content: I've seen comparisons before with other models and it seems the Rigol is often recommended. However, it's been some time since Siglent has time to develop and wonder what the current status is.Rigol DS1054Z: $399Siglent SDS1052DL+: $279There's a significant difference in price, but how reliable are Siglents?My purpose: Typical hobby scope-Max frequency up to 1MHz maybe-Must have FFT-No need for saving signals/printing them-Must be able to represent signals accurately at all time ranges (if you know what I mean, not like 3 points/cycle or something)Thanks

content: Settled, bit the bullet and got the DS154Zafter reviewing the specs and consensus, there's no reason not to get it.

Also, usually a scope with "auto" memory settings will reduce the acquisition memory to about 10x the screen size, to keep the waveform rate high. also slower timebases will use slower sample rates.After using it i can find many reasons not to recommend it, despite the consensus. but i'm a lone wolf, you have to decide if you ever play with better toys

content: 4 channels is double than 2, In todays i2c spi word, 4 channels make a difference, but sigilent is a nice scope for the price, same as rigol. Rigol have the advantage that is very easy to crack and will enable all options for free.

content: So do you all recommend SDS1102CML+ over the Rigol? It's $40 difference from what I can tell.. and fewer bugs with the Rigol?

content: I'm happy with my SDS1102CML, it does what I need, I don't do any complex or super high speed stuff, and I have a separate logic analyzer (just a cheap one) to monitor multiple digital lines.

content: It's $40 difference$40 is nothing, get what you want, I don't think there's much chance of this price range of scopes increasing any in the next few months.I'm quite happy with the 2 ch cml+, good screen, low noise, fast UI, but I couldn't recommend it while it seems to have long(2MB) memory problems.

content: I will say I got my Siglent for WAY under MSRP, so it was a lot more than a $40 difference. In fact I used the difference to pick up an HP E3610A power supply. I'm sure I could have found a similar deal on the Rigol had I looked. Also mine is the non + model, I don't think it has memory issues. At least, none that have affected my use thus far.
