Hello my friends I'm from Argentina, I'm mostly doing chip level repairs, and also some embedded projects. I'm about to buy an oscilloscope. I've been struggling getting an affordable 100mhz 4 channels scope but there's many crappy chinese on the market.
Sadly in my country I can only afford buying the following. Yes I know you may start telling about other brands.. but I can only find the followings
- UNI-T UPO2104CS Supposedly has Ultra phosphor technology but support on the site it's crap no manual no youtube reviews..
- OWON Latest model XDS3104E has a local distributor in my country covering warranty if anything happens. So this is my way to go.
But I would like to ask you what do you think about the following this scope has
an 8-bit ADC , and the advertise as having multi- gradient it's a way of saying they have some ultra phosphor tecnology .
http://owontme.com/products_owon_xds3000-e_series_4ch_12 (http://owontme.com/products_owon_xds3000-e_series_4ch_12)
Also bus decoding its optional on the Owon and on UNI-T it's being implemented although unit is shit
This is what I'm talking about when I mean about intensity gradient

The guy from OWON support answered on email the following
XDS3104E is 8 bit, it is catalogue mistake, please see updated one.
It doesn't need to select intensity grade, if the waveform input the oscilloscope repeat much, it will be intesity grade such as sweep signal.
Waveform record and replay is on page 65 user manual.
Intensity grading is always there, if the signal repeat more, it will appear, if not, it can't see by eyes. Did you use this function before? Thanks,
This is the video the guy sent where he " SUPPOSEDLY" shows this intensity gradient or ultra phosphor , do you guys see the intensity grading ? I don't I just see red solid waveform
