If I turn off the circuit board and I print out the datasheets for every logic chips and analog IC chip and use an external power supply to apply directly to the power pins ( +VCC and ground pin of an IC chip ) to tests its inputs and output. Stepping through troubleshooting each IC chip one at a time with the circuit boards power supply off and nothing else turned on. I'm just stepping through each IC chip one at a time applying voltage to the VCC and ground using an external power supply and then using a logic pulser or function generator to test the inputs and using an oscilloscope to monitor the outputs of the chip. Can this be done?
The Board is turned off and I'm not using the circuit boards power supply. I'm using an external power supply to apply directly to the IC chip that I want to test, check, verify and troubleshoot. I will tests its inputs using a logic pulser or function generator and monitor the output pins using an oscilloscope. Troubleshooting each IC like this one by one. Can this be done?
