Instrument
LiteVNA64. Warmed up for 24 hours before measurement, so the instrument is at thermal equilibrium when sweeps begin.
Calibration
SOLT with quality standards, repeated 5 times at equal time increments over the 10-hour session to bound drift.
Sweep
12,276 points per DUT from 1 MHz to 8 GHz, with 5-trace averaging.
S11
Reflection measured with a precision 50 ohm load terminating the through port, to suppress false reflections from cable mismatches.
S21
Transmission via the VNA's direct through-measurement. No de-embedding, so the published number is what you would measure on your own bench.
Range note
LiteVNA64 is rated to 6.3 GHz. Treat content past that as reference only. With 5-trace averaging it is still useful, just noisier.
