There is not a single oscilloscope which is perfect for all situations. --- End quote --- Ain’t that the truth! That’s one of the reasons I’ve been leaning towards the Keysight, in that its strengths are very, very different from the LeCroy I already have. It’s a pity the Rohde & Schwartz RTB2 and RTM3 series have such woefully sluggish user interfaces, or else one of those would be a wonderful choice. :/ |

The lack of any mention of waveform update rate kinda scared me off. Do you reckon they’re worth a look? The “portrait” layout of the unit is very appealing. |

Since I already have a heavy-duty analytical scope, I think I should be focused more on a real-time model. Does Siglent have something more like that? |

Consider that providing best WFPS rates vs sampling rates and a digital trigger ? IMO sampling rate is king when combined with a digital trigger. Also consider how sampling rate can be /ch or max/channels in use. Ideally 5 GSa/s (or better) on each channel is the preferred solution. |

You are already limiting choices to scopes with active probe interfaces for some reason. What is the fleet of available probes already? Consider looking at a Siglent 6000A + LPA10 to share probes with the bigger lecroy. --- End quote --- No existing active probes around. Other than appreciating the basic divider ratio detection ring for ordinary probes, the active probe interface isn’t a requirement, just an artifact of the scope class I’ve been looking at. --- End quote --- If its not a hard requirement then better to leave it out, you may well be better served with a lower cost scope to complement the GHz unit already on hand. Given a budget I'm usually putting a third to a half on probing but others have different balances/needs. --- Quote from: tooki on November 06, 2023, 12:53:40 am ---Since Siglent is closely entwined with LeCroy, it’s my understanding that Siglent scopes lean more towards being “analytical” scopes like LeCroys, as opposed to “interactive” or “real-time” scopes like Keysight (and Rigol, which more closely copies them).

Both are very competent for interactive/realtime use. |
