connectors are 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 800A3B amplifier is intended for applications where the load impedance is not necessarily 50 ohms. The selectable output impedance provides the capability to drive loads that would otherwise cause a high SWR and limit the delivered power. The impedance matching transformer uses high-voltage/high-current vacuum relays so the user can “hot switch” between impedances without damage.
The Model 800A3B is housed in a cabinet and designed to provide complete standalone performance for RF testing. The export classification for this equipment is EAR99.
