content: A comedy of circumstances has landed a GE Instek GDS-1054B and Siglent SDS1104X in my shop. My day job is high voltage protective relay technician. I also do a lot of PLC controls, etc at the day job. In my personal shop I have PLC automated dust collection, large cnc router, co2 laser and other fun things. I like to make and create and automate.My last oscilloscope was a Tek 200Mhz 20 years ago. I bought the Instek last week after liking what I read about it. More reading brought the Siglent. I get the specs and obvious differences.What I’m asking for here is advice, pointers on how to evaluate which of the two I want to keep. My current project is capturing servo positioning error on my cnc router while I tune the servos. I tinker with lots of stuff and have decided I want an oscilloscope in the shop.I appreciate your input!Thank you!

content: I'm happy to report theVonets wifi bridgeworks seamlessly with The SDS1104X-E's built in webserver!The remote control through the web browser is already really appealing. Very cool feature.

content: Do you do anything that requires FRA/Bode plots ?What signal sources do you have to provide the swept sine wave for FRA ?An example:https://www.eevblog.com/forum/testgear/siglent-sds1204x-e-released-for-domestic-markets-in-china/msg1435854/#msg1435854This thread might be of interest if you haven't got/can't afford a Siglent ARB or already have something else:https://www.eevblog.com/forum/testgear/siglent-sds1104x-e-and-sds1204x-e-bode-plot-with-non-siglent-awg/

content: Each of these scopes have features the other one doesn't have so based on specs alone it really depends on what you need. I can imagine input filtering on the GDS1054B can be helpful to eliminate unwanted frequencies from a signal. For example to show a PWM wave from a motor drive as the resulting waveform by filtering the PWM frequency away.If the features don't make a difference for your usage then the best advice I can give is to keep the one which you find the easiest and most convenient to use.May I throw another oscilloscope in the mix? MicSig has the TO1104 tablet (touch screen) scope which is in the same price range. The advantage is that it can run from a battery and it is easier to bring along due to the tablet form factor. The T1104 has the unique feature that you can record videos from the screen so you can replay what has been on screen later.

content: @slodat, did you try both scopes? If so, what did you try and what did you think?

content: Siglent2 ADC so you have 2 channel full 1GSa/s both 14M, and all channels on 500MSa/s 7M each.Always in background running history history, max up to 80000 previous waveforms (acquisitions). Stop and look what just previously happen.Fast segmented acquisition up to 80000 segments and speed up to well over 400000 segment/s (named as sequence acquisition. (for 2 or 4 channel simultaneously up to 109M samples memory in waveform history buffer or segmented)Serial decode with 2 independent decoder with full current memory length decoding, also history and segmented memory can decode afterwards.
