As we know, Spooky2 Central only accepts a 5volt / 100% offset square wave input. Any other voltage/amplitude or waveform may cause damage.
But in the software version 20190226 and later, many of the Plasma presets are set to 10 volts, with a 0% offset. Why is this?
In fact, the settings are still the same as before. We just change the way the signal is made. Take Spooky Plasma Advanced (P) – JW as an example.
Both outputs are set to 10 volts and 0% offset, but you can see that “Positive Waveform Only” has been selected. This is equivalent to 5 volts with 100% offset. You can see this from the waveform:
The red graph shows the waveform of Out1. The blue graph shows Out2.
So why do we make this change?
As always, we continuously strive to improve Spooky.
Using Spooky Plasma Advanced (P) – JW again as an example:
1. This preset modulates the signal by 1/512th of the fundamental. This is a sub-octave, making it more potent. Out 2 provides 10% gating, so the pulses at the tube are more intense. The energy is sent in shorter bursts.
2. In the old presets, the gating function was realized by continuous commands being sent between the computer and the generator. This is slow, because all commands must go through the same USB port. Now gating is inherent in the waveform, so gating can be much faster and more effective, since the rate of gating matches the signal better.
