MODEL 1000L 1200 WATTS CW 2500 WATTS PULSE 10kHz-220 MHz 160 School House Road, Souderton, PA 18964-9990 USA Phone 215-723-8181*FAX 215-723-5688 The Model 1000L is an economical, self-contained, air-cooled broadband amplifier designed for laboratory applications that require instantaneous bandwidth, high gain and high power output. Housed in a stylish contemporary enclosure, the Model 1000L is smaller than competitive units with similar power levels. All operating controls are functionally grouped on the front panel for simplicity of operation. These include modern, lighted push-button switches for the command functions, POWER, STANDBY, OPERATE and PULSE, a control for setting the output level of the amplifier, and a meter for monitoring critical operating voltages and currents. Remote control is provided through a rear panel mounted connector. Isolated TTL level remote control can be accomplished using our CP2001 interface. Isolated IEEE-488 compatible control can be provided with our CP3000. A highly versatile unit, the Model 1000L features rugged circuitry and a quick-acting, solid state crowbar circuit to protect the final amplifier tubes from damage due to internal arcing. An electronic circuit is provided to enable rapid gating or blanking of the amplifier. 1000L TYPICAL POWER OUTPUT 3500 3000 PULSE 2500 WATTS CW 2000 LINEAR @ 1dB COMPRESSION 1500 1000 500 0 0.001 0.01 0.1 1 10 100 1000 FREQUENCY (MHz) REV060396 SPECIFICATIONS Model 1000L POWER OUTPUT High Range Pulse Minimum .................................................................. 2500 watts to 150MHz 1750 watts to 220MHz Duty Cycle ................................................................ 15% Pulse Width............................................................... 8 milliseconds CW Minimum .................................................................. 1200 watts Low Range ....................................................................... 100 watts nominal FLATNESS, high range ................................................... 1.5 dB FREQUENCY RESPONSE.............................................. 10 kHz - 220 MHz instantaneously INPUT FOR RATED OUTPUT ....................................... 1.0 milliwatt maximum GAIN (at maximum setting) High Range............................................................. 61 dB minimum Low Range.............................................................. 47 dB minimum GAIN ADJUSTMENT (continuous range) ....................... 18 dB minimum INPUT IMPEDANCE ...................................................... 50 ohms, VSWR 1.5:1 maximum OUTPUT IMPEDANCE................................................... 50 ohms, nominal MISMATCH TOLERANCE* ........................................... 100% of rated power without foldback.
