| Siglent SDS1104X-E vs. Rigol DS1054Z Advice? |

| KungFuJosh:
Okay, that all makes lots of sense. I certainly like the idea of the AD2 and all the extra useful features it has for future uses. Besides being better quality, it's more cost-effective than the Siglent addons+required options. Here's the remaining question between the Rigol vs. Siglent: some of you have convinced me that I will end up using 3 or 4 channels at a time eventually. Even if I'm only using 2, the Siglent does support double the sampling ability when running any level of multi-channels. It seems to me like this should be important in my decision making between the two models? |

You won't experience that in the X-E ! |

I'm assuming I'd have to do something fancier to get some screen lag to happen? |

Theoretically you don't need it, 2.5x the bandwidth is enough to perfectly reconstruct a signal (Rigol has exactly 2.5x with all channels on). In practice? I'm not sure how much difference it really makes (screenshots, anybody?) Remember though: You can turn a couple of channels off on the Rigol to get 1GHz sampling when you really need to look closely at a waveform. That makes this a convenience feature on the Siglent not a showstopper for the Rigol. And on that note we're right back to, "The Siglent is 40% more expensive so it ought to be at least 40% better/nicer/whatever than the Rigol". --- Quote from: tautech on August 24, 2018, 07:34:05 pm ---Have you discovered the UI latency in the 54Z ?

(and (b), The Siglent is 40% more expensive, so...) PS: Have we mentioned how much twiddling is needed to enable a simple on-screen measurement on the Siglent? The Rigol has a nice row of buttons down the left hand side for that.

Question: If YOU were running 3 or 4 channels at 100Mhz or better, would you really be satisfied with 250M per channel? I know I'm generally not doing that, but this is a theoretical question. ;) For that particular instance, the sampling is 200% better for only 40% more $$. Same story for the hacked bandwidth potential (not that I care about that personally at this point). I will read that thread though. I obviously intend this to be a more informed decision than my first purchase. |
