I used the stratix because i had a eval board for it on hand, for cost reasons i would not recommend this family ! Cyclone3 are pretty good and Lattice has low cost FPGAs with build in SERDES for high speed interface so i would go with one of those.
Who said that i have given up on the gears ? i havent , as a matter of fact one of my former motorola coworkers offered a 8640B with problems as a parts mule for just that purpose !
As soon as i finish painting and setting the machine up i will start on it

I have read with some amusement and disappointment the responses you
received from your offer to make gears for people. I personally thought
it was a great offer and as soon as I need any gears I'll send you an
email. Never look a gift horse in the mouth!
After studying how a lot of rich people got rich I have discovered one
of the answers. They do what they enjoy doing without thinking of
getting rich. Entrepreneurs don't care about money as much as they care
about what they're doing to make it. HP started two guys doing what
they wanted to, Apple, Intel and most other super businesses all have
that in common. Certainly lots of people do jobs they don't like but
those that start from nothing usually make it doing something they
like. The hard part is knowing WHAT you like to do!!! Once you
discover that, you'll do it well and the rewards will come from being
the best.
Now after that little philosophy lesson ; I chose an 8565 over an 8569
because after watching ebay for several months, it seems that the extra
cost ( >in $AU 1000) was not justified. I can do digitisation - its
what I do for work and the ADCs available now are cheaper and faster and
everything else better. What is important to me is the RF capability
which is almost identical with option 100 on the 8565 - and outside my
current home construction and design capabilities!! So for $1000 less I
have an SA that does what I want rf-wise, I have already designed and
built a USB digitiser that I can use with it - more capable than the
8569 HPIB. But I'd like to have it all self contained in the one box -
so I will probably start to modify and hack the display section anyway.
Lothar - Thanks for the tip on LCD screens -I will look into that. The
Stratix chip is the one I was thinking of using. The reason I was
looking at high speed ADCs was to implement the rosenfell system HP uses.
Have fun!
See you later

If many of the great inventors would have shown this attitude than we
would be without a phone, light or electricity and the laws of basic
electronics would never been written!
Lets face it, many of the great inventors didnt start out because
they wanted to make money, they were tinkerers who liked to dabble
around and wanted to make things better, true in many cases wealth
and large companies came out of the original invention but it was not
the primary concern of the guy when he spend countless hours, days
and month sometimes years in the lab going trough trial after trial
facing the riddicule of friends family and sometimes even peers !
There are still many hams designing microwave circutry and publishing
detailed instructions on how to build their creations in magazines
for anyone to build without asking for any compensation.
Lets take for example Michael Kuhne DB6NT of germany who pioneered
many easy to build 10,24 and 47GHz designs, he did all the work in
his spare time, published many instructions and articles in DUBUS and
traveled from SHF convention to convention to promote his designs and
to answer questions from newcomers on how to build and improve those
designs, all on his own money without any commercial interest !
True sooner or later a company resulted out of it and today kuhne
electronic is good in business but it was not the primary idea of
michael when he started designing his stuff !
Sometimes we just need to step back and do things out of technical
interest without asking the $ question first, after all the good book
tells us that who seeks his rewards on this earth shall get their
rewards here and not in heaven !
