The DAC numbers were intended to express the scale of the problem and were rounded. Using a step of 5uV and 4.5mV of ground bounce (internal + external) the DAC count should be 900. At the time I never thought to measured the minimum and maximum voltages which are the numbers you want to know for EFC stability. I just soldered wires to various points then twisted them together and used a HP 34401A to measure the voltage difference. Unfortunately I never got a Z3801A.
