The Spooky2 GX Pro differs from its old version of GX in many ways, the GX uses discrete components to measure current and phase angle, and each of them adds “electrical noise” to the measured signal, the technical term for this is Johnson-Nyquis Special noise (Johnson-Nyquist noise). Johnson-Nyquist noise produces many spikes in GX, from Wikipedia explain: “Johnson-Nyquist noise (thermal noise, Johnson noise, or Nyquist noise) is caused by the internal Electronic noise produced by thermal perturbations of charge carriers (usually electrons), which occur regardless of the applied voltage. Thermal noise is present in all electrical circuits, in sensitive electronic devices such as radio receivers can swamp weak signals and can be the limiting factor in the sensitivity of electrical measuring instruments.”
In simple words, current flowing through any conductor or semiconductor creates electrical noise, and the higher the resistance, the louder the noise. This is unavoidable and not the result of poor quality components, e.g. a 100 ohm resistor will have more noise than a 1 ohm resistor, no matter how the resistor is made. The GX Pro uses multiple fast microprocessors to directly measure current and phase angle. Fewer components and digital signal processing greatly reduces Johnson-Nyquist noise, resulting in smoother GX Pro BFB graphs.
Lastly, Spooky2 guarantees that the Spooky2 software has never had data filtering mechanisms to amend its chart smoothing, and will never.
