Figure 55: Frequency editor window after identification
The blue points show identification results.
There are no red points and no point listing in the selection box since all the
frequency points have been run and there has not yet been a new request.
You can add and edit new frequency points and run them; their identification
result will be appended to the existing frequency response results.
For the above identification, the resolution seems poor near the anti resonance
and near the 2-3-4 resonances. We would like to increase the resolution there, and
use the Add>Graphics tool.
Add the red frequency points to the graph; on the next "Run Identification" only
the frequencies you added will be identified, and appended to the existing
identification record.
Notes:
Poor resolution usually reflects in the phase window being clearer than in the
amplitude window.
Do not confuse 360 ° phase jumps with phase resolution problems. Phase jumps
of 360° (see the right end of the above phase plot) come from angle display
folding.
