Abstract
In an exemplary embodiment of the present invention, a master oscilloscope propagates a slave signal to one or more slave oscilloscopes. The slave signal includes a synchronized trigger pulse that is used in the master oscilloscope to provide a display of a first signal and also includes a timing interpolation parameter which indicates a timing delay applied in the master oscilloscope with respect to the synchronized trigger pulse when providing the display. A slave oscilloscope can use the synchronized trigger pulse and the timing interpolation parameter to provide a display of a second signal on the slave oscilloscope, thereby ensuring that a triggered edge of the second signal is time-aligned with a triggered edge of the first signal. This arrangement reduces/eliminates absolute as well as relative timing uncertainties when an observer observes the first signal displayed on the master oscilloscope and/or the second signal displayed on the slave oscilloscope.
