The built-in system of parameter measurement for wideband (up to 512 MHz) receiving and recording channel of radio interferometer is considered. The estimation of measurement accuracy and the precision alignment of group delays in the receiving channel are investigated. In addition, this system provides the control of receiving channel frequency response and phase response functions.
