Referencing the conversation about squaring circuits, I realized the T2-Mini
board (intended as a tiny PIC-based PPS divider) can be repurposed into a very
nice squarer.
It has a slightly modified version of the Wenzel squarer and by simply
installing a jumper wire instead of the PIC chip (pin 2 to pin 3 of the PIC
socket), it will put a nice TTL-level, squared, version of the input signal on
the output connector.
The T2-MIni manual is at http://tapr.org/~n8ur/T2_Mini_Manual.pdf and you can
order the semi-kit (all surface mount parts installed, connectors provided but
not installed) at http://tapr.org/kits_t2-mini.html
This is how I have modified my two TADD-2 and mentioned multiple times
here on the list. The improvement in measurement performance is
noticeable and when using my DTS-2070 it is very clear that you move
from signal-limit to counter-limit.
Cheers,
Magnus
