How to Configure the Vertical Range Per Channel of My National Instruments Digitizer?



Hardware: Modular Instruments>>High-Speed Digitizers (Scopes)

Problem:
I have an NI-SCOPE device and would like to adjust the Channel 0 vertical range independently of the Channel 1 vertical range. I have tried using the niScope Configure Vertical VI but it changes the settings for both channels. How can I change the vertical ranges independently?

Solution:
The vertical range for both channels can be configured with multiple instances of the niScope Configure Vertical VI or by using property nodes. Each instance of the configuration VI has a required input, Active Channel, that designates which channel to apply the property to. Figure 1 shows the vertical range of Channel 0 configured as 1 Vpk-pk, followed by the vertical range of Channel 1 configured as 10 Vpk-pk.

The same effect can be achieved by using property nodes, as seen in Figure 2. This method is more compact, as both channels can be configured with one property node.
