The "DHO814" configuration has 200MHz real bandwidth and that's the best choice for this hardware. |

--- Quote from: Markus2801A on June 25, 2024, 06:23:59 am ---Also I don`t get it why you only should gently upgrade to DHO814? --- End quote --- I think what people here are trying to tell you is that because the DHO800 AND DHO900 series have 1.25 Gb/s sampling, as you use more channels that sampling rate drops to 312.5 Mb/s at 4 channels, which is not sufficient for accurate 200 MHz BW work. The DHO814 is rated for 100 MHz so is in the 'safe zone' for accurate sampling using 4 channels. Rigol seems to be playing a little game advertising BW because both DHO800 and DHO900 can only accurately sample 200MHz with 2 channels due to 1.25 Gb/s sampling shared across all channels. So if you upgrade DHO804 to DHO900 series and use 4 channels for 200 MHz BW work you may not realize the results are questionable - safer to limit BW to what sampling is capable of. But nothing stops you from upgrading DHO800 to DHO900 for other features if you keep that in mind. The problem is you can easily forget. Siglent has 2 Gb/s sampling, so can more safely use 4 channels for 200 MHz BW work. Of course, not everyone need such high BW to begin with. |

Too bad the Siglent SDS804X HD seems to have a long delivery time and the SDS814X HD costs almost +100€ more. |O So I will have to wait and have more time to rethink my whole purchase decision. Are there any other suitable models out there that I may have overlooked? Kind regards, Markus ;) |

That’s nearly a 25% savings compared to the SDS814X. |
