waveform scaling factor
Inverse of the maximum amplitude of the I/Q waveform based on the specified system parameters.
For the frequency modulation schemes (FSK, MSK, and CPM), there is no known analytical method to calculate the maximum amplitude that accounts for effects such as resampling, filtering, and so on. Empirically, a waveform scaling factor of 0.8 should be sufficient for most of your applications. This value results in a maximum dynamic range loss of about 2 dB on third-party (non-NI) RF signal generator devices.
If you receive errors related to this value, your signal might be aliased. For more information about aliasing, refer to MT Modulate CPM or MT Modulate FSK.
