My IMD bench is:

Would it be not less effort to use two well buffered X-tal Oscillators instead of an Si5351 followed by two x-tal filters? I do it this way with a RF-2-tone generator proposed by DC4KU and are able to measure with a Siglent 3302 an IP3 up to 36 dBm without bandstop filters. To achieve a higher measuring dynamic range bandstop filters are mandatory.
