content: Perhaps it's a bit premature to ask much about the SDS2000X but I'm sure some of you have some familiarity with it. So my question is if you had to choose one over the other which would it be and why

content: before i even consider to try SIGLENT, the price already is a big turn off. with the money, you are better off buying RIGOL with function gen included --> DS1xxx**editthere are couple of nice reviews hope it helpsbut in the end, i decided not to buy any RIGOL or SIGLENTand it appears there are more bugs in siggy than riggy.

content: The Siglent SDS2000X series is priced very similarly to the Rigol DS2000A series. Or did you mean like get the Rigol DS1074Z-S which would be less money than the Siglent?

content: I already have a Siglent SDG1025 so I'm covered there. I did watch the videos. I really liked the bigger screen of the 2000 series but in the vid, it was observed that the Rigol DS1000 had a brighter screen. The Rigol DS2000 gets rid of those permanent menu items on the left too which has always been a consideration for me to. I'm definitely not against Agilent or R&S but if you were hoping to try and keep the budget under 1k what is one to do. Plus there is the serial decode at a reasonable price. I realize it's not the same performance as an Agilent but....

content: I guess the best advice here is to make a list with functions which are important to you and get an oscilloscope on loan (try before you buy) to test whether it suits your needs.

content: Quote from: mercury on December 09, 2015, 08:01:03 pmI can't say about Siglents but a couple years ago I had a DS1074 and then a DS2072. The DS1074 is A-OK; either it or the 1054 would be a great scope if you need 4 channels. If you don't need 4 channels the DS2072 has several advantages including the larger screen and the menus that can be easily moved out of the way. The Nav knob is also helpful in some respects - but the 1000 and 2000 series are more similar than different. So as nctnico said it comes down to what's most important to you.One thing I don't think I'd make a big distinguishing criteria is the degree of image quality or the intensity grading; while the 1000 and 2000 are different they aren't dramatically different and I'd be surprised if intensity grading is a feature that will make a big difference to you in your work. The TV signals are cool and you should give it a try when you get your scope but I bet most people aren't using these scopes to examine TV signals. If you are heavy into modulation then it should be a consideration but the difference between the 1000 and 2000 really isn't that great; if the amount of difference in intensity grading between the 1000 and 2000 is something you consider significant then you might want to look at an analog scopeIn the following link are some examples of intensity grading - the DS1 looks better than the DS2 and the analog scope looks better than the DS1.https://www.eevblog.com/forum/testgear/first-impressions-and-review-of-the-rigol-ds2072-ds2000-series-dso/msg344028/#msg344028- I think you have to ask - what difference in trouble shooting or decision-making about a DUT would these different renderings cause you to make when using any of the 3?- Disclaimer: these were made a couple years ago when I'd had the Rigols for a few weeks and was just learning my way around; someone with more experience or better skill might be able to get performance from them.As for Rigol as a company, my experience is that they try pretty hard to be responsive. You might not / probably won't get immediate attention to firmware fix or feature requests but I don't think you get that from any of the scope manufacturers. And given all the Rigol users you are in a boat with a lot of people continually surfacing new information and ideas. With either the Rigol 1000 or 2000 you will have probably the best user support system on the planet for an oscilloscope with all the Rigol users in this forum.With the discount at TEquipment.net and the free Bundle the DS2000 is a very good deal. The 1000 series models are also good deals. Plus TEquipment and Rigol seem to work well together - they have good coordination between the distributor and the manufacturer which can avoid or minimize finger pointing.Overall, if you don't need 4 channels and you have the budget the DS2000 series is a good way to fly; if you need 4 channels or you need to keep the budget better in check go for the DS1000 series. You won't go wrong with either.

content: After looking at those 2 year old DS2072 intensity graded images I decided to look at some Amplitude Modulated signals (and one FM) on a MSO2072A. I'm pretty sure it's all the same technology across the time and models but fwiw here are a few images - the only differences are the display settings for WaveIntensity and Brightness. It's subtle and a matter of preference, I think.
