R&S^®DVMS Digital TV Monitoring System Family

The new R&S®DVMS-B40 IP option for the R&S®DVMS monitoring family helps network operators achieve maximum operational reliability when feeding transport streams over IP networks. This option is used in the R&S®DVMS, the most compact monitoring system on the market today. Depending on the model, up to four signals can be measured simultaneously in a compact, one HU unit. The entire R&S®DVMS family comes with an easy-to-use user interface.

In digital TV networks, IP is used more and more to feed transmitter sites. Rohde & Schwarz has developed the R&S®DVMS-B40 option to provide comprehensive monitoring and detailed analysis of these IP signals. This option monitors all relevant quality parameters in the IP transmission. It performs a detailed check of up to four transport streams simultaneously. If one of the transmitted transport streams is faulty, the new option can extract this stream and transmit it to the central monitoring station, also over IP. The personnel at the central monitoring station can analyze the faulty transport stream in detail. Graphically presented results make troubleshooting easier. The network operator is able to immediately respond to signal failures or faults.

There are two models in the R&S®DVMS family. The R&S®DVMS4 (one HU) can monitor the transmitted RF signals from up to four transmitters at a transmitter site. RF modules are available for DVB-T, DVB-S, DVB-S2 and DVB-T2. The R&S®DVMS1 is ideal for transmitter sites where only one RF or transport stream signal needs to be monitored. This one HU, 1/2 19" unit can accommodate one of the above modules. The R&S®DVMS family is extremely flexible and can easily be scaled to meet users’ specific requirements, while offering an excellent price/performance ratio.

The R&S®DVMS-B40 option allows connection to up to 1 Gbyte electrical Ethernet networks. Optical IPs can also be connected to the R&S DVMS using small form-factor pluggable (SFP) modules. Using the simple network management protocol (SNMP), the R&S®DVMS can also easily be integrated into central management systems.

The R&S®DVMS is a comprehensive monitoring solution that enables network operators to detect all relevant faults at the RF, IP and transport stream level. Thanks to the flexible hardware concept, the R&S®DVMS can also be used for monitoring tasks in DVB-T2 networks.
