Pearson Electronics

Pearson Electronics

Pearson Electronics is a US-based manufacturer with a long-standing specialization in wideband current monitors and current probes for pulse and high-frequency measurement applications. Founded in 1955 and based in Palo Alto, California, Pearson is highly regarded in the power electronics, EMC testing, and pulsed power research communities for the accuracy and broad bandwidth of their current measurement products.

Pearson current monitors are passive, toroidal transformer-based instruments that convert current waveforms into voltage signals measurable by oscilloscopes. They are widely used where conventional active current probes cannot perform — particularly in high-voltage, high-current, or fast-rise-time environments such as plasma physics research, particle accelerators, power converter characterization, and high-power switching circuit testing.

Key Product Lines

• Wideband current monitors — passive toroidal probes for oscilloscopes covering frequency ranges from low Hz to hundreds of MHz
• High-current probes — models rated for hundreds to thousands of amperes for power pulse and pulsed power measurement
• Precision current transformers — for EMC testing, power electronics characterization, and scientific research applications

Industries Served

Pearson Electronics products are used in university and government research laboratories, national laboratories including DOE and DoD facilities, EMC test labs, power electronics design centers, semiconductor manufacturing, and high-voltage test environments. Their monitors are a standard tool in pulsed power research and particle accelerator physics.
