That doesn't make much sense if you are using the PICDIV properly... the TAPR dividers use the PICDIV chip to do the dividing. The only difference between using a TAPR divider and a bare PICDIV is that the TAPR dividers have an input squarer circuit and output buffer. If you are feeding the PICDIV with a clean TTL level input (and decent power) and the output from the PICDIV is not being abused/overloaded/improperly terminated the results should be the same.
> the similar problem I have verified using the HP5065A and HP5061B 1PPS output, the dividers are pratically unusable for ADEV measurements. The 5/10MHz output of the same instruments using the TAPR divider are ok, so these dividers have some spike noise problems. It can be seen even using other TIC as The HP53132A.
