M983xA Series PXIe Vector Network Analyzer

Introduction

Characterizing sub-systems such as transmit/receive (T/R), or multiport front-end modules (FEM) is not easy. Requiring beyond just the standard S-parameter and noise figure measurements, these modules additionally need you to do high sensitivity and high-power performance characterization, as well as modulated signal tests such as EVM and ACPR. Juggling a network analyzer, signal analyzer, and a switch matrix not only takes up valuable time, but also introduces even more measurement complexity.

The M983xA PXIe vector network analyzer (VNA) combines all your measurements into a single instrument, enabling system characterization with faster speeds and greater flexibility, at a lower cost. The PXI’s form factor scalability, built-in noise receivers, and configurable test set combined with modulated signal measurements allow you to characterize highly integrated components with a single connection. Easily perform RF measurements with software wizards to guide you through advanced wideband measurements.

Definition

Specification (spec)

Warranted performance. Specifications include guardbands to account for the expected statistical performance distribution, measurement uncertainties, and changes in performance due to environmental conditions. All specifications and characteristics apply over a 25 °C ± 5 °C and relative humidity of 25 to 70% range (unless otherwise stated).

The following conditions must be met:

• Module temperature is between 40 to 53 °C.

• Instrument has been turned on for 90 minutes with VNA application running.

• Instrument is within its calibration cycle.

• Instrument remains at a stable surrounding environment temperature (between -10 °C to 55 °C) for 60 minutes prior to turn-on.

Characteristics (char.)

A performance parameter that the product is expected to meet before it leaves the factory, but that is not verified in the field and is not covered by the product warranty. A characteristic includes the same guardbands as a specification.

Typical (typ.)

Expected performance of an average unit at a stable temperature between 25 °C ± 5 °C for 60 minutes prior to turn-on and during operation; does not include guardbands. It is not covered by the product warranty. The instrument must be within its calibration cycle.

Nominal (nom.)

A general, descriptive term or design parameter. It is not tested, and not covered by the product warranty.

Supplemental Information

A performance parameter that is tested on sampled product during design validation. It does not include guardbands and is not covered by the product warranty.

Calibration

The process of measuring known standards to characterize an instrument's systematic (repeatable) errors.

Corrected (residual)

Indicates performance after error correction (calibration). It is determined by the quality of calibration standards and how well "known" they are, plus system repeatability, stability, and noise.

Uncorrected (raw)

Indicates instrument performance without error correction. The uncorrected performance affects the stability of a calibration.
