Abstract
A latching comparator has a signal input connected to the output of a device under test. A strobe input of the comparator has a strobe signal applied thereto, whereby the output of the device under test is repeatedly sampled. The output of the comparator drives an integrator, preferably through a filter. The output of the integrator drives a reference input of the comparator and a computer. The computer is driven via an A/D converter, whereby a digitized representation of the output of the device under test is provided to the computer.
