Key facts
Individual evaluation of the actual measurement uncertainty
Verification kits help to evauate the actual measurement uncertainty under given test conditions. The uncertainty information in the data sheet is limited by nature, in practice much more parameters will contribute to measurement uncertainty. This the actual test performance can only be evaluated by verifying the actual test setup. The ZNA-K50(P) option provides software support. All characterization data is traceable to the Swiss Metrology Institute METAS. An R&S®ZNA verification requires the following:
Covering a wide impedance range for high reliability
The R&S®ZVA-Z4xx verification kits include attenuators, mismatch, offset short and a stepped line. In combination with the stepped line standard, impedance limits (very high/low reflection) and a wide swath of the middle impedance range can be checked. As a result, uncertainty is proven in a matching range where most DUTs can be found.
Reliability without a line standard
Line standards are typically used for VNA verification. However, the loose inner conductor of an air line is mechanically difficult to handle and may not be centered exactly in the connector reference plane. To ensure reliable results, the R&S®ZV-Z4xx includes a stepped through instead of an air line.
Traceability of characterization data
The characterization data (S-parameters) plus the corresponding uncertainty data (provided with an accredited calibration) can be traced to the globally renowned Swiss Federal Institute of Metrology METAS, ensuring the highest possible level of certainty.
