If the T2-MI signal supply for the transmission site is also monitored, the error sources can be traced back to the gateway or transmitter (see Application Sheet “Testing and Monitoring the DVB-T2 Signal Feed via the new T2-MI interface “). Due to the high complexity of DVB-T2 signals with multi-PLP, a separate receiver is required to analyze each PLP.Application
The R & S®DVMS4 instrument can be equipped with up to four DVB-T2 receiver modules (R & S®DVMS-B54) to provide parallel, seamless monitoring of all PLPs present in a transmission channel. Operators can respond immediately to any errors or failures and reliably detect even sporadic short-term errors.
Individual PLPs can also be module, which is the most cost-effective solution and can also be realized with the more compact R & S®DVMS1 instrument. The R & S®Scheduler software supports configuration and control for sequential mode.
The operator can define the sequence and monitoring periods for any number of PLPs on the intuitive user interface. The results are displayed in tabular form. The results can be recorded and made available to network management systems via the instrument’s SNMP interface.
If a problem is detected in a PLP during the sequential analysis, the R & S®DVMS1 instrument can be configured to automatically extend the monitoring period to allow the source of the disturbance to be recorded. In sequential mode, the blind time for each PLP increases with the number of monitored PLPs.
Errors occurring during the blind time go unnoticed, as during this period another PLP is being analyzed or a switchover between two PLPs is in progress. This mode of operation slows the operator’s responsiveness in the event of an error and makes it more difficult to detect short-term errors. Furthermore, the signal quality is not fully documented.
Parallel and sequential monitoring can be combined to achieve an optimal compromise between error detection reliability and cost. For example, a dedicated receiver module can be used for continuous monitoring of the
PLP carrying the fundamental live broadcast, while each of two additional modules sequentially monitor two PLPs. This configuration requires only three receiver modules instead of five and still guarantees a reasonably short response time in the event of an error.
