Adding offset to LabView Signal Express signals

We are using a USB 6535 with LabView Signal Express. 

The logging need is to record 8 channels of data, with each having 3 unique (0->5V) signals. 

So far, only the first channel has been wired in an the logging inputs set up.

With a standard scope, there are offsets to offset a signal vertically, and to thus see the overall time relationship. 

How is that done with LabView Signal Express? 

Each channel's 3 signals need to be grouped together and then 8 channels vertically offset for visibility.

 

Thanks

Hello,

 

The best way I can think of is to create a constant signal (or however many you'd need) and add or subtract to the signals you are acquiring.  In SignalExpress, there's an Arithmetic step that is helpful for this.  The following KnowledgeBase article from our website offesr one way to do this in SignalExpress:
