Supplemental Performance Characteristics
This section provides useful data on the 16197A. These supplemental
performance characteristics should not be considered specifications.
Additional Error
Additional errors are calculated as follows.
|Z| Measurement
Additional error for Impedance Ze [%] is calculated by substituting the values
in the table below into the following equation.
Ze [%] = ± {A + (Zs/Zx + Yo ×Zx) × 100}
where
A [%] Test Fixture’s Proportional Error [%]
Yo [S] Test Fixture’s Open Repeatability [S]
Zs [

] Test Fixture’s Short Repeatability [

]
Zx [

] Measured Impedance Value of DUT [

]
where f is frequency (GHz)
D Measurement
Additional error for Dissipation Factor De is calculated by using the additional error for
Impedance Ze [%] as follows.
If Dx

0.1:
De = Ze / 100
If 0.1 < Dx  0.5:
De = (Ze / 100) × (1 + Dx)
where Dx is the measured value of D. It is necessary for Ze to be below 10%.
