Datasheet

Overview

The VIAVI CX200 SiteXpert is a handheld communications service monitor for field and infrastructure testing of land mobile radio (LMR) systems. It brings features from VIAVI's larger radio test sets into a field-portable package.

As the LMR market moves from analog to digital, the CX200 provides frequency, power and modulation analysis for both analog and digital systems. Supported technologies include AM/FM/PM/SSB, P25 Phase 1 and Phase 2 (including Linear Simulcast Modulation), TETRA, DMR, DMR Repeater and NXDN, with OneViewer post-analysis software.

Digital Radio Analysis

With the P25 and DMR options, the large display presents modulation analysis tools such as distribution plots, eye diagrams, constellation plots, trajectory plots (P25) and burst profile plots (DMR). Several plots can be viewed at the same time or a single plot expanded to full screen. The TETRA option supports testing of TETRA radios, mobile stations and base stations.

Automated Testing

The optional Auto-Test applications provide automated testing and alignment of land mobile radios with minimal user input.

Cable and Antenna Analysis

A standard 1-port vector network analyzer supports Distance to Fault, VSWR and Return Loss measurements. Calibrated measurements require the Short-Open-Load calibrator.
