LP540H Logic Pulser is a low-cost item of test equipment. As the name indicates, a logic probe tester is used for probing and analyzing logic circuits.
A logic probe tester is normally a small item of test equipment, typically handheld in the form of what could be thought of as a large oscilloscope probe, but without the lead.
This makes logic probes very portable and easy to use for troubleshooting and general simple maintenance work on low-complexity logic circuitry.
For most applications, a LP540H Logic Pulser would not be used within a laboratory test environment – here more sophisticated test equipment would be used because much closer investigation of problems is required.
