John, I knew we had that conversation before, you gave me your scripts when I was writing my Visual Basic program to do the same thing under Windows. This program is in a perpetual state of being messed with to reach ever changing objectives, but I have been using it for various logging experiments.
I bought my HP 59307A for something like $10 on eBay.
