DS2460Q QAM Analysis Meter

The QAM DS2460Q analyzer for analysis is a multifunctional instrument that works with digital QAM and analog signals in CATV networks. It is used to measure most parameters in digital TV (channel power, MER, BER, constellation diagram) and analog TV (single frequency level, full spectrum level of channels, noise). The device is great for initial network installation, service, and troubleshooting tasks.
The rugged design includes external enclosure protection, while the icon-based graphical user interface has programmable pre-set pass / fail boundaries. The easy-to-navigate menus are designed to increase the efficiency and productivity of technicians of all levels.

Other features - including return path scanning and forward scanning, 12 favorite frequency slopes, AC mains voltage test, noise and DC voltage measurements, combined with complete data logging and management software - make the DS2460Q a versatile tool in installations cable.
MER, Pre-Post BER, and statistics allow you to quickly verify loose connections, typically associated with pixel images or slow data flow over the DS Internet. Digital measurement functions also help identify mismatches caused by open concentric lines or impedance mismatch.

Device design

Storage of up to 20 channel plans
For technicians and contractors who work on multiple HFC networks, having a choice of different channel plans is a must. The DS2460Q offers up to twenty different channel plans. When connected to an RF drop, the DS2460Q learns analog / digital channels and custom frequencies using the built-in automatic channel plan learning tool - or downloads them using Deviser's Toolbox PC software. The user can select up to 12 channels in each of the 20 custom-defined plans and assign them to a favorite tilt / channel plan.


QAM analysis and channel measurement
DS2460Q measures and analyzes channel power, MER and Pre-Post BER and displays constellation. It is compatible with 16/32/64/128/256 QAM modulations, and also enables power measurements for QPSK and COFDM digital carriers.


Spectrum analysis and measurement
The DS2460Q offers three different spectrum analysis modes: normal, fast and return path. Rapid spectrum analysis allows the technician to view the 5-1220MHz frequency range, while normal spectrum analysis optimizes the amplitude accuracy at a slower sweep speed.
To troubleshoot data transfer problems, the device can display the 5-65 MHz frequency ranges, providing an additional tool to data transfer technicians. All modes have access to Marker and Max Hold functions, making it easy to capture and analyze transient anomalies.


Full spectrum scan with marker function
The S2460Q can scan 160 channels, allowing users to quickly and efficiently measure the flatness and amplitude of an HFC network. Using markers, technicians can quickly identify mismatch anomalies caused by poor grounding or damaged transmission lines.


Noise measurements
HUM measurement helps technicians identify and troubleshoot problems that may arise from damaged capacitors, faulty line splitters, or overloaded couplers (due to weather conditions or excessive current). Both 60 Hz and 120 Hz tests at 400 Hz LPF are performed.


Automatic diagnostic test with user-defined limits
The automatic test simplifies the work of the technician by displaying positive / negative results. End users can set limits for power level, MER, Pre-Post BER, spectrum analysis, tilt and HUM analysis.
Thanks to the simple save function, the technician no longer has to manually save the results. This saves him more time on installation and servicing, and increases the efficiency of his work. Measurement data is saved immediately. This ensures performance accountability for each location and minimizes the need to return to previously tested locations.


File management - test data storage
Multiple test data files can be saved and stored as analog or frequency carriers, QAM or digital frequency carriers, channel scans, tilt measurements, frequency spectrum and / or noise measurements. The results are saved in the File Directory with a time stamp. Records can be transferred to a PC via the Toolbox software for report generation, printing and analysis.


Voltage measurement
The DS2460Q measures the voltage of the battery, line and distribution network of a cable system, accurately identifying AC or DC anomalies. The intelligent energy management system allows for about 5 hours of continuous operation from the battery when fully charged.
