SXRTO - Co to jest?
Podstawowy oscyloskop czasu rzeczywistego
Oscyloskopy czasu rzeczywistego (RTO) zostały zaprojektowane z myślą o wystarczająco dużej częstotliwości próbkowania, aby przechwycić w określonej przez urządzenie szerokości pasma analogowego, sygnał przejściowy i niepowtarzalny. Wykryją one impuls o minimalnej szerokości, ale jego zarejestrowany kształt będzie daleki od zadowalającego, nie mówiąc już o jego pomiarach czy charakteryzacji. Typowe oscyloskopy RTO o dużej szerokości pasmai przekraczają częstotliwość próbkowania być może dwukrotnie, osiągając w ten sposób do czterech próbek na cykl lub trzy próbki w impulsie o minimalnej szerokości.
Losowe pobieranie próbek
W przypadku sygnałów bliskich lub przekraczających granicę Nyquista RTO wiele oscyloskopów RTO może przełączyć się na tryb zwany próbkowaniem losowym. W tym trybie oscyloskop zbiera tyle próbek, ile to możliwe dla każdego z wielu zdarzeń wyzwalających, przy czym każde wyzwolenie dostarcza coraz więcej próbek i szczegółów w zrekonstruowanym przebiegu. Krytyczny dla wyrównania tych próbek jest oddzielny i precyzyjny pomiar czasu między każdym wyzwalaniem i następnym występującym zegarem próbki.
Po dużej liczbie zdarzeń wyzwalających oscyloskop ma wystarczającą liczbę próbek, aby wyświetlić przebieg z żądaną rozdzielczością czasową. Nazywa się to efektywną rozdzielczością próbkowania (odwrotnością efektywnej częstotliwości próbkowania), która jest wielokrotnie wyższa niż jest to możliwe w trybie czasu rzeczywistego.
Technika ta opiera się na losowej zależności między zdarzeniami wyzwalającymi a zegarem próbkowania i może być stosowana tylko w przypadku sygnałów powtarzalnych – tych o stosunkowo stabilnym kształcie fali wokół zdarzenia wyzwalającego.
Oscyloskop SXRTO
Maksymalna efektywna częstotliwość próbkowania modeli PicoScope 9400 16 GHz wynosi 2,5 TS/s, przy rozdzielczości taktowania 0,4 ps, czyli 5000 razy wyższej niż rzeczywista częstotliwość próbkowania oscyloskopu.
Przy analogowej szerokości pasma do 16 GHz, te SXRTO wymagałyby częstotliwości próbkowania przekraczającej 32 GS/s, aby spełnić kryterium Nyquista i nieco większej (być może 80 GS/s), aby ujawnić kształty fal i impulsów.
Dzięki losowemu próbkowaniu modele 16 GHz dają nam 156 punktów próbkowania w jednym cyklu przy znamionowej szerokości pasma oscyloskopu lub hojne 55 próbek w przedziale od 10% do 90% jego najszybszego czasu przejścia.
Czy zatem SXRTO jest oscyloskopem samplingowym?
Całe to mówienie o częstotliwościach próbkowania i trybach próbkowania może sugerować, że SXRTO jest rodzajem oscyloskopu samplingowego, ale tak nie jest. Nazwa oscyloskop samplingowy umownie odnosi się do innego rodzaju urządzenia. Oscyloskop samplingowy wykorzystuje programowalny generator opóźnienia do pobierania próbek w regularnych odstępach czasu po każdym zdarzeniu wyzwalającym. Technika ta nazywa się sekwencyjnym próbkowaniem w czasie równoważnym i stanowi zasadę działania oscyloskopów PicoScope z serii 9300. Oscyloskopy te mogą osiągać bardzo wysokie efektywne częstotliwości próbkowania, ale mają dwie główne wady: nie mogą przechwytywać danych przed zdarzeniem wyzwalającym i wymagają osobnego sygnału wyzwalającego – albo ze źródła zewnętrznego, albo z wbudowanego modułu odzyskiwania zegara.
Przygotowaliśmy tabelę pokazującą różnice między typami oscyloskopów wymienionymi na tej stronie. Przykładowe produkty to kompaktowe, 4-kanałowe oscyloskopy PicoScope.
