Hi, I've a digital signal which at a certain point stops working (it doesn't change anymore) and I'd like to capture the latest period of time (let's say 10 microsec) until the last edge, in order to see what happened before it stopped. I tried with "repeat" trigger mode but I'm not sure it does wha...

sample rate explanation required

Hi, I just bought a 3206d. I set one only probe, 8bit, one buffer. I also set 100 ms/div, 1GS and I get : 4 ns sample interval, 250MS/s sample rate and 250,000,007 samples in my wave properties. Apart from that 7 that I don't understand clearly but I suppose it's a rounding effect or similar, I expe...
