What does the isolation of oscilloscope mean?

Isolated oscilloscope, between channels, each channel is isolated from each other and other non-isolated devices at the same time. The isolated oscilloscope is usually equipped with a specially designed passive probe, and its connection on the BNC buckle is insulated to prevent electric shock. Isolated oscilloscope is the front-end circuit of isolated oscilloscope and the acquisition system behind AD, which is suitable for low voltage, good signal accuracy and low distortion.

Differential probes are generally suitable for high voltage and have absolute safety advantages. In addition, the differential probe can improve the measurement quality, provide a balanced measurement input capacitance, and can safely measure the voltage between any points in the circuit. Compared with the isolated oscilloscope, it is different to test the voltage and waveform to maintain the reduction and test the noise. High voltage differential oscilloscope and low voltage isolated oscilloscope. But it is not absolute, it depends on the specific test environment. The differential probe can be applied to floating voltage measurement, high voltage or high voltage isolation measurement, switching power supply design, UPS power supply, frequency converter, electronic ballast design, motor drive design, induction heating, induction cooker, electrician experiment and electric drive experiment.
