IEC 60107-5:1999 电视广播接收机的推荐测量方法.第5部分:使用NICAM双声道数字音频系统多声道电视接收机的电气性能测量

The methods of measurement described in this part of IEC 107 apply to television receivers designed for the reception of television broadcasts using the two-channel digital sound system. The sound coding-system is based on NICAM 728 and is transmitted by a quadrature phase-shift keying (QPSK) modulated digital subcarrier. NOTE - NICAM 728 is the abbreviated form of Near Instantaneous Companded Audio Multiplex at 728 kbit/s.

IEC 60315-3:1999 各种发射类别的无线电接收机的测量方法. 第3部分:放大调制声音播送接收器.

This standard applies to radio receivers for the reception of amplitude-modulated sound-broadcasting emissions. It deals mainly with measurements using radio-frequency signals applied to the antenna terminals of the receiver, or induced in a magnetic antenna. This part is intended to be read in conjunction with Part 1 (IEC 60315-1, Second edition). Immunity is not covered, except for an explanation with cross-reference to CISPR publications. For radiation from receivers, reference is required to CISPR Publication 13. NOTE 1 - Receivers without volume controls or a.f. power output stages ("tuners") are included. NOTE 2 - Receivers for single-sideband and independent-sideband emissions are not included, nor are receivers for stereophonic emissions as far as characteristics involving the encoding system are concerned.

ITU-T O.9-1999 关于地球的评估不平衡程度的测量安排.系列O:测量设备通用规范研究组4

This Recommendation describes arrangements for measuring the following parameters: - longitudinal conversion loss; - transverse conversion loss; - longitudinal conversion transfer loss; - transverse conversion transfer loss; - input longitudinal interference loss; - common-mode rejection; - output signal balance. In practice, the above parameters are the seven most significant unbalance parameters. Limits for these parameters, special considerations for terminating impedances and the measurement frequencies to be used are given in the relevant Recommendation for the item under test. This Recommendation is in agreement with the principles, the nomenclature and the definitions, addressed in Recommendation G. 1 17 [ 11, which considers the transmission aspects of unbalance about earth. References are made in the following clauses to the appropriate parts of Recommendation G. 1 17 [i]. In clause 5, guidance is given regarding the construction of a test bridge along with values of the required components.
