Solid-state instrument candidate failed electrical-instruments -> waveform-reference-instrument -> electrical-instruments; removing only that row would retain ESD/solder-station calibration loops. Selected complete architecture changes to vacuum-device stages, CRT, independent primary scalar reference connections and manual heated joining, preserving source, conditioning, controls, display, protection and verification. Earlier galvanic source and thermionic/CRT manufacture are explicit unresolved physical frontiers. Software not required for this analog topology. Input bands, sweep/trigger fidelity, sensitivity, spectral response, rail demands and uncertainty remain unknown; no RF capability is silently claimed. Generic electrical-standard-cell is a comparison reference, not a load power source. Memory-first hypothesis; inventory and compatibility unreviewed.
Making outline
- Assemble the same thermionic waveform-source/CRT observation modules, divider/bias and manual gain/time/trigger controls using separately qualified cold clamped/riveted point-to-point interconnect with actual retained contact force, guarded source/loading and independent amplitude/time/impedance/thermal/insulation qualification
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Identified requirement; no researched making route or qualified output yet.
- Current memory-first method needs source and compatibility review.
