20 MHz Analog Oscilloscope
Description
Oscilloscopes are used to observe the change of an electrical signal over time. The constantly varying signal voltages can be graphed on the screen, which is commonly referred to as a waveform.
Application
1. 20 MHz analog oscilloscope with probe is widely used in science, medicine, engineering and telecommunication industry.
2. It can also be used to test different powers such as voltage, electric current, frequency, phase difference and amplitude modulation.
Features
1. 20 MHz analog oscilloscope is simple to operate. All the operation processes are completed in the faceplate so that the waveform responses in a quick manner.
2. It 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 per minute.
4. It provides visible waveforms to the technicians who can take tests easily within the regulated bandwidth.

Notes
1. 20 MHz analog oscilloscope should be equipped with suitable line voltage.
2. To avoid electrical shock, the protective grounding conductor of power cord should be connected to ground.
Maintenance
1. To maintain good ventilation, regular cleaning should be carried out.
2. Do not spray cleaner directly onto the instrument when cleaning it. Please use a soft cloth with mild detergent and water instead.
- 20 MHz (With Frequency Counter) Analog OscilloscopeAnalog oscilloscope is used to observe the change of an electrical signal over time. 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 which...
