BS EN 60244-8:1995 Methods of measurement for radio transmitters - Part 8. Performance characteristics of vestigial-sideband demodulators used for testing television transmitters and transposers
Printed version of this standard is available at Library. To request, please e-mail to referencepk@usm.my and include a copy of this record in your e-mail.
This part of IEC 244 is intended to be used for type tests and acceptance or factory tests and may be used to check the characteristics of a demodulator used for measuring television transmitters and transposers. It is not mandatory to measure all the described characteristics.
Additional measurements may be carried out by agreement between customer and manufacturer. bas sime
Measuring performance, characteristics in accordance with this standard, makes the comparison of the results of measurements, made by different observers, possible. Limit values for acceptable performance are not normally specified, but, in connection with the presentation of measured characteristics, some figures can be given for the sake of clarity.
