A digital signal transmission channel degradation monitor for determining the error rate in a received data signal includes circuitry to generate an eye pattern signal for the received data signal which eye pattern signal is applied to a grid containing a number of cells defining regions in an ideal eye pattern. Each cell contains circuity to count the number of time an eye trace is located in that particular cell over a predetermined period of time. A number of cells within the ideal eye pattern area are grouped to define a predetermined pseudo error region. The number of times an eye trace enters into that error region over a predetermined time provides an indication of the generalized pseudo error rate for the transmission system. In addition, the number of times an eye trace is located in particular cells through the grid over a predetermined period of time can determine the type of stress that the transmission system is undergoing. This detector can be automated to determine both the error rate and type of stress for the data transmission system.
