1 A ccuracy enhancement procedures are performed using 85036B 75 type-N calibration kit. Enviromental
temperature is 23 C 63 C at calibration: 61 C from calibration temperature must be maintained for valied
measurement calibration.
2 With IF bandwidth of 10 Hz.
3 High-level noise is the RMS of a continuous measurement of a short circuit or thru.
4 Arrived at by bending 11857D cables out perpendicular to front panel and reconnecting. Stability is much better
with less exing.
5 Arrived at using 11857D cables and full 2-port calibration. Drift is much better without calbes and with 1-port
calibration. F or this case , drift typically is [0.1 + 0.05 2f (GHz)] 2 1 C, degrees .
