I'm back at home. Just calibrated the scope and got some screenshots @ fungus: By zooming, I guess you mean to have the lowest timing per division, am I right? I see rise time oscillating between 2,9 and 3,2 ns on all channels. The more channels I activate, the (much) worse rise times... 5 ns and more with all channels activated? I could gladly take more screenshots if (any of) you have more suggestions Screenshots attached |

FW 1.31 available: Version 1.31 The channel's deskew range are expanded to +/- 1us. |

It would agree with numbers reported by TK in reply #110 https://www.eevblog.com/forum/testgear/possible-gw-instek-gds-1000b-hack/msg2378559/#msg2378559 |
