The Keysight 547A hand-held current tracer provides a fast, easy, and economical way to troubleshoot wired-AND buses and three-state buses to pinpoint the one bad IC on a stuck node, locate hairline solder bridges, or find backplane and motherboard shorts.
The 547A precisely locates low-impedance faults in digital circuits by locating current sources or sinks, and troubleshoots circuits carrying fast rise-time current pulses. Using a one-light indicator, the 547A displays transitions, single pulses, and pulse trains. Because it is not voltage-sensitive, the tracer operates on all logic families with current pulses exceeding 1 mA, including CMOS, where even lightly-loaded outputs can have up to 2 to 3 mA of instantaneous charging current.
- Wide dynamic range
- Fingertip indicator
- Sensitivity to follow traces in multilayer boards
- Stretching for single current pulse display

- Risetime: Light indicates current transitions with risetimes <,=200 ns at 1 mA
- Voltage: 4.5 to 18 Vdc
- Input Current: <,=75 mA
- Maximum Ripple: ±500 mV above 5 Vdc
- Overvoltage Protection: ±25 Vdc for one minute
- Temperature: 0° to 55° C
