(c) For any transmitter the maximum level of
any harmonic generated shall be at least 60dB
below the peak envelope power, developed with
the vision transmitter operating at full power
and the sound transmitter operating at maximum
deviation, and shall not exceed a power of
25 microvolts.
(a)
Sub-harmonic and combination frequencies
generated within the transmitting equipment
shall not have amplitudes greater than 1
microwatt.
(e) When any transmitter is operated at full
power into an adequately screened test band,
the field strength at a distance of one metre
shall not exceed 100 mV/m.
(f) The level of RF power present in the
power lines or control cables to a transmitter
shall be maintained below the minimum liable
to cause any disturbing influence to other
equipment in the transmitter station.
