High-level noise is the RMS of a continuous measurement of a short circuit or thru.
6
Arrived at by bending 11857D cables out perpendicular to front panel and reconnecting. Stability is much better with less
exing.
7
Arrived at using 11857D cables and full 2-port calibration. Drift is much better without calbes and with 1-port calibration.
For this case, drift typically is [0.1 + 0.05
