Patent ID: 7933321

Claim:
A measuring system comprising: a signal generator configured to generate a digitally modulated high frequency measuring signal (MS) by modulation with modulation data (MD), the digitally modulated high frequency measuring signal is supplied to the input of a test unit, and a signal analyzer having a comparator device, the signal analyzer being connected to the output of the test unit and configured to analyze an output signal (OS) after demodulation thereof, wherein a direct connection exists between the signal generator and the signal analyzer, via which connection a reference signal (Ref) of the signal generator is supplied directly to the signal analyzer, and wherein the reference signal (Ref) includes a synchronization training sequence (TS) that is transmitted within a signal portion (SL0-SL7) of the high frequency measuring signal (MS) generated by the signal generator and wherein the training sequence in the reference signal is used by the comparator device for comparison against a demodulated output signal (DD).
