2003MAY27_RFT_AN01BROADCASTING DIVISIONAPPLICATION NOTERF Level Measurement Accuracy of DTV Test ReceiversProducts:TV Test Receivers, DVB-C DVB-TEFA7BM12_0ERF Level Measurement Accuracy of DTV Test ReceiversOne of the most important parameters for determining the transmission quality in an RF channel is the receive level. In analog TV, the peak level of the sync base line is measured for this purpose. As a precondition, the resolution bandwidth must be sufficiently wide to allow all filters to settle during the 4.7-s base line period. The resolution bandwidth should be at least 1 MHz. The power distribution in the transmission channel is of no importance here. In any case, there will be maximum and constant power in the region of the sync base line. Nominal amplitudes are as follows: 300 mV, ……
