Anritsu FAQs
Why does my MS2721B give me an input saturation warning when other instruments don't?
The MS272xB, MS271xB, MS2711D, MT8222A and MS20x6A are equipped with a broadband detector that is designed to sense signal levels at the input to the first mixer that may cause inaccurate measurements due to saturation. Most competitive instruments don't have a method to deliver such a warning and allow the user to take measurements that likely are inaccurate. These inaccuracies can include lower amplitude values and the generation of signal harmonics due to mixer saturation.
