After importing analog signals it is sometimes necessary to export them using a different sampling frequency. To resample signals in a diagram, first add a clock signal with a frequency that equals the new sampling frequency. Then export the waveforms to the spreadsheet format and then re-load the newly sampled signals.
•Add a clock signal to the diagram of the desired sampling frequency. When you export, the other waveforms will be sampled on the positive edge of this sampling clock. •Select Import/Export>Set Export Clocking Signal menu to open a dialog, and set to the newly created clock signal. |
•Export the diagram as a "Test Vector SpreadSheet Clocked" (the Clocked keyword here is very important as there are other test vector export formats). This new file will have have points at the sampling frequency of the clock. •Import the file exported in the previous step as a "TestVector Spreadsheet" file to see the signals with the newly sampled waveforms. |
