INTRODUCTION
Clause
1. Object
2. Scope
SECTION ONE - GENERAL TERMS RELATING TO WANTED MODULATION
3. General notes on modulation
4. Amplitude modulated emissions
5. Angle-modulated emissions
6. Pulse-modulated emissions
SECTION TWO - MEASUREMENTS RELATING TO WANTED MODULATION
7. Modulation factor of amplitude-modulated emissions
with full carrier
8. Utilization factor of amplitude-modulated emissions
9. Frequency (or phase) deviation, frequency shift and
centre-frequency variation of angle-modulated emissions
10. Utilization factor of angle-modulated emissions
11. Utilization factor or modulation factor of pulse-modulated
emissions
SECTION THREE - CHARACTERISTICS OF TRANSMITTERS RELATING
TO WANTED MODULATION
12. Input voltage for rated modulation, modulation input ratio
and utilization factor/input voltage characteristic
13. Maximum long-term utilization (or modulation) factor and
maximum short-term modulation input ratio
SECTION FOUR - VARIATION IN THE CARRIER CAUSED BY MODULATION
14. General notes on carrier-amplitude variation
15. Carrier-amplitude variation in transmitters for
radiotelephony or sound broadcasting with full carrier
16. Carrier-amplitude variation in radiotelephony
transmitters with reduced carrier
SECTION FIVE - UNWANTED MODULATION, INCLUDING HUM AND
NOISE MODULATION
(Under consideration)
Describes the conditions and methods of measurement for assessing the performance of transmitters with respect to wanted and unwanted modulation. The methods of measurement described are restricted to those properties that may be liable to ambiguous interpretation due to the application of different methods and conditions of measurement and are intended for type tests and acceptance tests but may also be used for factory tests.
