A quick measurement performed to provide quantitative data to an old discussion. Same track, same engine, same TIU, same PH180 brick.
Passive mode is with and without gunrunnerjohn's 22uH choke to block out the DCS signal from flowing into the power.
No Choke... Active voltage > Passive voltage.
With Choke... both modes pretty-much the same.
(Read the V pk-to-pk values on right, the waveform is too hard to tell)
Good to know!
