Filename: convertfromddr.vi
Requirements: View

This is the VI that is referenced in the Application Note entitled "Generating Double Data Rate Waveforms with NI Digital Waveform Generator/Analyzers." It is intended to be used only with the setup described in that document.

This VI will take an array of DDR samples and convert into a format that can be used with an SDR device and a fast XOR gate. Each bit of the input DDR data is associated with certain bits of the output array. For example, the data on bit 0 of the input will be processed with the result being placed on bits 0 and 1 of the output.

This VI will then save the resulting data into an HWS file specified in the file path control.
