An active oscilloscope probe is a type of probe that uses an internal amplifier circuit to measure signals, instead of relying only on cable resistance and a passive design, as traditional probes do.

Active probes are useful for measuring high-frequency or weak signals, where passive probes can introduce too much loading or attenuation into the system under test. This makes them especially well suited to applications that require precise analysis of fast, high-impedance signals, such as high-speed electronics, communications, or digital circuits.

The AP020 FET probe extends the measurement capabilities of any oscilloscope. It provides higher resistance, lower capacitance, and a flatter system bandwidth than passive probes. The reduced loading on the circuit under test results in more accurate measurements. FET probes are the ideal tool for working on sensitive or high-speed electronic components.
