MODEL 643 COMPUTER-CONTROLLED PRECISION AMPLIFIER
- Precision gains
- Differential input
- Remotely controllable
- Eight channels per rack
Description
The Model 643 is an eight-channel remote-controllable precision gain differential amplifier with three highly-accurate switch selectable gains of 100, 200, and 500. Under remote control, each channel's input can be shorted for zero measurement and the front panel gain select can be overridden. Three lowpass filters are also front panel selectable.
