Sound Card Signal Averager Toggle
There are two distinct averagers, Waveform and Spectrum. The current display mode determines which averager will be activated via the toolbar Averager button (ALT+A), and which control dialog will open in response to the thin button beneath it (CTRL+A). Below that is a "sunken" box that shows the total frames acquired by the relevant averager.
Once an average has begun, the Averager button changes to 'Wave Avg' or 'Spect Avg' to show which averager is running. If you toggle to the opposite display mode with the Spectrum button (ALT+S), the original averager continues to run, unaffected. This allows you to see the spectrum of a waveform average.
If the spectrum averager is running, toggling to the waveform display will show only the instantaneous waveform input for the spectrum averager; it does not show the inverse spectrum of the spectral average.
Avg=1 starts a Waveform Average if the display is currently in waveform display mode. In Spectrum mode it starts a Spectrum Average. Avg=0 cancels the average, and Avg=x starts an average if none is running, or cancels a running average.
Caution: Be very careful with Avg=0 or Avg=x. If a running average is cancelled, the averaged data is lost and the display reverts to live data. Use Pause=1 to Pause a running average, and Pause=0 to resume the average.
Avg#W=1 starts a Waveform Average from either waveform or Spectrum mode. It is the equivalent of the ALT+\ accelerator key. (There is no option to do the reverse and start a Spectrum Average from waveform mode, since spectral data are not available to be averaged.)
WaitAvg or WaitPause Event Wait Macros may be used to suspend macro processing until an average is done, so the results are available to be saved or otherwise processed.
