Calibration Procedure for Video Equipment

Since the video signal - composite or component - is a most complex one regarding the spectral density or even the group delay in the baseband, you need special procedures to measure the signal parameters with an objective and absolute accuracy of less than one percent over the whole frequency range up to 6 MHz. The following describes a method allowing the precise measurement of a baseband signal, which then may be taken for the calibration of video analyzers such as the well-known R&S units UAF or UVF and future products.
