  • 4 Port cPCI Card

    GX3904 - Terotest Systems Ltd.

    The GX3904 is an 8-port, cPCI asynchronous communications interface board supporting (4) RS232 and (4) RS422 signal levels. The four RS232 ports offer a full set of data and modem control lines configured for DTE operation. The four RS422 ports offer differential signaling and support DTE operation. Each RS422 differential pair is terminated by a 150 Ω parallel resistor. An optional transition cable is available to convert the front panel SCSI connector to (8) DB-9, D-sub connectors.

  • Remote Spectrum

    ZCorum

    Remote Spectrum is a downstream spectrum analyzer app that lets you view the spectrum passing through a customer’s cable modem or set-top box right on your PC, laptop, tablet or smartphone from anywhere in the world. It’s like having a spectrum analyzer right at the customer’s location that you can instantly connect to whenever you like, wherever you are. There is no need to connect a meter, no expensive probes in your network, and no need to roll a truck into the field in a trial and error search for the problem. With Remote Spectrum you will lower your equipment and operational costs and reduce your mean-time-to-repair.

  • Digital TV Spectrum Analyzer

    DS2831 - Deviser Instruments

    Fast Spectrum Analyzer: detect and troubleshoot ingress with exceptional sensitivity of -60dBmV @ 300KHz RBW. Color-Coded Persistence Test: find transient noise hiding under upstream bursty signaling, without disrupting service. MER Measurement: up to 47 dB MER with 48 hours of statistical recording with 1 second resolution. Analog TV and SC-QAM: troubleshoot typical analog interference and distortions as well as SC-QAM performance. Time-Domain EVS Measurements: uncover interference from LTE signals under downstream QAM carriers with no service interruptions.Characterize OFDM carrier performance and DOCSIS 3.1 cable modem performance.

  • Proactive Downstream Spectrum Analysis

    SpectraVizion - ZCorum

    SpectraVizion is an innovative, software-based diagnostics tool that leverages new advancements in remote spectrum capture, allowing cable operators to address downstream spectrum impairments proactively, before subscribers call in with service complaints. “Troubleshooting downstream spectrum issues has always been a reactive process for cable operators,” said Arthur Skinner, Vice President of Worldwide Sales for ZCorum. “Often they’re not aware they have an issue until a customer calls, and that’s when they then send a technician to the home with a hand-held meter to start a search for the problem.” SpectraVizion takes the guesswork out of problem identification and location by presenting on a simple dashboard a list of devices that are experiencing common downstream issues like Standing Waves, FM Noise, Suck-outs, Roll-off and Tilt. The tool leverages the spectrum data available from cable modems and set-top boxes that support full band capture, and advanced detection algorithms automatically identify devices experiencing downstream impairments. The operator can click on any device in the list to view a capture of the full spectrum from that day, or up to 30 days in the past.

  • Broadband Diagnostics

    TruVizion - ZCorum

    TruVizion gives you a comprehensive view into the health of your cable or DSL network, including up to 90 days of historical data.PreEqualization Analyzer lets you quickly find upstream impairments like reverse splitters, loose or corroded connectors and bad wiring. Plus, you can be proactive and actually fix those problems before they affect service for your subscribers.RF Inspector is an inexpensive app that can do what a meter can do, except it can do it on a tablet from wherever you happen to have Internet access. That means in the office, at home, or in the field.Upstream Analyzer shows you the RF signals for all ports and modems on your Cisco CMTS without any additional equipment, cabling or connectors, and yes, you can see ingress under the carrier with one click.

  • Serial Board

    104-COM232-8 Series - Acces I/O Products, Inc.

    This is an eight, four, or two-port, asynchronous, serial communication board designed for use on the PC/104 bus. It supports full RS-232 serial communications. The board may be installed in any standard PC/104 stack. Connections are made via two 40 pin IDC type right angle connectors for the boards optional breakout cable. The boards are feature-rich and allow for the connection of multiple serial devices—ideal for a variety of applications such as POS, barcode readers, modems, machine monitoring and control, military, high-density networking applications or any other application requiring the connection of RS-232 serial devices to a PC/104 compatible system. Type 16780 UARTS are used as the asynchronous communication elements. These include 64-byte transmit/receive FIFO buffers to protect against lost data in multitasking systems while maintaining 100% compatibility with all operating system COM port drivers. ACCES offers the 104-COM232-8 series in both standard and extended temperature versions ideal for outdoor applications or harsh industrial surroundings. Ordering options include UARTs with larger FIFOs, support for custom baud rates, vertical I/O pins, and custom cabling.
