The Tektronix P6230 is a passive ×10 (450:50 Ω) probe with 1.5 GHz bandwidth and DC offset capability, intended to minimize probe-loading effect when used on logic circuits.

It can be powered from 7000 series mainframes having LEMO S-series connectors for probe power, or compatible units such as the 1101.

The P6230 is sometimes described as a FET probe or an active probe, however, as the circuit diagram clearly shows, this is not the case. The input signal runs through a 400 Ω resistor and a 1 μF capacitor, terminated in 50 Ω internally (switchable) or externally. The active circuit in the P6230, a standard NE5532 dual opamp, has the function of restoring and offsetting the input signal's low-frequency and DC components, similar to the feed-beside technique used in the 7104 scope and 7A29 amplifier.

It shares accessories with many other Tektronix subminature modular probes although the input hybrid is unique. Tip color is yellow, connector end color is blue, part number 206-0279-00. Its end to end resistance is 400 Ω.
