That works well for me. --- End quote --- Have a study up on User definable Default, a very useful feature. ;) --- End quote --- I've heard it has lots of customizable buttons and such, haven't gotten that far yet in the manuals. But I like the default button, default. ;) I actually use the auto set and default buttons. They're both useful to me. I don't see the benefit of twiddling first and tuning later. I like to hit auto set and twiddle after. --- Quote from: tautech on August 30, 2018, 01:48:01 am --- --- Quote ---One thing I think is stupid that the Siglent shows in the manual: "Curr means the current memory depth." Why wouldn't they just write Mem? Cur means a crappy dog. Is that what they want their scopes associated with? Crappy dogs? :palm: --- End quote --- Page # ? Please offer a suggested manual edit ? --- End quote --- PDF page 47, listed as page 23 in the document. #8 8. Sampling Rate/ Memory Depth Display the current sampling rate and memory depth. Sa means the current sampling rate and Curr means the current memory depth. Obviously it should say "Mem" for memory depth. Why would it say Curr for the word Current when it isn't measuring current? Does that make any sense? The simples answer is the correct one. Sa, or preferably Sam for sample, and Mem for memory. |

Josh, does copy editing Siglent's manual count as "free debugging?" ;D (You know I had to ask.) |

"Curr" is what appears on the screen, and I agree that "Mem" would be much clearer. --- End quote --- Hmmm, I see both points of view as in Curr as pertaining to Mem depth with the 'current' setting and the same applies to the sampling rate wherein it changes too due to scope settings and/or active channels. Whatever they're called there will be some confusion for a DSO newbie. Curr, Pres, Exist, Mem and so on as each is not a static value. Curr clearly points to 'with current settings'. Interesting point though, maybe it should migrate into the main thread about these scopes so those that have posted there can get a chance to add their 2c. |

Yes, than it might be important. --- End quote --- In those cases "low noise" isn't enough. To make it useful you also need really good DC offset ability, etc. (I suspect this is the real reason the DSOX3000T/DS7000 designers haven't made any special efforts to reduce noise - opamps that can recover at >5Ghz when massively overloaded are difficult to find so there's no point in trying to please the "low noise" market segment) --- Quote from: 2N3055 on August 29, 2018, 10:00:45 pm ---And yes. Hires mode helps a lot. It will also reduce effective sampling frequency for same factor. So you end up with a 5 MHz scope. --- End quote --- Jitter aside, the rise times, etc., will be identical in hires mode so I'm not sure where that number came from. --- Quote from: 2N3055 on August 29, 2018, 10:00:45 pm ---Real low noise and sensitivity with full bandwith cannot be replaced sometimes. --- End quote --- True, but if you really need that then you have to buy a 12-bit 'scope. The bottom bit of a high-speed ADC is always a bit random so an 8-bit ADC leads to approx. 1mV of noise. |
