LOGIC PULSER

The K&H LP-540H logic pulser is a very effective tool for inspecting and repairing logic circuits. It can directly inject a signal into the logic circuits neither removing the IC nor breaking the circuits. Using the logic probe as a monitor, you not only know the wiring errors but also check out mal-functional components.

Logic Pulser can produce a 10µs pulse signal at 100 mA load. The signal frequency can be switched to either 0.5Hz or 400Hz as a result the LP-540H is a fairly powerful pulser.

Moreover, the Logic Pulser can produce a 90% high digital signal at square wave output terminal. It is easier to observe and trace circuits by using oscilloscope. With a sync. input, it’s able to produce an external synchronized signal.
