Waveform Viewer Scope Kit

by Galak Electronics
Part No. VG-102
Shipping Weight: 1.0 ounces (30 grams)

With three time scales and two voltage inputs levels, the Waveform Viewer Scope is capable of measuring frequencies from 1 hertz to 15 kHz and voltages from 100 mV to 10V. It also includes an adjustable voltage offset for true AC voltages, yet operates on a single supply. With a 100 LED high intensity display and lots of adjustments, this kit is a great educational tool and a must have for electronics students, hobbyists or amateur engineers.

The unassembled kit includes instructions (including schematic and parts placement) and all the components to build one complete Waveform Viewer Scope. A soldering iron, solder and a pair of cutters are required for assembly.
