TuningParam #1 (0.9000) 1 Grid Point from 0.9000 to 0.9000
TuningParam #2 (1.0000) 1 Grid Point from 1.0000 to 1.0000
TuningParam #3 (0.1774) 1 Grid Point from 0.1774 to 0.1774
As the line is printed for each parameter, you can accept the default single grid point (no
search), or enter a desired number of grid search points followed by a span of values within
which to search.
For example, typing:
200 .9 .95
requests that the parameter be searched using 200 evenly spaced grid points lying between
0.9000 ... 0.9500 inclusive.
After you have entered all 3 parameter spans, RVP900 begins searching for the optimum
waveform. Progress messages are printed on the TTY, and the plot updates each time a
better waveform is discovered. Follow the messages to check if the search is converging.
The process normally runs to completion on its own. If the search takes too long, or you
change your mind about which intervals to search, type Q to exit immediately.
When prompted with: Keep this waveform? [Y]:
• Type Y to keep the optimized tuning parameters that were just discovered and
overwrite the starting values.
• Type N to discard the search results and return to the original settings.
