To test a chaotic‑power device I’d start with a clean bench. First, isolate the unit with an EMI filter and a Faraday cage to keep stray emissions down. Measure input entropy – you can feed it a true‑random source like a noise diode – and record the output power with a calibrated wattmeter. Efficiency is just output power over the entropy source’s equivalent energy budget, so you’ll need to quantify the entropy rate in joules per bit. Next, run a series of stress tests: ramp the input entropy up and down, cycle temperature from −20°C to +60°C, and monitor output stability. For safety, check for over‑voltage spikes on the output, ensure all high‑current paths have adequate fusing, and perform a dielectric breakdown test on the casing. Finally, run a full electromagnetic compliance check, measuring radiated emissions with a spectrum analyzer, and confirm that the device doesn’t exceed IEC limits. Document every reading, compare against a reference generator, and if all numbers stay within spec and no fault conditions arise, you can claim the chaotic generator is both efficient and safe.

Good point. First, I’d verify the diode’s spectral density over the band I need—measure it with an RF spectrum analyzer, compare the noise floor to the target entropy bandwidth, and make sure it’s flat. If the diode’s output is weak, I’ll swap to a higher‑temperature super‑junction diode or use a post‑amplifier with a very low noise figure. Regarding the cage, I’d perform a double‑tied‑off test: put a calibrated probe inside, then drive the generator, and watch for any leakage at the cage seams. The cage should attenuate external RF by at least 60 dB; if it doesn’t, I’ll add more shielding or redesign the enclosure. Running the device on a treadmill while spinning a top is an excellent mechanical load test—just record the output power with a precision oscilloscope and plot it against the top’s RPM. If the output follows the spin frequency or stays flat, the generator is robust; if it drops when the load varies, that’s a sign of instability. Always keep a log of temperature, load, and output so I can correlate any drift to mechanical agitation.

Got it, I’ll keep the temperature logs tight and the cage sealed. If the output ever glitches, I’ll check the diode bias first, then the enclosure. Stay on target and the chaos will stay in the lab, not in the air.
