--- Quote from: eV1Te on December 17, 2013, 07:53:59 pm ---I agree that it should look as good as that with one channel also, I just wanted to point out that when you have "too" many points in memory and an unfortunate frequency of the input signal you can get an apparent aliasing on the screen even though you have intensity graded display. But when the difference is that big it must be something else I would think as you pointed out. --- End quote --- Again, look at the chart I posted - the waveform update rate is TRIPLING when using VECTORS instead of DOTS? That shouldn't happen: it should get slower - there is clearly a big bug. |

Here's another @ 500us/div with 1MHz sine wave input. Same settings in both images except for memory depth. Top image is supposed to be 2GSa/s with 14M - bottom image is 200MSa/s with 1.4M. The bottom image is the correct one: |

@JDubU: Did you install the 300MHz option? It would be nice to know if this is connected to that option - or inherent in the firmware in general. |

(I could only test it with 16Mhz, but same at 200µs) --- End quote --- --- Quote from: JDubU on December 17, 2013, 08:44:12 pm ---I am seeing the Dot mode artifacts at 200us/div using the latest firmware with no options installed. --- End quote --- Thanks, Bugware and JDubU. Revamped the BUG LIST on the opening page to reflect just the last two firmware releases (v.01.01.00.02 / v.02.01.00.03) - and added the older AC-coupled Trigger bug (thanks, Teneyes!) and the newly discovered DOTS mode bug. |
