Custom Uncertainty Calculator

This document provides technical specifications for the corrected performance of the PXI VNA using

either the N4691B Electronic Calibration Module, or the 85052D Standard Mechanical Calibration Kit.

To determine transmission and reflection uncertainty curves with other calibration kits, please download

our free Uncertainty Calculator from http://www.keysight.com/find/na_calculator to generate the

curves for your specific calibration kit.
