Just place the oscilloscope probe, open or connected to a piece of wire to serve as an antenna, close to the primary circuit (possibly several feet away) and observe the waveform when the spark gap fires. The quality factor is essentially equal to the number of oscillation cycles that can be observed before amplitude drops to ~1/20 of the starting value. A good primary would generate many tens of cycles. I am thinking about testing just the primary circuit, with the secondary coil moved away.On Mon, 28 May 2012 20:13:15 -0300 Antonio wrote:An oscilloscope observing just the primary circuit would identify if its quality factor is high enough and if the gap is working correctly. Antonio Carlos M. de QueirozAntonio, How does hook up an oscilloscope and determine the quality factor that you speak of? Thanks, Russell
