content: In the market for a Digital Scope and I would appreciate you input.Will be using for Audio Equipment Modding, Repair Work and Analog Synth Repair, Building and power supply Mods and some Prototyping work.Here we go.Hantek DSO4202CPros*Cheapest of the bunch.*200Mhz out of the box.*Inbuilt Signal Function Generator.Cons*Only 2 Channels, but that may be enough for my needs. I don’t know yet I may need 4 channels later.*Hantek doesn’t have the most stellar reputation around here. Have they sorted out out the bugs yet?*Limited Memory Depth compared to others. Does that matter to me? I am not sure?Siglent SDS1204X-EPros*200Mhz Out of the box*4 Channels*Option for logic analyser.*Really Nice looking screen.*Good amount of Memory Depth.Cons*More Expensive.*No inbuilt Function Generator.*At this price point I might as well start looking a the Rigol MSO-5074.Rigol MSO-5074Pros*Everything and the Kitchen Current Sink.Cons*Still pretty new on the market not as stable as the others.*Only good value for money if you hack the firmware. Will I void my warranty?

content: I thought the extra thread would make things less complex these are to seperate questions. The first one is about bandwidth needed to measure opamp oscillation with no particular oscilloscope in mind where this one is about making a choice between a few different makes and models at least that’s what intended.My apologies if I have done something wrong. I still haven’t got a clear answer to my original question.

I realise you started this separate thread in order to add a poll, but see my comment below.You won't get a clear answer:there is no clear answer; personal preference and other factors are importantin my opinion, you have a bad starting point and so the answers are likely to be "wrong"Hence my opinion is that a simple poll is not the best route for you.

content: My 0.02$: if this is audio work and you plan to stick to it I'd rather have two additional channels than additional BW...

content: As all the items you mentioned are relatively low frequency and analogue - you didn't mention any specific digital intentions, you might want to look at something with more than 8-bit resolution and lower noise. Maybe check out the Picoscope range, they're all USB but there are models up the 16-bit (at a cost).Other than that, there are a few 10-bit bench scopes out there. Don't forget USB soundcard (with appropriate input attenuators) options too.

content: Digital Intentions are old analog synths and some newer ones. I would like to improve the SMPS of some pieces of equipment. Adding Inductors using Pre Regulators on a seperate Perfboard.No really keen on a USB scope I would rather a Benchtop Model.
