An oscilloscope is vital electronic device equipment that is generally used in the testing or laboratory arena of the electronic hardware industry. This device displays the voltage waveform during the testing of the device. However, without an oscilloscope probe, it’s just a fancy electronic device.

What is an oscilloscope probe?

Oscilloscope probe is a device whose one end is connected to the input of oscilloscope and the other one is tipped to the electronic device/signal source under testing. Manufacturers ensure that their oscilloscope probe has minimal signal source loading and have sound noise immunity for better measurement. Moreover, they also ratify that the signal which gets picked by the probe tips gets duplicated successfully at the oscilloscope.

There are various types of probes which depend on the measurement and the usage of the oscilloscope. Here below are some popular types of oscilloscope probe:

  • Active Voltage Probe

When an engineer needs to deal with higher bandwidth, they usually consider active voltage probe. They have a lower input voltage range as compared to the passive voltage probe. It generally relies on the transistors for the operation which are also called field-effect transistors (FET). Active voltage is generally more expensive than passive voltage probes.

  • Passive Voltage Probes

This type of probe is available in various attenuation factors-1X, 10X, and 10X, which varies according to the needs. At present, a 10X passive voltage probe is the most supplied probe with the oscilloscopes. It does not rely on any active component such as amplifiers of transistors for the operation. As compared to the active voltage probe, it has a higher voltage range They are used for browsing bugs and other qualitative measurements.

  • Differential Probes

A differential probe has two different inputs: positive and negative, which results in a differential signal for the measurement of the oscilloscope output channel. It is usually utilized for broader frequency range and where signals are referenced to each other; for example, power line noise. It uses a differential amplifier to convert the difference between two signals.

  • Current Probes

Current probes use the Hall effect sensor to convert the current flowing in the conductor into the voltage. This type of probe helps in exploring both DC and AC circuits without fracturing the network integrity. Generally, AC probes used transformer technology to sense the strength of the electromagnetic field. It can measure high current range without comprising on accuracy.

There are also other oscilloscope probes such as optical probes, isolated probes, and logic probes, among others, available in the market.
