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

“How Keysight Verifies the Devices in Your Kit” on page 5-2
