Magnetron. Peak anode voltage/current, pulse input/output, frequency, VSWR, and thermal limits are retained in TUBE_SECTION_PARAMETER because conventional valve promoted fields do not map cleanly.

Source-dependent data

Operating conditions by source

Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
