#185622 - that's why.. Responding to: ???'s previous message |
How do you know if a circuit produces disturbance on other frequencies if you can't scan these frequencies with a suitably narrow-banded receiver? A normal oscilloscope will not get you far - it can't do FFT on radio-frequency signals to show overtone spectrum. And even really high-end GHz-capable multi-GS digital scopes who can sample the radio spectra would normally not have the sensitivity for picking up uV signals.
so that's why 500mW to 1 Watt. Thank you Jeckson S Ben |
