Hi Magnus,

The 5372A which we bought new years ago reference polluted by the  
switching power supplies. There were more of them with different  
frequencies. It showed up in the fft of measurements and also seen at  
the reference output. I do not have access to that instrument anymore  
and do not know the serial number. How is this with your 5372A?
