Siglent CP6030 50 MHz 50Amp Current Probe
The new Siglent CP6030 Current probe with 50 MHz Bandwidt a maximum continuous current 30 Arms; Peak current 50 A; Switching ratio: 5 A/30 A; Accuracy: 5 A(±1%±1mA); 30 A(±1%±10mA); Standard DC12 V / 1 A power adapter
50 A active current probe, DC–50 MHz
The CP6030 is an active split-core current probe with ±1% accuracy and 50 MHz of bandwidth, rise time ≤7 ns. The 5 A range resolves down to 1 mA, which is what makes small-signal current work possible on the same probe you use for the power stage.
It runs from its own 12 V adapter and connects over BNC, so it works with any oscilloscope of any brand — unlike the SAPBUS-powered SCP5000 equivalents, which need a recent Siglent scope. Two ranges (5 A (1X) and 30 A (10X)) cover small and large currents, with over-current indication on each.
What it does well
The things that decide whether a current measurement can be trusted.
±1% accuracy
Far tighter than any handheld clamp, and the reason these probes are used for efficiency and switching-loss measurement where the number itself has to stand up in a report.
50 MHz bandwidth
Rise time ≤7 ns. Fast enough to show the current edge itself, not just the envelope it sits in.
5 mm jaw, 255 g
Small enough to clamp a single lead on a crowded board, and light enough to leave hanging on the wire while you set the scope up.
Works with any oscilloscope
Its own DC 12 V supply and a plain BNC output. No proprietary probe bus, so it is not tied to one brand or one generation of scope.
Split core, no circuit broken
Clamp around the conductor and the circuit stays intact — no shunt inserted, no burden resistance added to the thing you are characterising.
Over-current indication
Warns at ≥5 A on the low range and ≥50 A on the high one, so a saturated core gets noticed rather than quietly distorting the waveform.

Application examples
Switching and linear power design
Switch-node and inductor current with the accuracy to turn a V×I product into a real loss figure. Pair with the DF2001A to null probe-to-probe skew first.
Semiconductor and gate-drive work
Device current through turn-on and turn-off, where all the energy is in the transition and bandwidth decides whether you see it at all.
DC-DC converter development
Ripple and transient current on a fast converter, resolved down to milliamps on the 5 A range.
Lighting and appliance electronics
LED driver current, frequency-conversion appliances and electronic ballast design.
