- Comprehensive suite of RF, modulation, and data quality measurements, based on recommendations for testing DVB-C systems
- Verify your quality of service
描述
All cable TV network operators planning the introduction of digital services have increasing competitive pressure to install these new services - quickly. Aggressive activation schedules require test equipment capable of verifying your quality of service - fast.
The Agilent 8594Q QAM (Quadrature Amplitude Modulation) analyzer is a comprehensive and powerful test solution, primarily designed for installation and maintenance test on European DVB-C systems.
Supporting 8, 4 and 2 MHz channel bandwidths, the 8594Q QAM analyzer makes both qualitative and quantitative measurements on the transmitted 64 QAM signal. It gives engineers the measurement capability required to accurately verify the quality of service delivered to subscribers.
Option J91 supports the 6 MHz channel bandwidth and symbol rates used on cable systems in North America and elsewhere.
The 8594Q QAM analyzer can help you during: headend equipment installation and maintenance, system verification, field installation and maintenance, and modulator manufacturing test.
The 8594Q QAM analyzer demodulates and accurately measures the QAM signals carried through the DVB-C system. It provides new measurement metrics necessary to characterize these signals and troubleshoot problems. The 8594Q QAM analyzer's graphical displays, clear user interface, and one-button measurement capability will make the transition from analog to digital testing easy for cable TV engineers.
Add option 195 to the 8594Q QAM analyzer to verify that the DVB-C MPEG data has been correctly decoded, and check transport stream content. The option also provides a real-time output (both ASI and parallel), to allow access to the data stream for further compressed MPEG analysis.
