A tool for designing arbitrary waveforms

[Warhawk]

Hi guys,
I am looking for a software which would help me with designing arbitrary waveforms for my AWG from Rigol (dg1022u). I know that Rigol has the UltraWave package but I could not get this bloody tool running. Neither under wine, nor in Windows 7. It just reports some exception handler and crashes. Does anyone have a tip for software which allows graphically drawing different waveforms and exporting them into some readable format? If it ran in Linux, it would be brilliant.

I googled but probably could not figure out the right magic formula.

Thanks, Jiri

Matlab? Excel?  I use LabVIEW myself.   I'm sure there are a few choices out there.

Matlab, Excel, they don't allow for drawing the waveform by hand. I wanted to avoid putting there numbers manually.

Maybe write the equations to derive the waveform?  I've used various equipment to record various waveforms that I wanted to playback. 

Drawing the wave shouldn't be too bad.  Maybe just use a standard CAD package.  Save the files in a standard format and write a conversion.   Back in the stone ages, I did something similar.  Built a custom Arb and used a hand scanner to capture a waveform and then converted it.

You could even do it in Excel, if you define a Baseline (or do it inverted), mark the cell corresponding to the amplitude with something and then write a macro giving you the non-empty cell for all consecutive columns.
Then normalize/convert to format used by generator.
(not a recommendation, but feasible nearly everywhere)
