A way for checking F2=1/2π√L2*C2 very quick
« on: July 24, 2019, 02:02:23 AM »
Accessory:
-Capacitor 1uF630V with 2 alligator clip at 2 terminals
-Tesla coil can switches to run on antenna feedback mode
-Oscilloscope, measure by the way get RF signal by 10cm antenna, ground terminal free
Schedule:
-Switches the coil to run in antenna feedback mode
-Make the shunt C1 by capacitor 1uF
-Let the coil run on normal DC bus and burst duration increase gradually to get good signals
The coil run on SSTC mode and RF frequency is f2( include the length of discharge wire on top load) signals is strong, clear easy to measure periods.
Example: 8.5 periods in 10division(5us) so the result is:
10*5/8.5=5.88us
F2=170kHz
