Hello All,
I am using Tektronix MSO5034B oscilloscope for one of my project and using its official driver to control and get data from it. In "Configure Timebase.vi", the timebase setting is confused. I though "Timebase" is for inputting time/div, so i tried multiple time/div settings in the box but it always sets its time/div to lowest value and the sample rate is fixed at 5Gs/s.
So, if I have desired time/div value, how to convert that to "Timebase", "Position" and "Record Length" values? Also, if i given these 3 values, how to find out time/div value?
Thanks

For those who may have this question, I do have found a way around.
Sampling rate of Scope = Record length / Range
Where range is entire horizontal width of oscilloscope time range which is given below as
Range = Number of divisions * Time/Div
For almost any oscilloscope, number of divisions in horizontal axes are 10.
And time/div is desired value.
For me max sampling rate is 5GS/s and record length is number of samples taken in entire visible window of scope.
hence, Sampling Rate = Record Length / (time/div * 10)
In above calculation, just make sure you do not cross your sampling rate provided by vendor. This calculation holds till 500ns/div, after that does some weird behaviour which I am still working on.
