The capture routine has to work with any memory size (you can zoom out until you get all the memory, right?) All they need to do is always use all the memory instead of computing a smaller memory size and using only part of it. In reality it should simplify the code. |

When it´s so simple to change, when it seems it got only advantages when always using the full memory amount- Why do a major brand like teledyne lecroy not use it? When it´s so important for many one in the world, why won´t they change it in the last decades, instead they still got satisfied customers around the world..Are these all blind dumbasses ? There must be a advantage when lecory handle it in this way - and a disavantage on the other side. --- Quote from: 2N3055 --- (...) Which (being perfect on entry level products) for some reason is not requirement for big brands like Keysight and R&S and LeCroy. They are allowed to make products that are deliberately limited for marketing purposes. With them it is business decisions and "small niggles". With Siglent and Rigol it's "crap I wouldn't buy"... --- End quote --- True, true... And it´s a very annoying thing. A real superb scope model like the "new" 2K siglent doesn´t have a feature like this zoom out thing - Reading this thread, people who are interesting to buy it may get the impression that this absence is a very bad flaw that would make it unusable. |

More geared towards scientific use. AFAIK Lecroy offers the widest number of signal analysis tools on their scopes (after you pay for all the options). But there are a few things Lecroy doesn't support (on their own designs): peak detect and AFAIK averaging and high resolution are available as (slow) math traces only instead of being produced by the acquisition engine. All in all Lecroy has a very purist approach towards signal acquisition. This is fantastic for signal analysis (I really like my Wavepro 7300A for that) but as a general purpose bench scope it is less than ideal. And calling Lecroy a major brand is a bit of an overstatement; to me they seem to be aiming towards high profit niches. Much of their other gear consists of rebadges. |
