Abstract: A method and a measuring device for synchronizing measuring channel assemblies are provided. A reference signal is produced by a reference signal source. The reference signal is supplied to the individual measuring channel assemblies of the measuring device. A clock signal generator is used to produce a clock signal at a low frequency, the clock signal generator being connected to each measuring channel assembly by a respective connecting line of the same length. The clock signal is supplied through a phase corrector element for the purpose of correcting the phase of the reference signal in each measuring channel assembly to the phase of the clock signal.
