content: Does anybody have any experience or hands on this scope?From the spec it looks for me very promising, as input is rated to 20V/div (with standard 1:10 probe I coud measure 230V).Is it clone of Atten with better display or …?

content: I had a look at the UTD2102CEX while in Shanghai, a couple of months ago. Powered it up, but had no function generator close-by to test it properly. The screen was quite impressive. No push function on the rotary encoders though, except for the multi-purpose one.As far as I understood, these are the entry level scopes in the UNI-T range.I don't think they are rebadged, but probably made in-house.

content: Well, no menu on/off button, no Single button, multiplexed knobs... This has the same disadvantages as Rigol DS1000 series.

content: I have the UNI-T UTD2052CEL 50MHz 1GS/s scopeThe CEX model looks exactly the same except it has a white front and grey back whereas mine (the CEL) has a greyish/black face and a red back case.I don't know where you got the max 20V/division spec from but mine has a maximum of 200V/div. Maybe that's another difference between these two models or maybe a misprint? Mine for sure has 200V/div. I've connected it directly to mains (120V rms here, USA) with no problems.I could do a review if there is any interest in it.I like the scope a lot it does everything I need but I'm just a hobbyist. In my opinion it's a good scope for the price.Edit:I see the specs for the CEX model is:Time-based range of 2ns/div-50s/divVertical sensitivity of 1mV/div - 20V/divon mine (the CEL) it'sTime-based range of 2ns/div-50s/divVertical sensitivity of 50mV/div - 200V/div10mV/div - 20mV/div in bandwidth limited modeI wonder if the CEX is bandwidth limited below 20mV/div like the CEL is?

content: Quote from: experimentalist on September 26, 2013, 05:51:01 amThat is a bit strange. Most scopes have 5mV/div at full bandwidth. Or better.Rigol DS2000 has 0.5mV/div.

content: The UNI-T UTD2052CEL 50MHz 1GS/s scope has a vertical sensitivity of between 1mV and 20V/div.http://www.uni-trend.com/UTD2052CEl.html

content: I’m wondering what is quality of displayed traces too.“Former” cheap DSO (Rigol 1052 as well) uses 320x240, what for me is hard to accept.Looking for UDT2052CEx (800x480) or 2052CEL I see vertical resolution is doubled.I heard (couldn’t confirm) that quality of displayed traces is poor due to just simple vertical doubling. Not really new signal processing just simple magnification.As I can’t do a side by side comparison could anybody confirm/negate doubling line of traces?Experimentalist could you share your opinion?

content: My siglent is 7" and 480x324 so don't complain. Also, the lowest setting I can get to is 20mv, with bandwidth limited.

content: Only 20mV??? That's weird. Well, that cheap, old and simple Rigol ds1052e had 2mV/div.

content: Haha sorry. Just noticed it was on x10 probe attenuation. It will go down to 2mv on x1.
