Cursitor Doom <curd@notformail.com>: Jan 14 05:42PM I've now uploaded 3 photos of what I'm seeing. The most obvious noise (apart from being obvious) is the 'comb' across the screen. I'm getting the most spurii at the lowest 'fundamental' (around 5Mhz) but as I sweep up in frequency the number of spurs declines markedly so by 200Mhz there are only 4 spurs remaining and they're much wider apart. The other form of noise I mentioned in an earlier post is the more attenuated and spread out one visible just to the right of the centre-frequency line. This noise, unlike the 'comb' is constantly flickering and random. https://yandex.com/collections/card/5e1dfafd874e97d27c81ef46/ -- No deal? No problem! :-D |

Not to mention ingominous failure! Well, the traces I'm seeing (and have now posted images of to the group) do bear a certain distinct similarity to what you described, Jeff, so if that be the case I'm wondering if one of the oscillators is being over-driven. I'm guessing that might give rise to 3rd harmonic spurii, don't you think? -- No deal? No problem! :-D |
