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) Also @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)"; |

I got a confirmation from Rigol, that the 500uV mode is a scaled mode. |

I am glad , I have 500uV/div, with 200uV Noise @BW=20MHz and 20 uV resolution, how ever it is derived. |
