HAR §16-131-40. General

The following performance standards shall be adhered to by all cable systems: (1) The frequency of the visual carrier shall be maintained at 1.25 MHz + 25 KHz above the lower boundary of the cable television channel, except that, in those systems that supply subscribers with a converter in order to facilitate delivery of cable television channels, the frequency of the visual carrier at the output of each converter shall be maintained at 1.25 MHz + 250 KHz above the lower frequency boundary of the cable television channel; (2) The frequency of the aural carrier shall be 4.5 MHz + 1 KHz above the frequency of the visual carrier; (3) The visual signal level at the picture frequency for each desired television channel shall be at least 0 dBmv (1,000 microvolts referred to 75 ohms), except when overload occurs at which time attenuation may be used to provide acceptable picture quality, and shall be maintained within: (A) 3 dB of the visual signal on either adjacent cable television channel (except for secured channels); and (B) 10 dB of the visual signal level on any other cable television channel (except for secured channels); (4) The voltage of the aural signal shall be maintained between 14 and 18 dB below its associated visual signal level; 131-17 §16-131-40 (5) The peak-to-peak variation in visual signal level caused by undesired low frequency disturbances (hum or repetitive transients) generated within the system, or by inadequate low frequency response, shall not exceed five per cent of the visual signal level; (6) The frequency response for any single channel shall be within a range of + 2 dB (except for secured channels); (7) The ratio of visual signal level to system noise shall not be less than 40 dB; (8) The cross modulation ratio on any channel shall not be less than +46 dB nor shall there be any visible cross modulation products produced on any channel carried by the cable system; (9) The terminal isolation between 50 MHz and 300 MHz provided for each subscriber shall not be less than 25 dB except that the isolation between separate television and FM broadcast terminals for the same subscriber shall not be less than 15 dB. In the case of multiple sets operating from a single drop, the isolation factor shall be 18 dB; (10) The spurious electromagnetic radiation shall fall within the limits prescribed by the Federal Communications Commission in 47 C.F.R. section 76.605(11) (1989) which is made a part of this chapter; (11) The system shall be designed for continuous operation; (12) The system shall be designed to operate within performance standards though the supply voltage may range from 105 to 130 volts; (13) The system shall be designed to transmit National Television Systems Committee monochrome and color signals over the system operating frequencies; and (14) The system shall be designed to have system level maintenance in both headend equipment and in main trunk or trunks.
