1. A main measurement device for simultaneously measuring signals with at least one secondary measurement device, the main measurement device comprising:
a reference signal output port configured to couple to the at least one secondary measurement device;
a reference signal generator coupled to the reference signal output port and configured to generate a reference signal;
a measurement port configured to receive a signal to be measured;
a trigger output port configured to couple to a trigger input port of the at least one secondary measurement device and to output a trigger signal; and
a controllably switchable internal signal path configured to selectively couple the reference signal generator internally with the measurement port.
