Measurement- time is distorted

[luban]

Hello, I want to display the time at a point on the X axis. The measurement using the cursor is OK, but the value is distorted using the Measurements window. Is this a bug or am I doing something wrong when displaying the time in the Measurements window?

Hi @luban

The T1/2 are rounded up/down from X# to sampling resolution.

Dear Attila, thank you for quick response and explaining. 
But I still think there is something wrong- as you can see on picture1 : the difference X1-X2 is almost 20ns but in measurements window is the same value. (Probably there is no way to see exact values of cursors in measurements window without rounding?).
And when X2 is lower than X1 , the values in Measurements are exchanged with each other (picture 2). But X1 is greater than X2 on the x axis. 
Another question about Measurements window: In my project I am calculating speed from this 2 points on X axis (simple calulating 1/(T1-T2).  I want to see result of this in units of m/s with decimals. This works only with choise AUTO in Precision, but only till the value is smaller than 1000 m/s. After exceeding this value, the result is rounded (without decimals) and in km/s or Mm/s (picture3). 
Is there a way to show it still in m/s with decimals? 
Sorry for so long  post, I´m newbie.

Thank you for your time

Hi @luban

Yes, the T1,2 are rounded up/down to the sample point. I used this rounding for the original/default visible measurement to take in consideration only visible samples. When adding cursor measurement followed the same rounding principle. The next software version round T1,2 to the nearest sample. This is probably more intuitive.

Thank you, I think it will be more understandable this way.
