A test and measurement system for synchronizing multiple oscilloscopes including a host oscilloscope and at least one client oscilloscope. The host oscilloscope includes a host timebase clock configured to output a clock signal, a host digitizer including a digitizer synchronization clock based on the clock signal, and a host acquisition controller includes a trigger synchronization clock based the clock signal and outputs a run signal to begin an acquisition of an input signal. Each client oscilloscope includes a client timebase clock configured to receive the clock signal from the host timebase clock and output the clock signal, a client digitizer including a digitizer synchronization clock based on the clock signal, and a client acquisition controller includes a trigger synchronization clock based on the clock signal and receives the run signal from the host acquisition controller and begins an acquisition of another input signal based on the run signal.
