Abstract
A digital video probe system has a digital data probe for attachment to a data test point and a digital clock probe for attachment to a clock test point of a device under test. A clock signal from the clock test point is variably phase shifted by changing the duty cycle of the clock signal to produce a variable clock signal for processing digital data from the data test point. The processed digital data is converted to an analog video signal and displayed on an appropriate analog monitor. By varying horizontal and vertical sync inputs to the analog monitor the displayed signal may be moved about the display to assure that all of the processed digital data is displayed.
