Note : 1. * means the limit decreasing linearly with the logarithm of the frequency in the range
0.15MHz to 0.5MHz
2. If the limit for the measurement with the average detector is met when using a receiver
with a quasi-peak detector, the equipment under test shall be deemed to meet both limits
and the measurement using the receiver with an average detector need not be carried out.
