Do the required minimum performance specifications in Technical Appendix 1 need to be tested on all RF channels (2 through 69 inclusive)?
The law requires converter boxes to contain features or functions necessary to “enable a consumer to convert any channel broadcast in the digital television service into a format that the consumer can display on television receivers designed to receive and display signals only in the analog television service.” Therefore, the intent of all of the specifications is that the requirements be met on every applicable TV channel. Manufacturers are expected to use engineering judgment in determining how many and which channels to test for each of the requirements so they are confident the requirements can be met on all channels. In exercising this judgment, it is recommended that manufacturers consider the following. (1) The manufacturer’s knowledge of its tuner design may provide a basis for identifying channels that are most likely to exhibit degraded performance. (2) FCC tests have demonstrated that some DTV tuners exhibit significantly poorer sensitivity on low VHF channels than on high V
