30 MHz (With Frequency Counter) Analog Oscilloscope
Description
Analog oscilloscope, which adopts cathoderay tubes to display a waveform, is the first oscilloscope that is used by engineers. The screen’s photoluminescent phosphor illuminates every time an electron hits it. A representation of signal is displayed as successive bits of phosphor light up, while a trigger makes the displayed waveform appear stable. Upon completing an entire trace of the display, the oscilloscope waits until a particular event occurs and begins the trace again. 30 MHz analog oscilloscope is widely used in science, pharmacy, engineering and telecommunication industries.
Advantages
1. Equipped with frequency counter, this 30 MHz analog oscilloscope has high vertical resolution which is also continuous and unlimited.
2. It is simple to operate. All the operation processes are completed in the faceplate so that the waveform responses in a quick manner.
3. 30 MHz analog oscilloscope with frequency counter is fast in data update because it captures hundred and thousand of waveforms per minute.

Notes
1. 30 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 and use a soft cloth with mild detergent and water instead.
- 40MHz Analog OscilloscopeAnalog 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...
