CATV Experts
 
CX Family

VeEX™ CX series are next generation test solutions designed for analog and digital cable TV networks supporting VoIP, WiFi, and Internet service. Analog and Digital SLM, ingress noise sweep, deep interleave support, and QAM constellation analysis are among many standard features. Enhanced optional features include QAM16/64/128 Upstream Generation (USG), Reverse Path QAM Analysis, and DOCSIS 2.0/DOCSIS 3.0 Cable Modem emulation. A high capacity LiIon battery pack provides extended autonomy for a full day use with only a single charge.

The CX380 and CX380-D3 are super-tech installation and maintenance tools for next generation CATV networks. Equipped with a large 7" touch-screen color LCD and intuitive graphical user interface, the CX380 and CX380-D3 can be used under all light conditions. These highly flexible units combine a 1GHz spectrum analyzer with 60dB dynamic range, a forward and return path Digital QAM analyzer, and an MPEG analyzer in a single portable instrument.

An array of advanced digital measurements are available on both units, including MER, Pre/Post BER, EVM, HUM, Phase Jitter, Frequency Response, Equalizer taps, In-channel flatness, frequency and symbol rate errors, addressing all testing aspects of standard and high definition CATV signals. An intuitive statistic mode records up to 60 minutes of signal history displaying Level, MER, Pre/Post error rate, and errored seconds and other anomalies in minute or second resolution and intervals.

An optional dual band DOCSIS 2.0/3.0 cable modem verifies Internet connectivity and Triple Play services via the RF interface. Comprehensive return path analysis is possible when the built-in Upstream Signal Generator is connected to a CX380 or CX180R monitoring system located at the headend.

The new CX380-D3 integrates a certified DOCSIS 3.0 cable modem and an advanced spectrum analyzer; technicians can now identify ingress sources with greater dynamic range and perform comprehensive channel bonding.

At a weight of less than 2.5 kg/6 lb, the CX380 and CX380-D3 ensures portability, while the smart LiIon battery pack provides 8 hours of autonomy.
