Hello;
First of all, we need to generate a valid waveform on one of the Analog Ouput channels of the terminal block.
You can open one of the LabVIEW shipping examples to accomplish that task. Choose the one named Continuous Generation.vi that you can find at Search Examples->I/O Inetrfaces->Data Acquisition->Analog Output. That VI will generate a continuous waveform to the chosen analog out channel.
Then, refer to your DAQ device Users Manual for its pinout. The DAQ device pinout is the same pinout of the SCB-68 terminal block. Then, wire both the Analog output channel number you are using on the Labview VI and the AOGND pin to the Scope.
Hope this helps.
