An output gate is connected to four input gates; the circuit does not function. Preliminary tests with a DMM indicate that power is applied; scope tests show that the primary input gate has a pulsing signal, while the interconnecting node has no signal. The four load gates are all on different IC's. Which instrument will best help isolate the problem?
A) Logic probe B) Logic analyzer C) Oscilloscope D) Current tracer
