Analog Electronics with LabVIEW®

PA.8. Using the Simultaneous Sending/Receiving Function

With Chan0_out and Chan0_in connected on the circuit board, open FG_A_2.vi. Also open SR_A.vi and OscilloscopeA_2.vi. Open these from Browse>>Show VI Hierarchy. Run the top VI for various Vs and VDCout values. Run the VI at various frequencies and note the change in Cycles and Sample Rate. The number of cycles is increased with frequency automatically to offset delay between sending and receiving. Note the Number of Samples in the array as indicated in the Front Panel of SR_A.vi, for the various changes. Run the VI with SquareWave selected. In the example, VDCout = 5 V and Vs = 0.1 V. There is a slight offset in this example. The oscilloscope’s high limit and low limit are set for 10 V ...
