Abstract
Test apparatus for monitoring transmissions contained in a broad band television video signal is disclosed including a sampling device operating at an integer multiple of the digital bit rate which is above the Nyguist level and a temporary storage device for storing the sample produced by the sampling device. A microprocessor is used to compute from the stored samples a value of a parameter of the digital transmission and to control the sampling device whereby the sample can be taken at appropriate points for the parameter to be tested. To that end, conversion means are provided for converting the stored samples so as to recreate the input digital transmission for resampling at the points determined by the microprocessor.
