REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol

<< < (361/566) > >>

Teneyes:
Here are displays of 100MHz on chan 1 , using Dots and different trigger sources ,all in Auto mode:.
   1st   Triggered on channel 1
   2nd   Triggered on Ext, NO input
   3rd   Triggered on Ext with Delay
   4rd   Triggered on channel 2
Question ,
 Am I understanding that the Auto start (for EXT)  is sync'd to the trigger display point?
but Chan 2 is not.

In response to the question of the jitter present in the Delayed Sweep mode (and whether it was a bug), a Rigol rep. wrote:

"I'm afraid it is universal "issues" of system, when the sampling rate down to 1GSa/s, it will be like that. As the matter of fact, the jitter remains in both main and zoom wave, but it's too small to see it in main windows."

...and included an image from an Agilent X-3000 exhibiting the same behavior:

Rigol has changed the structure of unit settings stored in FRAM memory in the newest FW version, so owners of non-A model DS2000's should follow these steps when upgrading to try to avoid potential 'hanging' issues:

1) Before upgrading - set Utility->System->Power On to 'Default'.
2) Upgrade via boot method.
3) During the first boot up after upgrade, hold in left-menu F6 (sixth gray button) during the boot to reset FRAM settings.

Please post any changes (improvements, bug-fixes, new bugs, etc) noticed here - and I will update the bug list as necessary.

Edit: New firmware available at Rapidshare link in Firmware post at the beginning of this thread.

marmad:
If using new FW 02.01.00.03, I strongly advise against loading WFM files created under a different FW version.

Doing so (at least on my DSO) immediately changes the language to Chinese - and then hangs before finishing loading of the file. A reboot will get you out of the hang, but many things will be screwed-up, and if you then, for example, go to Measure->Display All->On - you will hang the DSO permanently - unable to exit the hang even with a reboot - requiring a downgrade to older FW to restore it to working function.
