The instrument requires waveforms to be a multiple of 8 samples, and a minimum of 512 samples. You can choose how the instrument processes waveforms that do not match the instrument’s requirements as follows:
None: No extension is done. A warning message is shown only if the length is not a multiple of 8 samples.
Warn: No extension is done. A warning message is shown if the length is not a multiple of 8 samples or is shorter than 512 samples.
Repeat: The original waveform is repeated until the length satisfies the requirements. This yields the highest fidelity playback at the expense of larger waveform files. This is the most applicable under Trigger Mode of Continuous where playback continues when the end of the waveform has been reached.
Zero Padding: Samples with I=0 and Q=0 are appended until the length satisfies the requirements. This yields the smallest waveform at the expense of discontinuous playback. This is the most applicable under Trigger Mode of Single; and if using Single Mode of Restart on Trigger, the restart will occur even if trigger received during the zero padding period.

Sets the default binary file format used when reading waveform binary files. This affects simple binary data only and does not affect other formats such as secure waveform (wfm) file and Matlab file.
Selections are:
Int16 Big Endian
Int16 Little Endian
This setting does not affect the data currently selected. For example, if a binary file is selected by the File setting under Signal’s Waveform File mode, changing this setting doesn’t invoke reloading or reuploading of the file. The selected new file format is used when the file is set next time.
