It looks like the LED's that are used for the 1074Z's back-lighting are a bit bluer, but as I said this is not visible "in real life". --- End quote --- Thanks for these. In fact, that bluish-tint is what I see with my eyes, although not as severely as your camera records it. Maybe my vision is slightly weird :) --- Quote ---Funny horizontal lines on the 1074Z's shots. No idea where these come from. They are not influenced by for instance the modulation frequency. The waveform of the 1074Z is indeed a bit more coarse/"blocky". I assume that is because the 1074Z has a lower waveform update rate in combination with a different implementation of intensity grading (Marmad would know). --- End quote --- Those lines (and the coarse/"blocky" look) are caused by math scaling for the display - and this is another one of the drawbacks (cost reduction?) of the DS1000Z which we discussed a bit in an earlier thread (although I can't remember exactly which one at the moment - maybe "Rigol DS1074Z Oscillosope"?). On the DS2000, the ADC values are normally directly mapped 1:2 pixels (200:400px), except when you use the 500uV/div or a vernier setting - those are mathematically scaled. On the DS1000Z, it appears to use math scaling much more regularly at normal scale settings, although I don't think anyone has sat down and figured out exactly when and how often it's doing it (or asked Rigol for the answers). |

Very suspicious :) Notice also that the blue pixels (that form the graticule with to two other colors) show much more dispersion than the other colors (i.e . look more fuzzy) |

It is a great value budget scope and the display is very good for price. --- End quote --- You guys are missing the point, this scope is very good for the price but for a farsighted user the combination of small fonts & low screen pixel sharpness is real deal breaker, something that not only shatter the experience but also leads to further vision worsening. I think that this 3ad could be a usefull warning for people with sight problem that is considering to buy a DS1xxxZ scope. I was just lookink at last great pa3bca shots, "stopped" images fully confirm the fuzziness of pixels edges for DS1xxxZ screen. With not aligned subpixels is impossible to render sharp lines, probably the lcd screen is where Rigol has focused cost reduction. Of course i agree that for normal sighted people the problem simply does not exist, probably leaving place for complaints to a not so fast UI responce. But i'm also sure that a screen like this brings premature eyes aging to everyone. |

I forgot this thread but I went to a trade fair and tried the DS1104Z-S. My first thoughts were like: "What a nice small scope, but what's with that tiny readouts? They are so hard to read." There are some bad fonts. Hameg HMO2000 scopes are easier to read. But the numeric keypad on DS1104Z-S screen is nice (as seen on photos). I did not know about that before. |

The fonts in the menu are OK. |
