Hi VA3RR
Thanks a lot for the help.
I conlude that MS5153 may be a little bit better to go up to 300Mhz lnstead of 290Mhz for SI5351A and also a little bit better for harmonics measurement with few db deeper, the jitter noise do not conserne our NanoVNA typical application , no matter how it is with both,
But wondering why firmware do not consider them as similare sheeps , what can be the changes with firmware ?
