Figure 6-4 Test Load Circuit for Output Propagation Measurement

For output timing analysis, the tester pin electronics and its transmission line effects must be taken into account. System design should use IBIS or other simulation tools to correlate the timing reference load to a system environment. See #T4989946-26.
