Network-Information-Table (NIT)
The NIT (Network Information Table) is a special table containing information about other
transponders/channels within the network (e.g. satellite, cable, DVB-T network). Information from
the NIT can be used for navigation purposes (program search).
The measuring receiver must first receive a digital channel. NIT search is started by pressing
MODE
