| Martin72:
I held the probe during testing/saving. |
| KungFuJosh:
I left the probe in a fixed position on its own where I didn't have to touch it. The ground spring gave it enough tension to stay still. |
| Martin72:
I don´t think it has something to do with it. But will repeat the test with fixed probe and with another probe from lecroy. Your amplitude seems higher when comparing the pics. |

This will remove the termination and you should see a voltage rise to approx. 4.8 V about 8 ns after the signal edge (from 0 V to approx. 2.4 V) (screenshot: red signal curve)." I think my pic is pretty spot on, no? Edit: when you do your test again, please move the ref table so we can see the axis numbers. |
