SECTION 1: GENERAL, SUPPLEMENTARY DEFINITIONS AND CONDITIONS
OF MEASUREMENT
5.4 Limitation of the measuring audio-frequency band
Replace, on page 11, this subclause by the following:
Because some properties, for example noise and audio-frequency harmonic distortion, depend
upon the audio-frequency bandwidth of the test equipment, reproducible results can be
obtained only when the band of audio-frequencies occupied by the demodulated signal is
restricted to specified limits.
This restriction may be accomplished by means of a band-limiting filter preceding any audio-
frequency measuring device and adapted to the type of signals to be transmitted. The filter may
be incorporated within the measuring equipment. When measuring residual hum and noise,
only the low-pass portion of the filter need be specified (see appendix A).
Page 13
SECTION 2: METHODS OF MEASUREMENT
8.3.2 Method of measurement at the antenna terminals
Add, on page 15, the following sentence to 8.3.2 a):
If the band rejection filter exhibits unwanted attenuation (certain types of band rejection filters,
such as those constructed with transmission lines or cavities, can have unwanted attenuation
at odd multiples of the centre frequency of the rejection bandwidth), for the measurement of
spurious components at and above the second harmonic of the carrier frequency, the band
rejection filter shall be replaced by a high-pass filter whose cut-off frequency is approximately
1,5 times the carrier frequency.

8.4.3 Method of measurement
Add, at the end of 8.4.3 e), the following note:
NOTE – The permissible input level which does not degrade the receiver performance can be calculated from
P = P – A
≤ P + S – 10 dBm
rt t
r
where
P is the permissible receiver input level, in decibels (dBm);
rt
P is the carrier power of transmitter under test, in decibels per metre (dBm);
t
A is the attenuation recorded in step e), in decibels (dB);
P is the reference sensitivity of the test receiver, in decibels per metre (dBm);
r
S is the selectivity of the receiver, in decibels (dB).
