ABSTRACT:
High speed data monitoring apparatus for displaying the bit pattern of a selected portion of a block of transmitted data comprising a shift register for receiving the transmitted data and for temporarily containing the consecutive data bits therein, a programmable sync detector for monitoring the contents of the shift register and for generating a sync signal when the shift register contains a predetermined sync code, a counter for counting the data bits input to the shift register after the sync signal is generated and for generating a count complete signal when a selected number of data bits have been input to the register, a data storage device for storing the contents of the shift register at the time the count complete signal is generated, and a display for displaying the segment of data stored in the storage device.
