OSCILLATION IN AMPLIFIERS

OSCILLATION IN AMPLIFIERS Most amplifiers work without problems, but in some cases oscillations may occur with high frequencies/high gains and/or poor layout. The first step is to measure the frequency and amplitude of the oscillation. Use the internal triggering of

Model 755A-04.1

Hybrid eyesafe laser rangefinder receiver is designed for laser rangefinding & surveying equipment. Compact construction is ideal for miniature applications. Fast recovery from To overload allows ranging to close objects without compromising long range performance. The incorporation of an InGaAs APD gives very high sensitivity with time programmed gain to minimize false targets. Operation at both 1.06 µm and 1.54 µm is possible over a wide range of pulse widths.
