DVProbe-S2 Features Contribution Monitoring for Satellite Network

The tug of war between efficiency and complexity is not new. With the prevalence of DVB-S2, satellite operators embrace the ability to utilize their transponders more efficiently, but they wince at the increased complexity of monitoring transmission. Coming to their rescue, Pixelmetrix presents DVProbe-S2, a compact yet powerful solution for monitoring digital satellite transmission. As a future-proof satellite downlink monitoring solution, the DVProbe-S2 decodes advanced modulation formats in DVB-S/S2 networks and performs in-depth transport stream analysis and monitoring. Moreover, it supports DVB-S2, DVB-DSNG and DVB-S modulations as well as H.264 SD/HD services. One key feature is remote downlink monitoring. The DVProbe-S2 offers visibility into contribution links at remote downlink centers, with comprehensive RF integrity and in-depth TS analysis checks. It also provides signal integrity measurements of individual transponders on the L-Band feed in parallel with TS monitoring. Satellite truck monitoring is another vital feature, enabling DVProbe-S2 to seek and monitor ad-hoc connections effectively, verifying RF and TS integrity. DVProbe-S2 provides continuous, real time measurement, SNR and MER symbol rate offset and center frequency offset measurements are available. Other checks performed include bit error ratio measurement, carrier level measurements and detection of short duration losses of FEC lock.
Key Features At a Glance: - Both pilot and no pilot mode - Modulation fidelity analysis via SNR and MER - Constellation visualization - Long-term logging of all measurements - Multiple configuration profiles and round-robin scheduler for monitoring multiple transponders
In order to simplify and clarify issues for broadcast engineers, visualization is indispensable. A high-resolution graphical display of the constellation scatter plot enables the engineer to classify noise impairments such as Gaussian and phase noise. Multi-user remote access, over LAN, internet or modem connection, is also available. Even if you are out for a lunch break, leave it to the DVStation Alarm Sub-System to trigger actions on errors such as log entries, audible alarms, SNMP traps, contact closures, transport stream recording and user-programmable actions. Satellite operators echo the need to measure signal integrity – DVProbe-S2 responds. With remote downlink and satellite truck monitoring, DVProbe-S2 helps operators ease the transition to DVB-S2 by effectively performing RF and TS integrity checks.
