Abstract

Presented embodiments facilitate efficient and effective flexible implementation of different types of testing procedures in a test system. In one embodiment, a tester system diagnostic method includes forwarding test signals to a loopback component; receiving the test signals from the loopback component; and analyzing the test signals to diagnose whether or not the test system is experiencing problems associated with electrostatic discharges, including analysis of eye scan configuration data corresponding to characteristics of the test signals. In one exemplary implementation, analyzing the eye scan configuration data, including analyzing symmetry of a graphical representation (e.g., eye pattern, eye diagram, etc.) of the eye scan configuration data with respect to a horizontal graphical representation axis.
