Part 4/6:
After replacing the necessary components, the technician focused on restoring the oscillator, which is key for the oscilloscope's waveform generation and measurement accuracy. He mentions getting the storage control area of the device to start working and ensuring it comes out of a "holding" state. To do this, he reconnects the circuit, soldering the connections carefully, and prepares to reassemble the unit.
Once reassembled, he powers on the device for testing. He notes that his probe is hanging nearby and tests its activity by touching it, confirming that the device is now responsive. This step indicates successful calibration and functioning of the electronic circuits involved.
