This document provides technical specifications for the M9485A PXIe multiport vector network analyzer. The configuration is shown below

Calibration Kits and ECal Modules

This M9485A data sheet also provides technical specifications for the following calibration kits and ECal modules. For models not listed in this data sheet, please download the free Uncertainty Calculator from http://www.keysight.com/find/na_calculator to generate the curves for your calibration kit and enable VNA setup.

Definitions

Specification (spec.):

Warranted performance. All specifications apply at 25 ºC (± 5 ºC), unless otherwise stated, and 45 minutes after the instrument has been turned on. Specifications include guard bands to account for the expected statistical performance distribution, measurement uncertainties, and changes in performance due to environmental conditions.

Typical (typ.):

Expected performance of an average unit which does not include guardbands.

General characteristics:

A general, descriptive term that does not imply a level of performance.

Boundary Conditions

If the same boundary conditions fall under more than one category in a table, apply the best value. For example, system dynamic range in page 4 is 139 dB with the following boundary conditions.

Frequency: 20 MHz

IF bandwidth: 10 Hz
