EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60107-5 testing. The measurement methods described in this part of IEC EN 60107 apply to television receivers designed for reception of television broadcasts in a two-channel digital audio system.
The audio coding system is based on NICAM 728 and is transmitted by a quadrature phase shift keying (QPSK) modulated digital subcarrier.
The purpose of this standard is to provide a standardized approach for measuring the electrical characteristics of multi-channel audio television receivers using the NICAM two-channel digital audio system. This includes measurement of frequency response, signal-to-noise ratio, distortion, intermodulation and other parameters that affect the quality of the audio signal.
The standard specifies the test equipment and procedures to be used for each measurement. This includes the use of a signal generator, an oscilloscope, a spectrum analyzer and other specialized equipment. The standard also provides guidance on calibrating test equipment to ensure accurate and repeatable measurements.
Overall, the standard provides a comprehensive and standardized approach to measuring the electrical characteristics of multi-channel audio television receivers using the NICAM two-channel digital audio system. This can help ensure that these devices meet required quality standards and operate reliably in their intended applications.
Each part of this standard provides recommended measurement methods for the respective television receiver type. The standards specify the test equipment and procedures to be used for each measurement, as well as guidelines for the calibration of test equipment.
In general, the IEC EN 60107 series of standards help ensure that television receivers meet required quality standards and operate reliably in their intended applications.
