I like the metal encoder spindles. :-+
Jason:
I'm intrigued by those SPI pins. Has anyone tried using them?
Evi:
Strange thing. When my scope arrived I of course made self-calibration and lost all trials. But yesterday I switched it on and suddenly saw all trial with the time left about 1200min. It was no any actions from my side. Then I update the device to 01.00.00.00.03 and all tials were kept.
BTW. Does anybody succeed with Rigol support. I sent numerous mails to support@rigol.com and from the feedback form from Customer Center. It seems they are in permanent meditation or dead.
MikeR:
Are you able to obtain waveform data that is 2GS/sec ? Everything Ive tried results in a file containing 1GS/Sec data. Ive set horizontal to max, memory depth to 56Mpoints, 14, 1.4, aliasing on and off - scope says 2GS/Sec on the display but always outputs 1GS/sec to the wavefile. Acquire mode is normal.
To check the scope. It "seems" to be sampling at 2GS/sec. I generated a 10 - 950 Mhz sine wave sweep at -20dBm and it displayed it on the FFT. Its a bit iffy above 200 Mhz.
What I did, Capture an antenna with broadcast FM present at 2GS/sec, loaded that into baudline and checked the position of the stations. None of the saved files were recorded at 2GS/sec, all were 1GS/sec.
My model is the DS2072. Firmware 0.0.1 according to the LXi welcome page.
Buggy firmware ?
-Mike.

To check the sampling rate, all you have to do is STOP acquiring when it displays '2GSs/s', then change the timebase to the smallest possible (e.g. 5ns), switch 'Display' -> 'Vectors' to 'Dots', then count the actual sample points. 2GSa/s means a 500ps acquire time for the ADC, so at 5ns/div, you should see 10 dots per div. If you don't, then I would imagine you have a technical problem.
