Abstract
Apparatus for testing data conversion/transfer functions in each of a plurality N of channels of a vibratory energy imaging system includes a multiplexer for providing, to an addressable memory having a plurality of L=2.sup.M locations in each of which a data word of B bits can be stored, a selected one of an input data word and a test data word, each of which can address one of the L locations of the memory means. The address multiplexer facilitates retrieval from memory of a B-bit data word having a value selected to implement a selected function for that channel, so that comparision of data from the selected test address with the data which has been sent to that location for storage, will indicate if proper data is stored for carrying out the designated function.
