Fellow time-nuts,
I've modified my TADD-2:s by sniffing the input clock on pin 2 of the
PIC and wired it over to the output 6 signal selection pin header where
it goes further to the output polarity inverters and finally output.
This way I can use the input shaper of the TADD-2 and output driver to
improve my sine signals slew-rate.
The TADD-2 only generates 5 frequencies (it has two variants of 1 Hz, 1
Hz and PPS) so I thought I could use one of the outputs for this purpose.
First test-runs shows that I have now lowered my measurement floor at 1
s from 2,83E-11 to 1.05E-11. This could be improved on by removing some
unnecessary damping needed until I have DC-blockers in place.
I think the modification is encouraging as it stems from only adding a
wire and un-jumping a jumper.
Cheers,
Magnus
