MODEL 1000L

1200 WATTS CW

2500 WATTS PULSE

10kHz-220 MHz

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.
