Hi,
The best resource for functions like this would be the NI-SCOPE help file. You can access this file through Programs >> National Instruments >> NI-SCOPE >> Documentation >> NI-High Speed Digitizers help. This will open an HTML file for you where you can see all the functions, details about what the function does and details about the parameters used in the function.
To see what function could be used for the setting the horizontal parameters, you can browse to Programming >> Reference >> NI-SCOPE Function Reference Help >> Functions >> Configuration Functions >> Horizontal.
You can also find information about all the other NI-SCOPE functions in a similar manner. There are also Visual Basic examples that are shipped with the NI-SCOPE driver, which you can use as a resource.
Hope this helps.
Regards,
