SA22.c and Lady Heather

Sat, Aug 26, 2017 1:09 AM

I got in a SA22.c rubidium from RDR electronics and one of those interface boards that appeared briefly on Ebay last week (he had 6 for $7 each and they went fast... there is another seller that has one for $80).  The X72 code that I added to Lady Heather works with the SA22.  I'm still working on improving the software disciplining algorithm.

If you bought one of those adapter cards note that you will need a F-F adapter to use them with a standard serial cable.  Since the adapter has a male connector,  I thought it needed a null modem cable... nope... just more Symmetricom ridiculousness at work...

hi mark et al...

i was lucky enough to bet that that card was an sa22.c development board
and got one.

ordered the sa22 and please point me at the code as it develops.

thanks!

hi

i was prepping for some machine shop work on a heatsink for the SA22.c.

there seems to be an error in the designers reference and user manual on
page 22.

the bottom view drawing at the far low right shows a measurement of the
distance between the edge of the board and the hole just below and to the
right of the SAMETC connector... it shows a distance of 15.95mm.  my
measure is about 25mm...that's measured on the development board.

YMMV

thanks

hi

two pix that put to rest whether or not the dev board is really that:

also, i was wondering just what kind of lash-up they did at rdr to get the
test printout from LH.. clearly there is a nortel producing a pps that is
regularlly used with :LH.

back to work on the machining specs
