IP and QAM/8VSB Monitoring Probe

The VB12-RF is a highly portable RF/ASI/IP monitoring appliance for terrestrial and cable applications. With integrated RF, ASI and IP ports and built-in ETR101-290 analysis and alarming, RF measurements, OTT monitoring and SCTE35 logging, the VB12-RF provides today’s headend and field engineers with all the inputs and features needed for broadcast or IP analysis at any location in the transmission chain for cable, IPTV and terrestrial broadcast operations.
Designed for the rigors of real-world use, the VB12-RF is smaller and lighter than many comparable monitoring/troubleshooting solutions and requires no external equipment or power supply.
The VB12-RF interfaces are Gigabit Ethernet, ASI and QAM/8VSB RF inputs as well as a separate Gigabit Ethernet management interface for easy connection to either a laptop or the management network. There is also an SMA input for 1PPS timing reception as used in DVB T2MI scenarios.
RF specific parameters are measured and analyzed, and alarms are raised if measurements are not within user-specified limits. Measurements include MER, SNR, BER and signal level. A QAM/8VSB constellation diagram is displayed to visualize symbol integrity.
The VB12-RF incorporates many of the most advanced and patented technologies from the VideoBRIDGE End-to-End monitoring system. The product features an integrated web server and can easily be installed as part of a multi-probe system with a central server.
For on-site analysis, an engineer can use the VB12-RF’s interface to measure directly in the field or capture the input signal for later use in the lab. The product can be left in the field for continuous monitoring and can easily be controlled remotely with the VideoBRIDGE Controller.
