2. The triangular wave at around 57khz



3. The triangular wave (yellow) fed into an OpAmp (green), and using the math to have CH1 - CH2 (blue).



4: The ring (not the movie…)


Attachment 5: Measuring the frequency at this magnification, the 400uH calculates to be 370uH. 


Attachment 6: Zoom in more.  (Showing you 6022BE’s smaller division) With smaller t/div the measured frequency is more accurate.  This time, the 400uH is calculated to be 385uH.



7. See the LM2577’s output pin:  The LM2577 is set to max at just around 23-27Volt.


8. A closer look into just one cycle of the LM2577’s output.


9. This is a vertical+horizontal cursor.  The machine supports 3 types of cursor: Vertical, horizontal, or H+V.  (Note also: when zooming in, the display shows the capture rate IF you run it at that time/div BUT NOT the actual time/div when the data was captured.)  With the close zoom, I saw that there was only 1 single data point during the rise!  Including the data point before and after, the whole rise took 3 data points only.  So an even closer inspection was done later.  When including the before/after data point, the measurement (141ns) is an “upper bound”.


10. For a better measurement of the rise time, switch to the highest capture rate.
