These graphs show the Random Frequency Generator feeding a QSC power amplifier and driving the capacitor plates.

QSC output%2C 10 v%2Fdiv%2C 10 VRMS

This is the Random Frequency Generator driving a QSC 1400 power amplifier at an output of 10 volts RMS.  The display is 10 volts per division.

QSC output%2C 10 v%2Fdiv%2C 10 VRMS%2C spectrum 200 Hz

 This shows the spectral output of the QSC amplifier at 10 volts RMS with a marker at 200 Hz.

QSC output%2C 10 v%2Fdiv%2C 10 VRMS%2C spectrum 10 KHz

 This shows the spectral output of the QSC amplifier at 10 volts RMS with a marker at 10 KHz.

QSC output%2C 10 VRMS%2C HV at plate%2C 1KV%2Fdiv

 This shows the Random Frequency output at the capacitor plates.  A 10 volt RMS signal from the QSC amplifier produces 1000 volts RMS at the plates.  The scale is 1 KV per division.  Notice occasional peaks of over 2,000 volts.

QSC output%2C 10 VRMS%2C HV at plate%2C spectrum 200 Hz

This is a spectral display of the voltage on the capacitor plates.  Notice the relatively flat frequency response above 200 Hz.  The fast rolloff below 200 Hz is on purpose to protect the high voltage step up transformer.

QSC output%2C 10 VRMS%2C HV at plate%2C spectrum 5 KHz 

This is the spectral display with a marker at 5 KHz.  The peak is the resonance of the high voltage step up transformer.  The highest known active frequency is 2500 Hz and the system is quite flat over that region.

QSC output%2C 30 VRMS%2C HV at plate%2C 2 KV%2Fdiv

This shows the voltage on the capacitor plates with a 30 volt RMS output from the QSC amplifier.  The scale is 2 KV per division.  Some peaks are over 6,000 volts.  With two active plates driven out of phase, that would result in 12,000 volts between plates.
