--- Quote from: the Chris on November 15, 2023, 06:10:05 am ---Yes, I did not expect to see this kind of overshoot on a scope with 50MHz bandwidth. For reference, this is the same pulser on the EXR104 I am using at work. This time without inline terminator in native 50R mode. --- End quote --- Now you get to ask yourself why there is preshoot. :) |

(Fastest update rate would be 1 datapoint per sweep.) |

--- Quote from: Electro Fan on January 15, 2015, 09:14:19 pm ---- kind of curious to see what is the lowest price device is that can produce a really good looking square wave at 1, 5, 10, 20, and 30 MHz? --- End quote --- A candidate for “lowest price” (~$150 scope with AWG). 50MHz from the built-in AWG of the DSO2000. AWF with coax and 50Ω LR. |
