About This Product
On its own, the microphone is not suitable for producing a trace on an oscilloscope, so its signal is boosted through a Power Amplifier before reaching the oscilloscope. A pair of these microphones used with the Fast Timer allows the speed of sound practical to be carried out. Besides buyers across India, the Crystal Microphone can be exported to institutions in Barbados, Laos, Vanuatu, France and Brunei.
Frequently Asked Questions
Q1. Can it be connected directly to an oscilloscope? Not on its own. It must be connected to the oscilloscope via a Power Amplifier to boost the signal so that a trace is seen.
