The DSHA option works on my DS1074Z. It's now a DS1104Z. Thanks! :-+ Unfortunately I don't have a real signal generator. Thus I can't measure the bandwidth. But it has a faster rise time now.

I had the 500uV option installed before. Yes, there is a DC offset which is not adjusted by self-cal.

Edit: I have measurement history now. ;D And i think the region (gated) measuring mode is also new. They are in the 2nd page of the measure menu. Is that the unknown option?

Also, new firmware was released for the DS1000Z scopes a few days ago, any compatibility issues?

It works fine, and fixes a lot of bugs.

Thanks, it seems to be working well here, too. :)

The features discovered by Sync seems to be available only in the new firmware (00.02.01 SP1).
Marc M.:
Has anyone had any luck with downgrading the firmware on a 2072 (1.0 H/W) from 00.02.01.00.03 back to 01.01.00.02?  When I plug a flash drive in with the older firmware it doesn't detect it, but it does if I put .03 on the drive via the Boot & Help method.  When I uninstall all the options, my model under system still shows DS2202 not 2072 :(.  This wasn't an issue with the .02 version which allowed downgrading.  It seems Rigol have prevented doing so in the .03 update.
 
Success!  Thanks Marmad for confirming it should work.  For some reason it didn't like the SD card I was using.  It's the same card I've been using with the scope for both firmware and screen shots since I purchased it.  I used a different card and had no problems with the downgrade  :-//.  However, the scope was still showing a 2202 model number even after downgrading and clearing the FRAM (I had all options uninstalled at the time of the downgrade).  I reinstalled the options then uninstalled them via SCPI, power cycled the scope and the model finally reverted back to 2072.  Now I won't have to worry when I send it in for warranty repairs.
