The Tektronix P6021A and P6022 are AC current probes that provide versatile AC current measurements over a wide range of frequencies. Both probes clip onto a current-carrying conductor, allowing current measurements without breaking the circuit. The shielded probe heads are not grounded when the slides are in their open positions, which eliminates accidental grounding of the circuit under test. Both use split-core construction for easy circuit connection and are intended for 1 MΩ inputs, measuring AC only.

An AC current probe lets an engineer measure alternating current non-invasively by clamping around a conductor rather than inserting a shunt into the circuit. Listed applications for these probes include motor drives, power inverters and converters, power supplies, and avionics.

ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois.

Brand Heritage

Tektronix, founded in 1946, was acquired by Danaher Corporation in 2007 and became part of Fortive Corporation when Fortive was spun off from Danaher in 2016.

Compare Other Models in This Series

The Tektronix P6021A and P6022 form a two-probe family of AC current probes, both providing versatile AC current measurements over a wide range of frequencies. Each probe clips onto a current-carrying conductor for measurements without breaking the circuit, and both use split-core construction with a shielded probe head that is ungrounded when the slides are open.

Within the family, the P6021A is intended for general-purpose applications with wide-band performance and excellent low-frequency characteristics, while the P6022 has a probe head about half the size, suited to measuring currents in compact, high-performance circuits.

Each new model in this family is listed on its own product page with condition-matched pricing. Select the model that fits your bandwidth, current, and conductor-size requirements; the comparison below summarizes how the two probes differ.

For general-purpose applications, the P6021A provides wide-band performance from 120 Hz to 60 MHz with excellent low-frequency characteristics. Its range is switchable between 2 mA/mV and 10 mA/mV, and its probe head accepts conductors up to 5 mm in diameter.

The two probes differ across several headline parameters summarized in the comparison table. The P6021A covers 120 Hz to 60 MHz and is rated 10.6 A RMS, 250 A peak with 10 mA sensitivity; the P6022 covers 935 Hz to 120 MHz and is rated 4 A RMS, 100 A peak with 1 mA sensitivity.

They also differ physically: the P6021A head measures 20 cm by 16 mm by 32 mm and accepts conductors up to 5 mm, while the P6022 head is roughly half the size at 152 mm by 6.4 mm by 12 mm, accepting conductors up to 2.8 mm. The P6021A range switches between 2 and 10 mA/mV, while the P6022 passive termination output switches between 1 and 10 mA/mV.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Product Core & Specifications

Important: Maximum conductor diameter: 5 mm (P6021A) and 2.8 mm (P6022).

Important: Shielded probe heads are not grounded when the slides are in their open positions, eliminating accidental grounding of the circuit under test.

Important: These are AC-only current probes for 1 MΩ inputs; current measurements are made by clipping onto the current-carrying conductor without breaking the circuit.

Recommended pairing: use the deskew/calibration fixture (067-1686-xx) and the 1-turn 50 Ω current loop with BNC connector (067-2396-xx) listed in the recommended accessories for deskew and performance verification.
