Digital Oscilloscope

A two channel digital storage oscilloscope (Gould 1602) with a sampling speed of 20 Ms/sec and an operating frequency range of 0 20 MHz has been used. The Gould 1602 can operate in storage as well as non-storage mode. In the former, it has a sampling speed of 2 MHz. The oscilloscope has been used for square wave testing of the hotwire anemometer.
