The problem with RF electronics, is that you can't really get anywhere without a reasonable set of instruments to test/measure.
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. RF spectrum analyzers are very expensive. A very, very skilled RF engineer can get far with cheaper equipment and lots of ingenuity. But such an engineer would not need to ask for help on this forum ;) |
