Advanced modulation techniques allow you to aggregate several independent transport streams into one single RF carrier. Selecting a specific transport stream is easy with your field strength meter RANGER Neo using the ISI Filtering function. This feature is available for DVB-S2, T2 and C2.
As part of the GSE (Generic Stream Encapsulation) protocol adopted in DVB-S2, DVB-C2 and DVB-T2 standards it is possible to aggregate independent transport streams into one single radiofrequency carrier that is commonly referred to as multistream. Each individual transport stream is identified by its ISI (Input Stream Identifier) and can be recovered transparently on the receiver side.
It is now possible to measure and decode multistream channels with field strength meter RANGER Neo. In order to do so the ISI FILTERING must be enabled under the signal parameters menu of the analyser as shown on the picture below.
We can then enter a specific stream identifier that will be used by the field strength meter to recover the corresponding transport stream, service list and programmes data.
