LED indicator for easy verification of program modes and operation
The HP Agilent 546A logic pulser stimulates digital integrated circuits (ICs) in-circuit -- no trace cutting or unsoldering of IC outputs is required. Touch the pulser to the circuit under test, press the pulse button, and all circuits connected to the node (outputs as well as inputs) are briefly driven to their opposite state. Pulse injection is automatic, high nodes are pulsed low, and low nodes high each time the button is pressed.
