Hi With any DMTD, the offset between the LO and the DUT is a critical part of the resolution. Without much info on the LO, it is not very easy to work out just what they might or might not be doing.
That said, with “normal” offset frequencies, a filpflop would be challenged to hit the sort of resolution they are claiming. They might be using XOR gates …. Indeed all of this is why some of the competition went with a DDS for the LO.
