What is a Passive probe?

A passive probe is a common measurement tool used to measure signals, which does not require an external power source and directly receives signals from the measurement target. This type of probe is typically connected to an oscilloscope or other measuring instruments and is used to measure both high-frequency and low-frequency signals. Passive probes generally have very high input impedance, which minimizes the load on the signal source. This allows for accurate measurements without significantly affecting the signal being measured. Many passive probes are used to faithfully measure the waveform of signals and display them on oscilloscopes.

Application of Passive probe

✅ Signal Measurement with an Oscilloscope
A passive probe is used to connect to an oscilloscope for accurately measuring electrical signals and waveforms. It is used to measure a wide range of signals, from high-frequency to low-frequency signals, with precision.
✅ Measurement of Microwave Circuits
Passive probes are also used to measure signals in microwave or high-frequency circuits. This allows the faithful observation of signal waveforms and helps assess the characteristics of the circuit.
✅ Power Supply Monitoring
Passive probes are used in power supply systems to monitor voltage and current waveforms. They provide valuable information to maintain stable operation of the system.
✅ Debugging Electronic Devices
Passive probes are commonly used for fault analysis and debugging of electronic devices. By observing the signal waveforms, it is possible to identify and correct faulty components.
