Table 2-4 through Table 2-6 list the electrical specifications of the terminations, ¼
wavelength shims, and standard sections in your kit.
Measurement Uncertainty
Vector Network Analyzer (VNA) measurement accuracy depends on the accuracy of the
calibration standards, the calibration method employed, instrumentation accuracy and
stability, environmental factors, and the actual characteristic of the device under test
(DUT). Because of the complexity in these relationships, Agilent created uncertainty
computation tools to calculate the overall measurement uncertainty of a VNA system. In
the past, when the Agilent 8510 VNA system was being produced, a “Specification and
Verification” RMB program was included to perform an uncertainty calculation. Currently,
for the Agilent PNA and ENA families of network analyzers, a customer can download the
