Abstract
A method for diagnosing card failure in a data processing magnetic tape READ channel. An input signal of a nominal amplitude is applied to the READ channel and the response time of the various components of the READ channel is determined, as well as the amplitude response of the READ channel. Card failure can be so identified to alert a user that repair action is needed, cut down diagnostic cost and error, by the field engineer to avoid data processing errors produced by a defective machine.
