content: Hello to everyone,Could anyone tells me who of the two oscilloscopes are more "tough" (in the aspect of components quality) and reliable? I know that the Rigol company is subsidiary of the Algilent company and the rigol oscilloscopes are quite reliable of my experience but I have never work a Siglent oscilloscope before. Every opinion is welcome!

Zero.Many, many dozens of units.From my records the DS1k2E has only 1 Mpts memory and only a 5" display.

content: Same here. I have not meet any failure in SDS1000CML/CNL models what I have sold over years.Rigol have small display. 5.6" 320x234CML have 7" 480x234 display. (obsolete model)CML+ have 7" 800x480 also better contrast than CMLCML+ models have also LAN (VXI-11) support.CML/CML+Real hard glass (not glossy) front of TFT.Siglent have separate vertical cotrols for channels. Rigol have shared vertical controls (poor ergonomy)Siglent have full dual time base ALT and dual triggers. Rigol not at all.(separate timebase for both channels and separate trigger settings for both channels in ALT mode.)Digital adjustable filters for both channels separately.7M points extra memory for recorder functions for low speed timebases. With very slow time bases also direct record to USB.(this is not same as normal frame recorder for fast time bases, what is also have) Rigol do not have.Also Siglent Sin(x)/x interpolation keep original true sample points unlike Rigol "fake" Sin(x)/x what is better to name as "smooth" instead of Sinc. (and this Error is also in more new Rigols - unbelievable but true)Rigol DS1000E have never sold by Agilent.Siglent SDS1000 series is also rebranded for Teledyne LeCroy. (yes there was old cases and mistakes/errors with very old FW versions, so if look these "out of box" reviews it need also look how obsolete they are and/or look also if publisher know anything about what he is doing.Siglent make also higher models for Teledyne (LeCroy) (Wave Surfer 3000) and not only oscilloscopes, also signal generators.Teleddyne is not only company who use Siglent. One other example is BK Precision.If one give me free SDS1000CML or CML+ free or Rigol DS1000E. I do not need think one second which one I take. I have also experience with both, long time ago I have sold also Rigol DS1000E series scopes but today I do not want touch them at all.Same if on my table is DS1000Z or SDS1000X and I do not need more than 2 channel. If I need Oscilloscope for serious work and only what I can select is DS1000Z or SDS1000X, I do not even think to use Rigol DS1000Z and this is also based by experience with both. If I reallly need 3 or 4 channel simultaneously and 250MSa/s is enough, only in this case I select DS1000Z if nothing better is available on my table.But then...What is this?:Quote from: 2X
