The Viavi 1G DSP SWEEPLESS Trilithic Series Maintenance Meter with DOCSIS 3.1, Cable Modem & Forward Passive Sweepless Sweep, is designed for or maintenance technicians who need sweepless sweep capabilities. The meter conveniently combines CATV, DOCSIS 3.1 Cable Modem, Gigabit Ethernet, and Optical testing - thereby eliminating the need for multiple instruments and saving capital expenses at the same time.

Designed to meet maintenance technician challenges, the 1G DSP meter has powerful troubleshooting tools for experienced techs, yet simplifies decision making and streamlines standard processes and procedures for the more novice tech. This results in more efficient technicians, greater overall system health, and allows techs to continue using the same meter as they become more experienced.

The 1G DSP can achieve throughput testing speeds of up to a gigabit/sec using a dedicated Ethernet test port or the internal cable modem.

The 1G DSP can perform either roundtrip or one-way Key Parameter Index (KPI) measurements for full Ethernet service testing. With constant payload testing for Layer 2 through Layer 4, the 1G DSP is built for verification of both Ethernet Service Level Agreement (SLA) and Quality of Service (QoS) metrics.

The 1G DSP features a large, high resolution, ultra-bright, color touchscreen interface, simple pass/fail indicators, and powerful autotest apps to streamline troubleshooting and make the technician's job easier. Everything about this next-gen meter was built with the technician in mind-from remote control of the meter via a web browser, to the long battery life, quick charge time, and glow in the dark keypad for those dark, cramped spaces.

Cable Modem (CM) Sweep

The CM Sweep feature is a first of its kind, patent pending sweep that uses the cable modem built into the meter to perform in-band sweeps within your modem carriers.

This feature not only allows operators to balance the upstream, but also allows them to see the percentage of pre-qualizer effort and isolate problems between active components without causing any issues with upstream modem performance.

When this function is selected, the meter injects up to eight (8) upstream modem carriers to talk back to the CMTS and use the pre-equalized data for each of the upstream carriers to plot a frequency response of what your upstream sweep would look like with injected carriers.

Passive Forward Sweep

The Forward Passive Sweep feature is a stand-alone test that doesn't use injected carriers but instead passively uses the live carriers in the HFC distribution system to test and set the tilt and gain of distribution amplifiers without the need for any dedicated headend gear.
