Siglent SDS1000X HD 12bit DSO's
mawyatt:
Rigol rolled their own HS 12bit ADC chip and altho they have a large NRE chip development cost to recover, benefit from a lower recurring chip cost. While Siglent evidently is using a commercially available ADC, they will incur a higher recurring chip cost and these chips are likely the single most expensive item in the BOM.
So seems Siglent chose to use a single ADC and multiplex for each channel to meet their intended cost and market target. Also think the removal of the AWG and using a simpler internal digital interface helps using the external digital probe with active circuitry. The internal AWG in the SDS2000X+ types has limited capability and suspect most serious users utilize an external AWG anyway.
Best,

To be honest,
Buying the rigol MSO5074 was the first time I came in contact with a inbuild awg - Never it comes to my mind having one in a scope.
For me it´s a "solution for very urgent situations", never a decision point or a stopper, when a scope doesn´t have it on board.

Looks awful. Is industry going back to tower style oscilloscopes ?

Instead, least I hope even more vertical height for screen.
Usually also on working table there is more vertical room than horizontal. But there is also other important reasons.
Old times mostly usual oscilloscopes was with 2 channel and even zoom was stacked over main trace with only horizontal zoom.
Now we have least 4 analog channels and propability to use also 16 digital channels all together and splitted window zoom with normal horizontal zoom but also vertical zoom. And even more, serial decodings what also need room on display area so that time correlation with signals can keep.
Measurements instead we can display "where ever", now these use mostly also this very small vertical resources.
Sometimes it feels like everyone just imitates each other and thinking is avoided. Imitate each other even more, then it doesn't matter which manufacturer you get it from.
We need urgently and desperately more vertical height than ever before. When we now see these "wide screen" display in oscilloscopes I think sometimes that maybe thinking has become old-fashioned and thinking is no longer fashionable. Yes I understand it in entertainment displays but why in TM instruments.
One solution is use enough big TFT but also then turn it so that long side is vertical or example 5:4 format or 4:5. My prognose is that this time is coming - or not and then we suffer more and more with these low height wide screens.
When LeCroy did it first time, perhaps time was wrong and the difference felt strange and also others did not follow (least I do not know any one).
Today we do not need display what user can turn 90 degree. It can be fixed so that mechanical construction is not this " fancy " LeCroy but we need more vertical room, desperately and urgently. Who do it now right way first time, I jump right into his/her journey.
