I recently obtained a VGA/LAN module for my Agilent MSOX-2024A because I wanted to show the screen on a projector. This replaced a third party 'DSOXLAN' card kit which I had assembled but never used. According to Murphy, the first thing I actually used the new module for was running a remote front panel display over the LAN. The update rate is nothing like as fast as the real thing, but that didn't matter as I am doing single shot acquisition anyway - basically supporting software development. It's good, in that you get every single pixel just like on the physical screen, but it isn't cheap. Unless you get lucky on eBay (like I did).
If you have an Agilent X2000 or X3000 series scope, I have a LAN card available cheap!
