MODEL 663 VIBRATION AMPLIFIER

Description

The Model 663 is a combination amplifier and integrator for accelerometer signals. One integration stage is provided, converting acceleration into velocity. The unity gain
frequency of the integrator is factor-trimmed to 60Hz. Two outputs are provided per accelerometer–a buffered copy
of the acceleration, and the integrated velocity output. Prior to the integration stage, a gain of ten may be applied with a front-panel toggle switch. The Model 663 is a two-channel module, providing signal conditioning for two accelerometers, giving a total of 16 channels in a 5.25" high 19" rackmount.
