trouble in plotting waveform graph for real time signal to labview 8.2

[tronoh]

Dear All

My signal is out put of current transformer which is 2v dc. I succesfully configure usb 1208fs with labview8.2. Now I want to plot my input signal on the waveform graph in frequency vs amplitude(db). Can any one guide me how can i plot my data?

Hi tronoh,

To plot frequency vs. amplitude, you could use a XY Graph with frequency (obtained from an FFT) and amplitude as inputs. Then change the Y axis scale by right-clicking on the graph and selecting Properties. In the dialog box, go to the Scales tab. Select the Y axis in the drop-down box and then check the Log box.

Also, this seems to be a different issue from the one initially addressed by this thread (also, this thread is an old one). For better assistance, post different issues in new threads.
