Mini-lab 603B

A most versatile instrument which combines a 0.001 Hz to 2MHz function generator with a 7W DC coupled power amplifier, an op-amp, sweep ramp generator and 3 DC power supplies. Inputs and outputs are quite independent or may be linked for a multitude of uses. The Function generator has variable ramp and pulse output, two levels of attenuation and may be swept over a 100: 1 range by its internal sweep ramp generator.
The Power amplifier which extends from DC to >80kHz also doubles as a 1 amp, bi-polar or voltage controlled power supply or as a fixed +5V 1 amp supply.

FUNCTION GENERATOR
Range: 0.01 Hz to 1 M H z in 8 decade ranges. Plus, an additional 200kHz to 2MHz range. Uncalibrated range extends to 0.001 Hz.
