An output gate is connected to four input gates; the circuit does not function. Preliminary tests with the DMM indicate that the 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 ICs. Which instrument will best help isolate the problem?

If the pulsating signal is applied to the first gate, it means a. C current is applied. IC's won't work with AC power. How current tracer works? I didn't understand the question. Can anyone explain?

We have input at the primary gate but didn't get any output it means the current level is quite low. So we have to check it.
