Frequency Qualification (Optional)

The project breadboard has already demonstrated 20 MHz operation. See the 20 MHz oscilloscope measurement for the recorded clock evidence and capture procedure. Phases 9 and 10 use this 20 MHz configuration after SRAM loading and verification.

Additional frequency testing is optional. Complete the normal phase tests; use this check if you change the wiring, components, or clock configuration, or want measurements from your own board.

1. Run the Phase 6 SRAM screening or 20 MHz soak test appropriate to your setup.
2. Measure the clock using the oscilloscope guide.
3. Repeat the applicable Phase 9/10 boot, disk, and terminal checks. Record the measured frequency, firmware revision, and any errors.

A clock capture confirms frequency; functional tests confirm operation under the tested workload. If a check fails, resolve it before continuing.
