vrf Can it or Can't it?

Question asked by VRFuser on Sep 22, 1999
We use HP's Benchlink Arb software to upload user shapes to our arbs. I've
personally sent all points because that's what I had to go by but another
engineer where I work programs the arbs using the front panel with start/
end points. I don't know about panel drivers. Never needed 'em. The files I
use are simple .csv comma delimited files I whipped up in Excel and saved as
.csv so Benchlink arb could read them. You can also send them using a direct
I/O object in vee. That's how I'd do it if/when I needed to.
