Overview

The DS2460Q is a 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 r edized 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 the DS2460Q 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 20 Stored Channel Plans

For technicians and 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 twenty (20) 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 20 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. It is compatible with 16/32/64/128/256 QAM modulation, and can also provide power measurements for QPSK and COFDM digital carriers.

Spectrum Analysis & Measurements

The DS2460Q offers three distinct spectrum analysis modes:normal, fast, and return path. Fast spectrum analysis allows technicians to view a frequency range of 5~1220MHz; while normal spectrum analysis optimizes amplitude accuracy at a lower sweep speed. For troubleshooting upstream problems, the unit can display frequency spans of 5~65 MHz, providing an additional tool to technicians dealing with upstream data signals. All modes have access to the Marker and Max Hold

features, making it easy to capture and analyze transient anomalies.

Full Spectrum Scans & Marker Feature

The DS2460Q can scan 160 channels, allowing users to quickly and efficiently 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.

HUM Measurement

The HUM measurement helps technicians identify and troubleshoot anomalies that may result from defective capacitors, faulty line splitters, or overloaded couplers (caused by weather conditions or excessive current). Both 60 & 120 Hz tests are performed @400Hz LPF measurements.

Auto Diagnostic User-defined Limit Test

The auto test simplifies the technician's work by displaying pass/fail results. End users can set limits on Power Level, MER, Pre-Post BER, Spectrum Analysis, Tilt, and HUM measurements. With the simple Save function, the technician no longer must manually record results, saving more time for installations and service calls in a day. In addition, measurement data is saved instantly to ensure performance accountability for each location - and to reduce the need to return to previously tested sites.

File Management - Test Data Storage

Multiple test data files can be saved and stored as analog carriers or frequencies, QAM carriers or digital frequencies, channel scan, tilt, frequency spectrum measurements, and/ or HUM. Results are saved to the File Directory by timestamp. Records can be uploaded to a PC via the Toolbox software

for report generation, printing, and analysis.

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 on a full charge.
