Controlling PXI soft panel programatically?

[Sara_J]

I have an NI PXI-5112 Oscilloscope. I need to set the Time Per Division. It's fairly easy to do this on the soft panel, but I would prefer to make the change programatically rather than requiring the user to do it manuaully. Does anyone have any ideas on how I might accomplish this task?

Use the driver. You can either use the IVI Scope class driver or the NI Scope driver directly. The driver should have come with the card and if you've installed it, it should be on the Instrument I/O>Instrument Drivers palette.

Thank you for your kind advice, but I am unable to find this function in the driver VIs--hence my question. I was hoping that someone would either be able to point me in the right direction within the driver or confirm that this functionality is not available. My apologies if this was not clear.

Sorry that I didn't understand your question. If I remember correctly, you use either Configure Horizontal or Configure Horizontal Rate. When you turn a scope's time/division knob what you're actually doing is defining such things as sampling rate, record length, etc. and that's what the driver's VIs do.
