I might do that too, although the SDS1000X-HD is much more appealing. The problem is the price, we only know the chinese prices, and I'm afraid we might see a 1199 tag plus VAT once it arrives to Europe. I don't do anything in the digital domain other than the occasional protocol decode or signal integrity check, and I can always buy a Siglent AWG later on. But yeah, the price is the great unknown. |

Or maybe Rigol decides to make this available as an option, for better differentiation vs. the DHO800? Or the 50 Ohm inputs remain unusable forever, which would not be a catastrophe at 200 MHz max. bandwidth. --- End quote --- 50 Ohm is mostly there to avoid reflections in the line. I don't think there will be much difference between internal/external 50 Ohm at that bandwidth. Aside: I wonder how high the bandwidth can go on the DHO1000 series? The DHO4000 goes to 800MHz. We need to see some hacking of these... :-) |

The DHO4000 goes to 800MHz. :) --- End quote --- That's why I said that it wouldn't be a catastrophe to make do without the internal termination up to 200 MHz. (But it would be nice not to have to search for the 50 Ohm pass-through terminator, and not to bump into it all the time when it is installed.) Dave's teardown of the DHO1000 and 4000 suggested that they have the exact same frontend. But since the license protection of the 1000/4000 seems structured similar to the 800/900 series, all 4000-only features may be out of reach for hackers of the DHO1000. I don't think it is realistic to make the DHO1000 believe that it's a 4000; there's an ADC missing... So I am buying this assuming I will get a 200 MHz scope, not more. |

The frontend is quite similar, and has the 50 Ohms input, but it's not identical. In the upper right part of each input channel there are a few components arranged in a different way, just next to the frontend chip. Edit: the pcb looks slightly different in that area too. Maybe it is just due to the manufacturing date, and current DHO4000 is the same. |

Hm, or exactly because they didn't offer any 1000s for a year.... --- End quote --- Batronix unfortunately can't match Rigol's Black Friday discount on the DHO1074. --- End quote --- The Black Friday promotion runs from 24.11. to 30.11. I would take another look tomorrow, keyword best price |
