Measurement Port Characteristics
Measurement Uncertainty
Measurement uncertainty curves utilize an RSS (Root Sum Square) model
for the contribution of random errors such as noise and typical connector
and test set switch repeatabilities. These are combined with a worst- case
model for the contributions of dynamic accuracy and residual systemic
errors.
Curves show the worst- case magnitude and phase uncertainty for
reflection and transmission measurements, using the specified cal kit, with
10 Hz IF bandwidth, and no averaging during the measurement.
