FUNCTION GENERATOR - AMPLIFIER - FREQUENCY COUNTER (0686) A reasonably priced, feature rich apparatus incorporating three functions into a single instrument with 4 digit, 7 segment LED display. Its simple and well organized operating panel makes it well suited for demonstration experiments by the teachers as well as for use by the students for experiments in vibrations, waves and much more. Function Generator: Provides three type of output waveforms - sine, square and triangular with a broad continuous frequency range of 0.1Hz to 100kHz with output impedance of 600Ω and maximum output amplitude (Vpp) of 20V (peak-to-peak). Also provided with digital fine tuning of both frequency as well as amplitude with frequency readout available on the digital display. The BNC output signal connection is short circuit protected. Also allows the demonstration of frequency modulation by connecting an external signal. DC Amplifier: Also incorporated is a 10W amplifier, short circuit protected, and has a frequency range from 0-50kHz with maximum input of ?50V it can also be used to. amplify signals from the function generator or from external sources. The input of external signals is by means of a BNC connector with an impedance of 10kΩ and the output signal is accessible through safety-type 4mm colour coded shrouded banana jack connectors, Frequency Counter: Provides a fully automatic measurement of external frequencies from 0.1Hz to 150kHz, which can be read directly from the 4digit digital display. The apparatus operates on 220-240V AC, 50Hz. Supplied complete with detachable 3-core mains lead and user instruction manual. Qty :
