Logic Probe & Pulser

The GLP-1A logic pulser can be used to perform in-circuit testing of TTL, CMOS, and many other logic devices at a maximum of 50MHz. The GLP-1A is enhanced with a logic probe function with a minimum detectable pulse width of 10 ns, providing enough sensitivity for most applications. A Short 10 sec pulse width assures that no damage will occur to circuits whilst testing. With a weight less than 50g, a non-slip grip, and an external sync input, GLP-1A provides comfort and reliability for various troubleshooting tasks.
