Deviser QAM Signal Analyser CCT-DS2460Q

Normally Ships Same Day
Availability: Out of stock

The DS2460Q is a multi-functional instrument that supports digital QAM and analog signals in CATV networks. It is the ideal tool for initial network installations, service, and troubleshooting tasks.

The ruggedized design includes an outer chassis protector,while the icon-based GUI features programmable preset pass/fail limits. The easy-flowing menus are designed for increased efficiency and productivity for all levels of technicians.

Other features - including return path & forward spectrum scan, 12 favorite tilt frequencies, AC line voltage test, HUM and DC voltage measurements, combined with complete data logging and management software - make this unit a versatile tool for cable installations.

MER, Pre & Post BER measurements, and statistics features allow quick verification of loose connections, generally related to pixelated pictures or slow DS internet data flow. The digital measurement functions also help identify mismatches caused by open coaxial lines or impedance mismatch.

Up to 10x Stored Channel Plans

For technicians & contractors who work in multiple HFC networks, having a choice of different channel plans is a must. The DS2460Q can learn a selection of up to ten (10) different channel plans. When connected to an RF drop, the DS2460Q learns analog/digital channels and custom frequencies through the built-in automated channel plan learning tool - or downloads them via Deviser's Toolbox PC software. The user can select up to 12 channels in each of the 10 user-defined plans and assign them to a favorite/tilt channel plan.

QAM Analysis / Channel Measurements

The DS2460Q measures and analyzes channel power, MER, and Pre-Post BER, including constellation display. The unit is compatible with 16/32/64/128/256 QAM modulation, and in addition, provides power measurements for QPSK and COFDM digital carriers.

Auto Diagnostic User-Defined Limit Test

The auto test simplifies the technician's work by displaying pass/fail results. Limits can be set by the end user for Power Level, MER, PREBER, POST-BER, Spectrum Analysis, Tilt, and HUM measurements. With the simple Save function, the technician is no longer required to manually note results, allowing more installations or service calls to be performed in a day. In addition, measurements are saved instantly to ensure performance accountability for each location - and reduce the need to return to previously tested sites.

Full Spectrum Scans with Marker Feature

The DS2460Q can scan 160 channels, allowing users to quickly and efficently measure flatness and amplitude of the HFC network. Using markers, technicians can quickly identify mismatch-related anomalies caused by poor grounding or damaged transmission lines.

Spectrum Analysis / Measurements

The DS2460Q offers a spectrum analysis mode that allows viewing of the full spectrum up to 1.2 GHz. For troubleshooting reverse path challenges, the DS2460Q can be set up to display frequency spans from 5~110 MHz. Spectrum mode includes marker tools for improved measurement interpretation, while the max hold feature helps capture transient anomalies.

Voltage Measurement

The DS2460Q measures battery voltage, trunk, & distribution line voltage of the cable system, accurately identifying AC or DC anomalies. The smart power management system enables approximately 5 hours' continuous operation from battery when fully charged.
