RE: Transceiver DC01
Witam kolegę z Burzenina :-). Niestety, na spotkanie przyjechałem dość późno i wyjechałem wcześnie, tuż po obiedzie a w dodatku temat bezpośredniej przemiany tego typu w zasadzie dla mnie wtedy nie istniał :-(. Nie potrafie więc zrobić porównania, choć "na oko" tory odbiornika powinny być porównywalne. Moja osobista refleksja wskazuje, że odbiornik ma sporą czułość ale przede wszystkim jest bardzo odporny na modulację skrośną. W zasadzie odstrojenie poza pasmo przenoszenia m.cz (ok. 3kHz) uodpornia odbiornik na silne sygnały o czym mogłem się przekonać pracując równolegle z kolegą, który mocą ok. 100W działał w odległości nie większej niż 1km!. Ten weekend poświęcę na podstawowe pomiary. DDS przerobiłem właśnie na wobulator i spróbuję coś poczytać o pomiarze fazy choć nie mam tej książki o której wspomina Artur :-( Metoda Lissajous to dokładność co najwyżej kilku procent a przy moim oscyloskopie pewnie i więcej. Doczytałem się innego sposobu i choć jest prosty wymaga nieco więcej czasu i przygotowania. W tej metodzie oba porównywalne sygnały należy znormalizować a następnie użyć do bramkowania większej częstotliwości, którą można tak dobrać aby dla przesunięcia fazowego 90 stopni czas otwarcia bramki pozwalał na przejście np. 9000 impulsów. Dałoby to (teoretycznie) dokładność 1/100 stopnia czyli znacznie lepiej niż potrzeba ;-)
