The LP-540H Logic Pulser is an active troubleshooting instrument used to force digital nodes into high or low logic states safely. Generating 10Β΅s pulses at up to 100mA sink/source current, it overcomes low-impedance node drive without damaging surrounding circuit components. With selectable pulse rates 00.5Hzsingle-pulse mode and 400Hz continuous tone mode) plus an external synchronization input, it is an invaluable companion for hardware repair labs, microcontroller debugging, and digital logic training.
Key Features
In-Circuit Signal Injection: Directly injects clean digital pulses into IC pins and circuit traces without removing components.
Dual Frequency Switching: Easily switch between 0.5Hz (slow single step tracing) and 400Hz (high-speed continuous pulse stream).
High Output Drive Capability: Delivers 100mA sink/source current to momentarily override active gate outputs without causing thermal damage.
External Sync Input: Features an external synchronization input to trigger injected pulses in lockstep with external clock signals.
Onboard Protection: Integrated overvoltage protection on power leads and signal probe tip ensures safe operation on active boards.
