Description
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.
