REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol
Teneyes:
SO, I generated a ramp to test the 500uv & 1mV resolutions and see what the output to the CSV File is like.
Below are the pix
1 DSO display
2 A section of Excel csv file from 1mV/div, with added columns for:
Fix Point Format (volts)
uVolts and
change between last data point in the CSV file
3 A section of Excel csv file from 500uV/div, with added columns for:
Fix Point Format (volts)
uVolts and
change between last data point in the CSV file
Note" the section of data is near the 0.0 Volts value, ie @ sample 1400 in 2.8K
I see for 1mV/div the resolution is 40uV in the data samples (delta = n*40)
And for 500uV/div the resolution is 20uV in the data samples (delta = n*20)

@Xyphro
I do not fully understand your Histogram and I would like to see the histogram with the Axis switched (0-200) on 'X' and show bars for number of samples occurring for each voltages level. maybe try "hist(sig500uv, 256)";
Xyphro:
I got a confirmation from Rigol, that the 500uV mode is a scaled mode.

For my own work I don't particularly care, but they should REALLY note that in their documentation.
Would you mind posting their exact response?
Teneyes:
I am glad , I have 500uV/div, with 200uV Noise @BW=20MHz
and 20 uV resolution, how ever it is derived.
