Copy Function
The Copy math function saves a copy of your present waveform in its unprocessed state to the first
available memory location. While processing may continue on the original waveform, the copy enables
faster throughput in some cases by preserving the original data. That is, no calculations need to be
undone on the copy before additional math can be calculated.
This benefit of faster throughput, however, comes at the expense of memory usage.
Follow the ususal steps to set up a math function, selecting Copy from the Misc submenu.
On the Wform Copy right-hand dialog, you can optionally Reset Count or Change BatchSize.
