2 With IF bandwidth of 10 Hz.
3 With impedance matched load.
4 High-level noise is the RMS of a continuous measurement of a short circuit or thru.
5 Arrived at by bending 11857D cables out perpendicular to front panel and reconnecting. Stability is much better with
less exing.
6 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 2 f (GHz)] 2 1
