Question 25 of 25
Explain what an active probe is for an oscilloscope, and why they are useful for some measurement applications.
Reveal answerActive oscilloscope probes contain electronic amplifiers within them, the purpose of which I leave you to research!
Follow-up question: can you think of any disadvantages of active probes? In other words, reasons why an old-fashioned passive probe would be a better choice than an active probe for signal measurement?
Notes:One place your students might wish to research in answering this question is a technical specifications page for different oscilloscope probes. By comparing the specs of active versus passive probes, the advantages (and disadvantages) should become evident.
this is so helpful thank you
Veľká vďaka za poučný článok. Ešte keby tam bolo napísané, ako sa vypočítala tá frekvencia 400 Hz, 40 Hz, 6,67 kHz
