content: Hello all,Like everyone else, looking for low cost scope, I don't want to spend more than $1000, but will for a good reason. Going through the selection process, I see very little information on the Siglent SDS1000CFL line. What is your guys opinion on this model? I like about it is 4 Ch and 2GS/s. While 4 Ch's is not critical, it is nice to have debugging SPI/I2C.I'll be mostly using it debug digital signals, up to 20-24 MHz, usually much slower. I figure I need at least 100-MHz, 1GS/s min, and >1 MB memory depth. Here is my breakdown so far. I'd love to read your opinions?Rigol DS1000Z - Tempting. Max out at 100-MHz BW, has 1GS/s, 4 Ch's. With 3 or 4 Ch's are active, it's down to 250MS/s; hence, usable BW of about 5-MHz for digital signals. I really see this more as a 2 CH scope.Siglent SDS1202X - Very little information out there. Great review Dave! 200-MHz, 1GS/s, 2 Ch's. Other then 2 Ch's, I see this as a front runner to the DS1000Z to settle on 1GS/s.Rigol DS2000A - 2GS/s, 2 Ch's. If it's really hackable (yea, I'm worried to buy and the hack not working), 300-MHz capability is extremely nice and major plus.Siglent SDS1000CFL - 4 Ch's, 2GS/s, 200-MHz. Low memory depth at 24 kpts. This is probably the limiting factor knocking it off the thrown. Why no reviews? There must be a reason behind the lack of usage.Siglent SDS2000 - Other then pricey, 4 Ch's, 2 GS/s, 100-MHz, seems like a winner if I don't take hackability into account.Instek crossed out as one of the review's showed waveform reproduction errors, if I can't trust the instrument, then it's useless.Agilent DSOX2000 - love it, outta budget. Got to make a sacrifice somewhere.Thank you

content: SDS2000: Would be nice hardware, the firmware is so buggy its close to useless though. Thread here:https://www.eevblog.com/forum/testgear/siglent's-new-product-msosds2000-series/SDS1000: 24k memory, not really useful. Also i doubt the firmware is much better.

content: Hey Mark, I can see that this video is for the older scopes i.e., 2000A series, please check out the GDM2000Eseries, these are Instek's new scopes and they are superb, I paid £960 for my GDM2202E sometime during July'15, I notice now that they have knocked a further 20% off their entire 'E' series scope prices. There's a price war going on right now.In fact, I'm so impressed with my Instek GDM2202E scope that I'm seriously thinking about buying the GDM2204E aswell.
