41、ELECTRONIC TUBES AND VALVES Part 10: Methods of measurement of audio-frequency output power and distortion i. Scope This Recommendation is based on current practice of the measurement of audio-frequency output power and distortion. It should not be regarded as a Recommendation in the sense of a stan

42、dard, because a more detailed description of the measuring methods is needed if measuring results on the basis of these principles have to be comparable within definite tolerances. 2. 2.1 2.2 Audio-frequency output power DeJinition (IE V 07-27-100, second edition) supplied to the load by the electro

43、nic tube or valve at the output electrode. Methods of measurement The measurement is carried out by applying to the input electrode of the tube or valve a sinu- soidal signal of given frequency and amplitude. The frequency is in general chosen between 400 Hz (c/s) and 1 O00 Hz (c/s). The voltage of

44、the output electrode (r.m.s. value) should be measured between the point where the load is connected to the output electrode and the reference point, the signal being applied to the input electrode. The load resistance may be inserted either directly into the tube or valve circuit (Figure 1, page IO

45、) or by means of a choke and a capacitor (capacitance coupling, Figure 2, page 10) or through a transformer (Figure 3, page 10). In these latter two cases, the reactances of the coupling devices shall have a negligible eect. The output power of an electronic tube or valve (operating at audio-frequen

46、cy) is the power Measurement of the voltage at the terminals of the load resistance, or of the current in its cir- cuit, enables the output power to be determiried; if a choke or a transformer is used, the resultant loss shall be added to the measured output power. 2.2.1 2.2.2 2.2.3 2.3 The power me

47、asurement can be carried out by taking as a parameter: Either the excitation voltage on the input electrode, in which case, the corresponding output signal distortion may also be measured. Or the output signal distortion, in which case, the corresponding excitation voltage on the input electrode may

48、 also be measured. Or the point of start of positive grid current for the input electrode, in which case, the corresponding output signal distortion may also be measured. Precautions The supply sources should be correctly decoupled. The impedance of the signal generator should be low compared with t

49、he minimum impedance of the input electrode, in order not to introduce any noticeable distortion if an input electrode current starts to flow. -6- Les instruments de mesure en courant alternatif doivent mesurer les valeurs efficaces quel que soit le facteur de forme. 2.4 Conditions de mesiire Pour chaque ty
