Guilty as charged... :-)
I'm actually about to start work on a version of 7470 that will support
this new, economy-priced GPIB adapter:
http://www.sparkfun.com/shop/index.php?shop=1&itemid=500
The guy who designed it came over a few days ago to try his latest
version out on the HP 8566B and a few other "challenging" instruments
here in the basement. If you can wait a few weeks, this board could be
one option for you. It is not a full-fledged GPIB bus controller
(meaning it can't be used to address specific instruments under host
control), but it should be able to handle device-initiated plots for
most of the equipment supported by 7470 and PrintCapture.

Thanks Joerg, John Miles pointed this out too. Apparently he is
modifying his 7470.exe GPIB plot capture utility to work with it.

What are the current recommended GPIB cards to do this? The "standard"
seems to be NI cards (ISA and PCI). These are quite expensive,
although seem to turn up on ebay. Any others? A low cost USB type
would be nice (if they exist), but unsure about compatibility with

Unless you are particlarly short of cash, save youself a lot of hassle
and buy a NI card on eBay. As you say, NI are the standard now.
ISA ones are very cheap indeed, but you will not get drivers for the
latest versions of Windoze.

Others have, but I personally would rather take some intersting
mesurements than mess about saving a few pounds whilst giving myself a
headache.
If you make one youself, it is extreamly unlikely to be 100% NI
compatable. So you might as well buy a used one from Computer Boards
(good choice) or similar, which will cost even less than a NI one, and
probably more compatable than anything you could make in a reasonable
period of time. |

Done. The card just arrived today!
Working very nicely so far - can download plots from spectrum analyser
and dynamic signal analyser. I am using a demo version of PrintCapture
on Windows to get everything working. Next step is to do the same on
Linux. I need to figure out how to put the interface into "listen"
mode and capture the HPGL data into a file. Something for the weekend!

Agreed, I was not really thinking of making one myself. I thought
someone else might have something on sale that was compatible and
cheap...

Not true. Some of the old ISA cards are still supported under at least
Windows 2000, and I believe Windows XP. Somewhere on their web site NI has a
chart showing which cards is supported by which OS.
We did end up stuck with NI's first USB --> GPIB converter that they supported
under Windows 95 and 98 and then dropped support for in later OSes! @#$@#$% |
