Non-linearity in the ISDB-T transmission chain causes intermodulation products that widens the spectrum emission and should be taken into account when assigning frequency channels. The characterization of the transmission spectrum mask is one of the most important measurements in order to achieve the best use of the electromagnetic spectrum. The use of critical mask defined in [1] allows allocations of co-site adjacent channels for an efficient use of the electromagnetic spectrum that is a finite and limited resource. This paper discusses different test procedures using spectrum analyzers and dedicated digital TV analyzers in order to measure the ISDB-T transmission mask.
