VeEX VePAL CX380S-D3 CATV Tester

Designed for analog and digital cable TV networks with enhanced spectrum anaylsis, digital channel, DOCSIS, Sweep, MPEG analysis and Ethernet test capabilities

Super-Tech Maintenance Tool for CATV  VeEX CX380S-D3 DOCSIS 3

Now with 24x8 Channel Bonding

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.

Upstream Signal Generator (USG)

Evaluate the bandwidth and noise performance characteristics of the reverse path with a choice of CW, QPSK, 16 QAM, 64 QAM and 128 QAM modulation types using industry standard symbol rates. Transmitting a known reference signal between 5-65 MHz (Annex A) or 5-42 MHz (Annex B) into the reverse path at a user defined power level and modulation, allows a technician to evaluate phase and amplitude distortions resulting from any misalignment present in the network. Injected reference signals can be used to determine the headroom in the reverse path and to identify laser clipping resulting from signal overload.

Return Path Sweep

The CX380S-D3 incorporates a sweep transmitter (USG) capable of generating sweep tones over a 5 MHz to 65 MHz frequency range with 125 kHz resolution, and amplitude levels ranging from 0 to 58 dBmV with 1 dB resolution. When paired with a companion CX380 Series handheld unit or a CX180R RPM System located in the Headend, the entire return path frequency spectrum can be precisely characterized for DOCSIS 3.0 communications. Protection “Guard Bands” can be pre-configured to prevent test tones interfering with active DOCSIS transmissions. The sweep system communicates the user defined sweep tables and measured test data over the Internet, freeing up valuable downstream bandwidth typically used by conventional telemetry systems found in competitor systems.

Testing Premise

From the Customer Premise, test directly at the RF interface or through the real Cable Modem’s Ethernet interface. At the CATV Headend office, connect a MPX100 or any other VeEX Ethernet test set behind the CMTS. Here the MPX functions as a Responder, with only an IP address needed to be configured on the test port. The CX380S-D3 functions as the Controller via the RF or Ethernet interface, running the RFC2544 Asymmetric test suite.
