Our experts will answer any technical questionCIU-003 DVB-C and DVB-T signal analyzer is designed for measurement of TV channel parameters and transmission of measurement results to a remote PC using TCP/IP local area network. The Analyzer allows measuring signal level, V/A ratio and C/N ratio within the video channel bandwidth for the analog channels, and actual channel power level for digital channels. For DVB-C and DVB-T TV signals, the Analyzer offers the measurement of reception quality parameters: modulation error ratio MER, bit error ratio BER before and after Reed-Solomon decoder. The MPEG transport stream of DVB-C and DVB-T channels is checked for compliance to ETSI TR101290 requirements. The Analyzer is controlled by a remote PC via Ethernet interface.
Monitoring systems:
- Operating ViewRSA monitoring system:
- Measurement results reading and saving to data base
- Real-time display of measurement process
- Automatic measurement results checking against user-defined limit plans
- Error notification system: visual, sound alarm, e-mailing, executing user-defined applications
- Viewing measurement results history in tables and graphs
- Built-in WEB-browser for remote access to program
- Operating monitoring systems via SNMPv1 protocol:
- Measurement process control (start, stop, measurement interval setting)
- Sending traps with information on channel errors
- Traps can be sent to several SNMP-agents
- Real-time display of measurement results
