There's a whole lot of crap software coming out of Rigol.  Hackability or not, I won't be buying Rigol in the future, probably.

Rigol's PC software is pretty bad in most cases.  Rigol works great with custom VISA software like labview.  We've switched most of our test equipment from Tek TDS3000 series to the DS1074.  That's a 5x savings on the scope.  Rigols hardware is solid, firmware is a little buggy but the PC software is bad.

Agreed on all points.

Rigol's software (and their support in general) is not very good.  Pretty good hardware, though. 

To get Ultra Station to work you need to edit "Ultra Station.ini" located in \Rigol\Ultra Sigma\Instrument Tools\ folder.  Add or edit so you have DS1104Z,DS1074Z listed i.e. without the -S.  Once you do this, you should be able to right-click on the instrument in Ultra Sigma and choose Ultra Station.  Ultra Station must be run from within Ultra Sigma.

The DS1000Z and DS2000 series do not distinguish the -S and non-S models.  As mentioned above, The DS2000 series seems to work OK, but the DS1000Z doesn't process and output the arb data.

If you could perhaps do a packet capture on the series of commands that gets sent to the scope, I'd sure appreciate it.
