40MHz Analog Oscilloscope
Description
Analog oscilloscope, which employs cathoderay tubes to display a waveform, is the first oscilloscope that is used by engineers. It uses electronic gun to emit electrons to the screen. The emitted electrons form into electron beam by focusing. Then the electron beam is irradiated to the screen coated with fluorescent material and gives out light. It shows the signal waveform by inputting signal to control the deflection of electron beam. 40 MHz analog oscilloscope is widely used in science, pharmacy, engineering and telecommunication industries.
Advantages
1. 40 MHz analog oscilloscope is simple to operate. All the operation processes are finished in the faceplate so that the waveform responses in a quick manner.
2. Analog storage oscilloscope has high vertical resolution which is also continuous and unlimited.
3. It is fast in data update because it captures hundreds and thousands of waveforms every minute.
4. 40 MHz analog oscilloscope provides visible waveforms to the technicians who can take tests easily within the regulated bandwidth.

Maintenance
1. Keep regular cleaning so as to maintain good ventilation of analog oscilloscope.
2. Do not spray cleaner directly onto the instrument when cleaning it. Please use a soft cloth with mild detergent and water instead.
