DISCONTINUED, Replaced by CX380s-D3.1

Now with 24x8 Channel Bonding


CATV Network Testing Simplified

The CX380s-D3 is a super-tech installation and maintenance tool for next generation CATV networks. Equipped with a large 7" touch-screen color LCD and intuitive graphical user interface, the CX380s-D3 can be used under all light conditions. This highly flexible unit combines 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, 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.

Comprehensive return path analysis is possible when the built-in Upstream Signal Generator is connected to a CX380s-D3 or CX180R monitoring system located at the headend.

The new CX380s-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 CX380s-D3 ensures portability, while the smart LiIon battery pack provides 8 hours of autonomy.
