Broadband Test Amplifier
The model 150W1000 broadband test amplifier offers 150 W minimum power and frequency response from 80 to 1000 MHz. The unit provides the extra margin of power needed when testing to International Electrotechnical Commission 10 V/m requirements at 3 m from 80 to 90 MHz. The amplifier is also suitable for use in automotive bulk current injection applications. The unit is equipped with a digital control panel that provides local and remote control. A four-line digital display, menu-assigned softkeys, rotary knob and four dedicated switches offer extensive control and status reporting capability. Operational presentation of forward and reflected power, control status and reports of internal amplifier status are also provided. Special features include gain control, internal/external automatic level control (ALC) with front-panel or remote control of the ALC threshold, pulse input capability and RF output level protection. The amplifier limits reflected power to 100 W. All amplifier control functions and status indications are available remotely in GPIB/IEEE-488 and RS-232 formats. Price: $27,000.
