I hope before end of next week I can do some lab tests for SDS1102CML and SDS1072CML.
I believe they have latest HW and FW.
I hope Siglent do not update FW and HW very often. SDS1000 series is not anymore newborn baby.
Last time I have only very quick test SDS1072CNL with newest FW version 5.01.02.13.
Not bad.
-----------------------------------------------------
ADD: Here you can find more new freq response test for SDS1072(CML)
BW is clearly improved in new HW. (also Equal Time mode is now lot of better in new FW (+HW))

Next images are from OLD tests using older SDS1072CNL
FW: 3.01.01.31R17
HW: 10-61-3.3
Frequency response -3dB point is (dependent about test setting) between 90 - 100MHz.
ADD: -3dB point is around 115-120MHz in new HW 11-61-3.3Risetime using not so perfect <1ns risetime pulse.
same as before but persistence on (there can see also cursors are auto tracking)
Freguency response using linear sweep from 1MHz to 150MHz
Center is 60MHz and 15MHz/div. In this image -3dB is around 90MHz with this test setting.
(signal from generator using 50ohm coaxial and Tektronix 50ohm terminator in scope input. (this is not ok becouse total load is not 50ohm impedance mainly due to oscilloscope parallel capasitance. But accuracy "enough for this purpose".)
random image
and if some reason do not like black backround....
What is nice, it have
dual timebase. In ALT mode both channel have of course individual separate trig, but also they may have different timebase.
If compare to Rigol DS1000E serie and if I remember all enough Siglent have more features.
(time ago (some year) I have also sold some Rigol DS1000E series and also tested them. With this experience, in this price class Rigol DS1000E was good and when it come to markets there was not so many others. It was first chinese DSO what quality I can accept also for sell to my friends so that I can also meet them later without need later run away.)
Everyone have its own needs and liking and financial situation. This is my personal opinion and NOT related to situation that I sell also Siglents. I'm hobbyist and professional with measurements and electronics and selling is only very little sidecar and not so much business as "get all money you can"... no no and no.
If I get today nearly same price SDS1072CML or SDS1102CML as Rigol DS1052E or DS1102E.
Selection is very very clear and I select Siglent without hesitation. (yes and I have both available as easily)
One I must say, Rigol probes building quality is littlebit better than what Siglent use (these what I have seen. Yes they work and no problem. I littlebit worry this rotary cable connection in scope end - why it is this rotary construction. Fixed is more reliable imho)
Of course there can do many kind of playing, one example with edge ?? trig:
(In this image used dot mode instead of line)
(there is 8ns "jump - no jump" jitter in signal timing, and also then added level jitter. Trigger is some rising edge (left) before display area and trigger mode is of course
edge ?? ))
Some more can find here
http://siglent.freeforums.org/index.phpbut sorry there is finnish language also. (but least some test images may show something more. Later I will continue with some more tests.
