Badania obwodów rezonansowych analizatorem NanoVNA

Od pewnego czasu zastanawiałem się jak szerzej wykorzystać mój wektorowy analizator NanoVNA V 2_2 niż pomiary anten czy filtrów.

Pierwsza rzecz, która przyszła mi do głowy do pomiary pojemności i indukcyjności. Pomiar analizatorem ma istotną przewagę od pomiarów miernikami RLC, ponieważ możemy zbadać parametry elementu w zakresie częstotliwości na których ma on pracować. Mierniki RLC dają tu pewien wybór, ale zwykle kończy się zakres na kilkuset kilohercach. Np. LC-200A mierzy indukcyjności kilku mikrohenrów na częstotliwościach 500 - 650 KHz, co jest znacznie poniżej częstotliwości pracy urządzeń krótkofalarskich.

Drugi temat to badanie obwodów rezonansowych. Kiedyś używało się do tego Grid / gate dip metry czyli generatory z cewką na wierzchu obudowy, którą sprzęgało się z badanym obwodem. Gdy dostroiliśmy częstotliwość do rezonansu, część energii była pobierana przez badany obwód co widać było w postaci spadku napięcia na siatce lampy lub bramce feta i można było ze skali odczytać częstotliwość rezonansu badanego obwodu. Słabą stroną tych mierników był wpływ badanego obwodu na częstotliwość generatora, ale na podłączonym liczniku częstotliwości można było odczytać dokładną częstotliwość.

Postanowiłem spróbować wykorzystać VNA w podobny sposób.

Tyle na wstępie, a teraz do rzeczy.
