Abstract
A system includes a plurality of oscilloscopes, each oscilloscope having an output port and an input port, a cable connecting the output port of an initial oscilloscope of the plurality of oscilloscopes to the input port of a second oscilloscope of the plurality of oscilloscopes, the initial oscilloscope having a processing element to generate a master run clock, the second oscilloscope having a processing element including a phase-locked loop to lock a slave run clock to the master run clock, wherein the processing element of one of the oscilloscopes executes code to cause the processing element to manipulate one of the run clocks to pass trigger information to another of the plurality of oscilloscopes. A method of synchronizing at least two oscilloscopes including a master oscilloscope and at least one slave oscilloscope includes connecting the at least two oscilloscopes together using output ports and input ports of the at least two oscilloscopes and at least one cable; sending a master run clock from the master oscilloscope to at least one slave oscilloscope; synchronizing a run clock of the at least one slave oscilloscope to the master run clock; recognizing a trigger event at…
