In general, a probe is a device that detects the signal to be measured and transmits it to a measuring instrument when observing a waveform, and a logic probe is positioned as a special probe among these probes.
Logic probes are sometimes used for scopecoders, which are integrated measurement instruments, and mixed-signal oscilloscopes, which can also handle RF signals, analog and digital. Proper use of probes is important for accurate measurements.
Logic probes are generally supplied with oscilloscopes as specialized probes suitable for that oscilloscope, and are used for the detection and transmission of the target signal when observing waveforms, which is why logic probes are classified as special probes.
Logic probes are available in a lineup with added features such as the presence or absence of insulation, high-speed transmission, etc., according to the application.
The probe is characterized by its ability to detect signals and transmit signals while functioning as part of a measuring instrument. For this reason, the probe's output impedance, frequency, voltage, current, amplitude, and other values that the probe has may affect the measurement, requiring an understanding of the signal to be measured and the characteristics that the probe has.
Having the right probes for your oscilloscope is very important to making accurate measurements, which is why oscilloscopes come with dedicated probes.
Many failures in digital systems are due to the analog characteristics of digital waveforms, and in order to analyze the analog cause, it is necessary to observe specific pulses, which requires the functionality of a logic analyzer. To meet this need, logic probes are designed with compatible logic circuits and are capable of both synchronous and asynchronous operations.
