I am using Tektronix MSO5034B in one of my project through LabVIEW. In the NI driver for scope to set the timebase "Configure Timebase.vi" is given with 3 controls "Timebase Range", "Position" and "Record Length". There is no straight control to set time/div.
How to find out the values of these 3 parameters from desired time/div? Also, How to find time/div value from these 3 values?
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.
