How to remotely control and distinguish oscilloscopes and oscilloscope probes?

An oscilloscope is a type of electronic test instrument. It is mainly used to display and measure the waveform and voltage of electrical signals. The oscilloscope probe is the connection between the oscilloscope and the circuit to be measured. It is used to transfer the voltage signal of the circuit to the oscilloscope for display and measurement. Oscilloscopes and oscilloscope probes can be remotely controlled in a variety of ways, and there are some differences between the two. The remote control methods of oscilloscopes and oscilloscope probes will be introduced in detail below and distinguished between them.

Remote control means that the oscilloscope and oscilloscope probe can be operated and controlled from a distance through certain methods and means without direct contact with the oscilloscope and oscilloscope probe.

1. Remote control method of oscilloscope:

1. Control via computer: Most modern oscilloscopes have USB, Ethernet, GPIB and other interfaces. You can connect the oscilloscope to the computer through these interfaces, and then use specialized software or programming languages ​​(such as LabVIEW, Python, etc.) for remote control. Users can set various parameters of the oscilloscope on the computer, including trigger conditions, time and voltage measurement, and data collection and storage.

2. Control through wireless communication: Some modern oscilloscopes also provide wireless communication functions, such as WiFi, Bluetooth, etc. Users can remotely control the oscilloscope through mobile devices or specialized wireless controllers to adjust parameters, measure and other operations.

3. Remote control through web pages: Some oscilloscopes support the WEB server function, and users can access the web pages inside the oscilloscope through a browser, thereby achieving remote operation and monitoring without client software.

2. Remote control method of oscilloscope probe:

An oscilloscope probe is a device that connects the circuit under test to an oscilloscope. It is mainly used to transmit circuit signals to the oscilloscope for measurement. Since oscilloscope probes usually provide large input impedance and small interference to the circuit under test, appropriate wiring methods and parameters need to be designed.

Oscilloscope probes usually do not have independent remote control functions, but parameters such as probe attenuation ratio, compensation, and grounding method of the ground wire can be remotely controlled through the oscilloscope.

1. Remote control of wiring methods: Oscilloscope probes generally include ground wires, signal wires, and power wires. The oscilloscope can set the probe's grounding method through remote control, including single-point ground, floating ground, and common ground.

2. Remote adjustment of control parameters: The oscilloscope probe can also remotely adjust the attenuation ratio and compensation through the oscilloscope. Through remote control, the oscilloscope can set or automatically detect the attenuation ratio and compensation value of the probe to adapt to different measurement applications.

3. The difference between oscilloscope and oscilloscope probe:

1. Different functions: An oscilloscope is an instrument used to display and measure electrical signal waveforms and voltages. It is mainly used to analyze and monitor the characteristics of circuit signals. The oscilloscope probe is the connection device between the oscilloscope and the circuit under test, used to transmit the circuit's signal to the oscilloscope.

2. Different control methods: The oscilloscope can be remotely controlled through a variety of methods, including computer control, wireless communication and web page remote control. Oscilloscope probes usually do not have independent remote control functions, and their parameter adjustment usually requires remote control through an oscilloscope.

3. Different application scopes: Oscilloscopes are widely used in electronics, communications, automation and other fields, and can measure and analyze signals from various circuits. The oscilloscope probe is mainly used to transmit the signal of the circuit under test to the oscilloscope for measurement, and is an important part of the oscilloscope measurement system.

To sum up, oscilloscopes and oscilloscope probes can be remotely controlled through computer control, wireless communication and web page remote control, but their functions and application scope are different. The oscilloscope is used to display and measure the waveform and voltage of electrical signals. The oscilloscope probe is mainly used to connect the oscilloscope and the circuit under test and transmit the circuit signal to the oscilloscope for measurement. Through remote control, the parameters and measurement range of the oscilloscope can be easily adjusted to achieve more flexible and convenient measurement and analysis.
