I think the SDS1102X-E can be unlocked for 200 MHz. --- End quote --- No such model has been available in the west only the 2ch 200 MHz SDS1202X-E. --- End quote --- Apparently, I picked up an offer from Hong Kong by mistake. I'm pretty sure they would ship to the US but what's the point? There IS an SDS 1102-X (no E) available in the US at Amazon but there is no point in confusing things: https://www.amazon.com/Siglent-Technologies-SDS1102X-Digital-Oscilloscope/dp/B01410O5D2 The item says it ships from Amazon but since it takes 10 days to get here, I'm not sure where it is actually shipping from. I'm still thinking that the SDS 1104X-E unlocked for 200 MHz is the way to go. In my view, the 4 channel capability is now a requirement whereas in the old days it wasn't even an option. Alas, I won't be in the market for a new scope any time soon. |

There are analog storage oscilloscopes. But this is just semantics. Nobody should consider buying an old analog oscilloscope as their first oscilloscope nowadays. Even the really cheap DSOs offer much more functionality. |

The SDS1202X-E is a far more capable scope. --- Quote ---I'm still thinking that the SDS 1104X-E unlocked for 200 MHz is the way to go. --- End quote --- Certainly, I got a pre-release build that I still have and use frequently today and it still amazes me the capability that's been shoehorned into this fine little package. Both the 2ch and 4ch X-E's sell well here in NZ. |

Not only CAN you do that, I did it repeatedly and successfully. While I like analogue scopes, analogue storage scopes always were a pain in the ass, not least because having a dual beam CRT was advantageous. As soon as digitising scopes became available, people dropped analogue storage scopes as fast as they could. But for quite a few years analogue storage scopes hung on because of the pisspoor speed/resolution of ADCs. |
