| Should I replace my Siglent SDS2014X Plus oscilloscope with SDS3014X HD? |

Since I'm not an pro, I prefer not to be misled by the values I see on my measuring device. After all, it's just a "tool" to assist me. I am just looking for better "tool". I have many reason, but isn't only 12 bits reason enough? --- End quote --- Maybe, maybe not. How often do you use the 10-bit mode on your present SDS2000X+? And when you compare it to the 8-bit mode, do you think "gee that's a lot better but I'd be willing to pay a lot more for further improvement"? If so, 12-bit is definitely for you. If you don't use the 10-bit mode or can't tell the difference clearly enough to matter, then 12-bit won't change your life. For me, given the limited resolution of the screen itself (which is the same on both scopes) the place where more bits matters enough for me to care is when I'm using the vertical zoom feature to look at something. Do you use vertical zoom? --- Quote ---I wish I were rich, but I'm not. Nevertheless, I haven't seen anyone become richer or poorer by saving on the price difference we're talking about here. --- End quote --- Perhaps on one instrument, but if you apply that same thinking to the rest of your bench and end up with a few more digits on your DMM, better specs on your AWG, etc etc you might end up with a substantial "investment". |

If I'm thinking of the right thing, it lets you set the start and end times of an interval over which the measurement is computed. --- End quote --- It gets even better: For example, all lecroy scopes have gated meauserements. You set one point, then the other and measurements are taken in between - awesome. Then the old ones had a feature that is no longer available on the Lecroy - but the SDS2000Xplus has it, and that's why we have 6 of them... As mentioned, you can create a gate and measure in it, old Lecroys and the Siglents also allow you to move this defined gate anywhere on the screen... Very useful for (alternating current) load steps... We use it to measure the recovery time, i.e. when the voltage returns to the tolerated range. Therefore: No movable measurement gate, no scope for us. ;) |

Batterfly had it heavily discounted, and now it is not listed at all. --- End quote --- That's right, it's gone and the prices for the 200 and 350Mhz versions have dropped significantly again... so at Batterfly, at Batronix or Welectron you don't see anything. Not yet, I suppose. (picture: all prices without VAT) (Batronix and Welectron still have the 2104X HD on stock, maybe it´s worth asking for a "very special offer"...) |

These advantages make it suitable for applications requiring precise measurements and analysis of signals, especially when dealing with small signal amplitudes or capturing fine details in waveforms. However, I agree with you that for many general-purpose applications, an 8-bit oscilloscope may suffice and be more cost-effective. --- Quote from: bdunham7 on March 17, 2024, 03:29:19 pm ---Perhaps on one instrument, but if you apply that same thinking to the rest of your bench and end up with a few more digits on your DMM, better specs on your AWG, etc etc you might end up with a substantial "investment". --- End quote --- I don't want to focus solely on the financial aspect, but I believe it's important to mention that the device in question would cost me around $1K. To elaborate, I have already sold my Siglent SDS1104X-E for $500 and finalized a $200 deal with a buyer for my Tektronix 2430A, which has only one working channel. Additionally, I intend to sell my SDS2104X Plus for minimum $1,250. Altogether, create total budget of around $2K from these three devices. With the potential tax advantages, I would only need to pay around $1,000... Perhaps the question becomes clearer: "Is it worth investing $1,000 for the new features?" |

I have identified two important points so far: Firstly, device is new, so, I may encounter potential hardware issues. Secondly, I will be deprived of features like LA, which I frequently use, as I cannot hack it for now. This is significant to me because software options are beyond my budget... |
