An oscilloscope, a benchtop instrument, graphically displays electrical signals and shows how those signals change over time. They are used by engineers to troubleshoot circuits and check signal quality. Most engineers use digital oscilloscopes. Digital oscilloscopes are used to acquire and store waveforms, display the voltage, frequency, noise portion of the signal, detect whether the signal is distorted, the time interval between signals, etc. But when it comes to choosing an oscilloscope, how do you know which oscilloscope is right for you? The following 7 factors need attention.

Digital oscilloscope has the unique advantages of waveform triggering, storage, display, measurement, waveform data analysis and processing, and its use is increasingly popular. It is an indispensable tool for designing, manufacturing and repairing electronic equipment. Digital oscilloscope generally support multi-level menu, can provide users with a variety of choices, a variety of analysis functions. Other oscilloscopes can provide storage for waveform storage and processing. In this article we are going to discuss about different types of digital oscilloscopes in detail.

Digital oscilloscope is a high performance oscilloscope manufactured by A series of technologies such as data acquisition, A/D conversion and software programming. It is an indispensable tool for designing, manufacturing and repairing electronic equipment. Digital oscilloscope generally support multi-level menu, can provide users with a variety of choices, a variety of analysis functions. Other oscilloscopes can provide storage for waveform storage and processing. In this article, we will show you the ATO's oscilloscope price list.

An oscilloscope is a very versatile electronic measuring instrument. It can transform invisible electrical signals into visible images, which is convenient for people to study the changing process of various electrical phenomena.Today we will introduce the features and applications of oscilloscopes. We hope that after reading, you can know the usage of oscilloscope.

Bandwidth is one of the most important indexes of oscilloscope. The bandwidth of analog oscilloscope is a fixed value, while the bandwidth of digital oscilloscope has two kinds: analog bandwidth and digital real-time bandwidth. The maximum bandwidth that digital oscilloscope can achieve by using sequential sampling or random sampling technology for repeated signals is the digital real-time bandwidth of oscilloscope. The digital real-time bandwidth is related to the maximum digital frequency and waveform reconstruction technology factor K (digital real-time bandwidth = maximum digital rate / k), which is generally not directly given as an index. 

Digital oscilloscope is an indispensable tool for the design, manufacture and maintenance of electronic equipment. With the rapid development of technology and market demand, engineers need the best tools to quickly and accurately solve the measurement challenges. As the eyes of engineers, digital oscilloscope is very important to meet the current difficult measurement challenges. Because of the unique advantages of waveform trigger, storage, display, measurement, waveform data analysis and processing, digital oscilloscope is widely used. Due to the large performance difference between digital oscilloscope and analog oscilloscope, if used improperly, it will produce large measurement error, thus affecting the test task.

The oscilloscope probe is mainly used to guide the measured voltage signal from the measuring point into the oscilloscope for measurement. Probe is crucial to the accuracy and correctness of the measurement results, as it's the electronic component connecting the measured circuit and the input of the oscilloscope. The simplest probe is a wire that connects the measured circuit and the input of the oscilloscope, a complex probe consists of resistor-capacitor unit and active devices. A simple probe has no shielding measures, so it's susceptible to external electromagnetic interference. Meanwhile, larger equivalent capacitance in it would increase the load on the measured circuit, thus leading to distortion of the measured signal.

There is no signal waveform on the screen when collecting signals?
1. Check whether the detector is normally connected to the signal wire.
2. Check whether the signal wire is normally connected to the BNC (namely channel connector).
3. Check whether the detector is normally connected with the object under measurement.
4. Check whether the object under measurement produces a signal (Signal channel can be connected with the fault channel to find out the fault).
5. Collect the signal again.
6. Check the state of the trigger mode.
