As I say often to my 5 year old "We lead by example", not by face palming. I find the ongoing trope that Millennials are lazy/entitled/self centered to be incredibly tiresome and really just one step removed from racism (the idea of making oneself feel better by putting others down). I've met lots of 20 year olds who work hard, ask the right questions and spend their days facing challenges that boomers can even imagine. On the flip side I've met plenty of "grown ups" who were anything but. |

Does that mean the mini version is better? Somewhere I read that different manufacturers have different definitions for the max capture rate and memory depth. Am I correct? I am trying to decide among various Micsig models. For Max capture rate, which would be sufficient and recommended? 80K wfm/s, 250K wfm/s or 500K wfm/s For memory depth, which would be sufficient and recommended? 18Mpts, 28Mpts or 90Mpts? Between the two variables, which is more important? --- End quote --- I'd go for the deepest memory. Waveforms/s isn't important when it comes to modern DSOs. They all have enough. Memory depth can be specified in wildly different ways from memory per channel to total memory (which is then divided across the channels). Keysight is the worst when it comes to specifying the memory depth because the actual useful memory depth is 1/4 (or less than 1/8 if you have digitial channels and reference traces on) than what it says in the specification. |

With the upcoming decoding feature, it seems that the Micsig scopes have all the features of the Keysight 1000x, Rigol 1054Z and GW Instek GDS-2204E plus touch screen. Anybody can comment on how they are ranked in terms of GUI? I think the Keysight 1000x scopes have 1Mpts only. For the Micsig scopes, they have 18, 28 and 90 Mpts. Is 18Mpts sufficient? If I go for the 28Mpts ones, I may need to pay twice the price. Somewhere in the forum I read that although the TO1104 has a bandwidth of 100Mhz, it can measure signals of about 250mHz in reality with slight reduction of signal strength. Am I correct? |

Some of you regret not buying the battery with the scope. What is the point for paying extra to get a battery if the scope is used on the bench table all the time? |

Would you trust a wallwart for this use case or prefer complete removal from any external power source ? |
