The Toro PowerJet F700 corded electric leafblower is an amazing machine in every way except for its speed control. The speeds seem too close together. Today I measured them by recording each speed for a few seconds.

Viewing the spectrum shows the fundamental for each step, along with some harmonics:

By pressing Ctrl to activate the crosshair cursor, the 1X, 2X, 3X,... pattern of the harmonics confirms than the bottom one really is the fundamental. Next, zoom in to the fundamental to allow a more accururate measurement:

After zooming, it's easy to get an accurate RPM measurement:
measured RPM:
1380
1505
1546
1611
1732

This confirms what I already knew. the speeds are fast, very fast, super fast, ultra fast and howling fast. There are no slow settings.
