IEC EN 60107-7 Measurement Methods in Television Receivers - HDTV Screens

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60107-7 testing. This part of IEC EN 60107 deals with standard conditions and measurement methods in high definition television (HDTV) displays.

IEC EN 60107-7 Measurement Methods in Television Receivers - HDTV Screens

Such screens can be used, among other applications, as an integral part of an HDTV receiver for direct over-the-air reception, reception via cable networks, or as a monitor for pre-recorded video, home movies and games.

This standard deals with the determination of performance and allows comparison of equipment by listing features useful for specifications and specifying uniform measurement methods for those features. Performance requirements are not specified.

To ensure reproducible results, the measurement should be made in accordance with the following conditions. If sound channels and loudspeakers are provided, the characteristics of the sound channels shall be measured by the methods specified in IEC EN 60107-2.

While taking measurements, all test conditions or operations that could cause damage to the display should be avoided. This is especially true for sensitive, solid-state devices and similar structures. If the protective cover is removed and directly connected parts become accessible, the equipment must be connected to AC.

It should be determined that the use of a safety transformer does not affect the receiver characteristics to be measured. In particular, the internal impedance of the safety transformer must be low enough so that the behavior of the screen is the same as when connected directly to the mains.

Additional measurements at overvoltages and undervoltages may be needed to determine the effect of changes in supply voltages on the display properties, these are appropriately selected taking into account the manufacturer's specifications.
