The realization method of double-line oscilloscope

In the daily use of oscilloscopes, people often use the two-line oscilloscope of oscilloscopes. Do you know how the two-line oscilloscope of oscilloscopes is realized? The following experts from China Sensor Trading Network will introduce to you the implementation method of the two-line oscilloscope of oscilloscopes.

In the process of electronic practice, it is often necessary to simultaneously observe the process of two (or more) signals changing over time.

And the electrical quantities of these different signals are tested and compared. In order to achieve this goal, people use the following two methods to display multiple waveforms simultaneously based on the application of the principle of ordinary oscilloscopes: one is the two-line (or multi-line) oscilloscope method;

The other is the dual-trace (or multi-trace) oscilloscope method. The oscilloscopes made using these two methods are called dual-line (or multi-line) oscilloscopes and dual-trace (or multi-trace) oscilloscopes respectively.

The two-line (or multi-line) oscilloscope is realized by using a two-gun (or multi-gun) oscilloscope tube. The following is a brief explanation using a two-gun oscilloscope tube as an example.

The double-gun oscilloscope has two independent electron guns to produce two beams of electrons. There are also two independent deflection systems, each of which controls a beam of electrons to move up and down, left and right.

The fluorescent screen is shared, so two different electrical signal waveforms can be displayed on the screen at the same time, and the dual-line oscilloscope can also be realized by using a single-gun dual-line oscilloscope tube.

This oscilloscope tube has only one electron gun, which relies on special electrodes to separate electrons into two beams during operation. Then, two independent deflection systems in the tube control the two beams of electrons to move up and down and left and right, respectively.

The fluorescent screen is shared and can display two different electrical signal waveforms at the same time. Due to the high manufacturing process requirements and high cost of the two-wire oscilloscope, its application is not very common.

The above is an introduction to the implementation method of the dual-line oscilloscope of the oscilloscope. I hope everyone can have a comprehensive understanding of the above knowledge.
