Interesting. I built an AR488 a while back (https://github.com/Twilight-Logic/AR488) and it worked alright for my needs. I'd be interested to see a comparison of the two projects.

Here a comparison from a user: https://github.com/xyphro/UsbGpib/discussions/47

  • Ooh! The faster speeds would be very welcome, I was bothered by the slowness of the AR488 but I assumed that was just how GPIB was (I had no baseline to compare to). I'll switch over when I get a chance.

    That user's project also looks very interesting - My TDS684A's CRT seems to have died, and rather than fix it I could switch to using a software scope.

    • The upcoming V3 adapter reaches even more than 1 MByte/s with my fastest instruments. Unless you connect long GPIB cables to it, because capacitive load slows down GPIB as it self regulates speed down in the way GPIB is designed.
