Because modulator rise times differ, triggers to each amplifier stage must usually be separately adjusted to provide proper synchronisation without excessive wasted beam energy... However, timing is not a problem with fully self-pulsing CFAs and is of concern only at the trailing edge of the pulse with dc-operated control-electrode CFAs. 2, record 1, English, - timing

Le synchronisateur est le cœur du système radar. Il délivre les signaux de base qui définissent les instants d'émission, et divers signaux annexes nécessaires à des opérations en temps réel. Son élément de base est une horloge de très grande stabilité [...] à partir de laquelle sont engendrés les signaux de synchronisation. Ces signaux sont distribués aux différents éléments à piloter. 3, record 1, French, - synchronisation

Low-power modulation. In an AM transmitter modulation of an RF stage prior to the final high-power stage. This system has the advantage that the modulator need only be of low power but the stage following the modulated amplifier must be linear to avoid distortion of the modulation envelope. 3, record 2, English, - low%2Dpower%20modulation

High-power modulation. In an AM transmitter amplitude modulation of the carrier by introducing the modulating signal into the anode circuit of the final amplifying stage. The power of the modulating signal thus approximates to that at the transmitter output. 5, record 3, English, - high%2Dpower%20modulation
Record number: 3, Textual support number: 2 CONT
Modulation is also identified as to level. High level modulation occurs when the modulating voltage is applied to the collector/plate circuit of the final power amplifier. With high level modulation, the final stage is operated class C and the preceding stages are also operated class C. The overall efficiency of such a transmitter is very high. A disadvantage of high level modulation is that comparatively high audio power is needed and several stages of voltage and power amplification may be required in the speech amplifier and modulator circuits. 4, record 3, English, - high%2Dpower%20modulation

The sub-modulator is transformer-coupled to the modulator comprising two valves M. A. 12/15000, which is also transformer-coupled to the anode-lead of the fifth H. F. [high frequency] stage, thus providing anode modulation in the H. F. power-amplifier stage. 3, record 4, English, - submodulator
