RF harmonic marker source

Earlier nonlinear diode harmonic generator driven by a time-referenced low-frequency source; only characterized harmonic markers can support commissioning.

Discovered · unresearchedClosure: OpenInventory incomplete

Capability requirements and tolerances

Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.

Parts and Tools needed

No researched inventory yet. This is an unexpanded frontier; an empty list does not mean the item can be obtained directly from nature.

What remains unresolved

Canonical reuse assessment
"Different architecture from instrument tunable LC source: integer frequency multiplication for reference marks; does not replace final RF stimulus or prove band coverage."
