Targeted current analysis

The Pintech PT-3225A is a high-frequency AC/DC current probe built for engineers and technicians who need precise waveform capture on an oscilloscope. It handles DC through 25 MHz bandwidth with a 500 A peak range and ±1 % accuracy. A standard BNC connector makes it compatible with any oscilloscope, while the 20 mm jaw opening fits most conductors encountered in power-electronics or automotive diagnostics.

Sustained measurement behaviour

Under continuous load the probe maintains its stated 1 % accuracy across both 10:1 and 100:1 transformation ratios. Noise stays at 20 mA rms, and the 14 ns rise time ensures fast transients are not smeared during long acquisitions. RMS ratings of 17 A on the low range and 170 A on the high range mean the device runs within spec during extended sessions without thermal drift or saturation.

Upgrade path and limits

This probe replaces lower-bandwidth clamp meters or fixed-range probes that cannot resolve fast switching edges above a few megahertz. The jump is worthwhile when you need both DC and AC coupling up to 25 MHz and a 500 A peak capability in one handheld unit. It is not suited for buyers who require higher bandwidth, greater peak current, or a smaller jaw diameter for dense wiring harnesses.

Questions about this item

How much heat or noise does the PT-3225A produce when clamped on a conductor for a full day?

The probe draws only 20 mA rms of noise current and has no fan or active cooling, so it runs silently and stays at ambient temperature during continuous use.

What must I already own to use the PT-3225A with my oscilloscope?

You need an oscilloscope with a standard BNC input; the probe includes a BNC cable and two selectable ratios of 100 mV/A and 10 mV/A for direct connection.

Will the PT-3225A work with an older analog oscilloscope that only goes to 10 MHz?

Yes, the probe operates from DC to 25 MHz with a 14 ns rise time, so it will pass signals cleanly into a 10 MHz scope; just select the 10 mV/A range for up to 500 A peak.
