Input interface module that enables monitoring of digital terrestrial transmissions. Two modules may be housed in a 1RU chassis together with a controlling VB120 or VB220 probe, providing high monitoring capacity occupying a minimum of rack space. In addition to monitoring typical RF parameters, the monitoring solution optionally allows advanced analysis of the complex DVB-T MI protocol; signal integrity is verified layer by layer. This analysis functionality is complemented by the renowned video bridge ETSI TR 101 290 monitoring engine to ensure standards conformance at all levels.
