TM 50MHz Logic Probe & Pulser Description The Logic Pulser is a very effective tool for inspecting and repairing the logic circuits. It can be used directly to inject a signal into the logic circuits without removing the IC or breaking the circuits. The 100mA pulse output insures that the device under test will be pulsed, while the short 10μs duration of the output pulse makes sure that no damage will be done to the circuit under test. The logic Pulser output is changeable between 0.5 and 400Hz, making it suitable for use with either a logic probe or with an oscilloscope, also has an external sync input, which enables the user to synchronize the pulse output with an external signal, such as a computer clock circuit. Operation: a. Attach red alligator clip to positive side of DC, power supply of printed circuit board under test. b. Attach black alligator clip to negative side of DC, power supply of printed circuit board under test. c. Setting the repetition rate switch to 0.5pps or 400pps.
