详情介绍
详细信息
The Model 250S1G4 is a portable, self-contained, air-cooled, broadband, completely solid-state amplifier designed for applications wher instantaneous bandwidth, high gain and linearity are required. Push-pull circuitry is utilized in all high power stages in the interest of lowering distortion and improving stability. The Model 250S1G4, when used with a sweep generator, will provide a minimum of 250 watts of RF power.
The Model 250S1G4 is equipped with a Digital Control Panel (DCP) which provides both local and remote control of the amplifier. The DCP uses a graphic liquid crystal 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 and RF output level protection. All amplifier control functions and status indications are available remotely in GPIB/IEEE-488 format, RS-232 hardwire and fiber optic, USB, and Ethernet. The bus interface connector is located on the back panel and positive control of local or remote operation is assured by a Local/Remote switch on the front panel of the amplifier.
The low level of spurious signals and linearity of the Model 250S1G4 make it ideal for use as a driver amplifier in testing wireless and communication components and subsystems. It can be used as a test instrument covering multiple frequency bands and is suitable for a variety of communication technologies such as CDMA, W-CDMA, TDMA, GSM etc. It is also suitable for EMC Test applications wher undistorted modulation envelopes are desired.
The 250S1G4 has the ability to be upgraded at a later date to the Model 350S1G4, 350 watt amplifier. Upgrading to the Model 350S1G4 allows for future upgrades by utilizing our Expandable Power Technology.
