    Patent number: 5519719
    Abstract: A universal pattern generator generates a digital signal pattern. The generator includes a user programmable device for specifying a repeatable digital signal pattern. The programmable device allows for the selection of a framing structure having a number of channels. The programmable device also has input means for inputting data into the channels of the framing structure. A data set representing the repeatable digital signal pattern is generated. The data set is held in memory. A transmitter responsive to the data set held in memory repeatably transmits the repeatable digital signal pattern represented by said data set.
