This circuit-powered, logic pulser is used to perform in-circuit testing of TTL, CMOS, and many other logic devices. A 100mA pulse output assures that the device under test will be pulsed, while the short 10ms pulse duration assures that no damage will occur to the circuit under test. Pulse repetition rate is switchable between 0.5 and 400 pulses/sec., making it suitable for testing in tandem with either a logic probe or oscilloscope. An external sync input enables the user to synchronize pulse output with an external signal such as a computer clock circuit. An external square wave terminal is also provided. Size: 8.2"L x 0.7"W x 0.7"D. Weight: 1.4 oz.
