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, Keysight created uncertainty computation tools to
calculate the overall measurement uncertainty of a VNA system. In the past,
when the Keysight 8510 VNA system was being produced, a “Specification and
Verification” RMB program was included to perform an uncertainty calculation.
Currently, for the Keysight PNA and ENA families of network analyzers, a
customer can download the VNA Uncertainty Calculator program. (To access
this program from the Web, navigate to www.keysight.com and enter
“calculator” in the Search function.) Explanations of the uncertainty model are
provided in the PNA embedded Help files. Additional references on VNA
measurements are available from the Keysight Applications Notes and
Technical Papers Web page, accessed from www.keysight.com by clicking on
the Application Notes and Technical Papers hyperlink.
Certification
Keysight Technologies certifies that this product met its published
specifications at the time of shipment from the factory. Keysight further
certifies that its calibration measurements are traceable to the United States
National Institute of Standards and Technology (NIST) to the extent allowed by
the institute’s calibration facility, and to the calibration facilities of other
International Standards Organization members. See
the Devices in Your Kit” on page 1
