Some folks seem to expect a fully fledged 500MHz DSO for dirt cheap. But the SDS2000X+ is just going to be an affordably priced 2000 series top entry level DSO/MSO. At 500MHz, we are entering midrange territory.
What do the 2000 series of other (“A-brand”) manufacturers offer?
I only list Keysight DSO-X 2000 and R&S RTB 2000, because LeCroy doesn’t have anything in this class.
• Max. Bandwidth: Keysight 200MHz, R&S 300MHz
• Max. Sample Rate: Keysight 2GSa/s, R&S 2.5GSa/s
• Max. Memory: Keysight 1Mpts/ch, R&S 10Mpts/ch (160Mpts option)
• Display: Keysight 8.5” non-touch, R&S 10” touch
• FFT: Keysight 64kpts, R&S 128kpts
Granted, R&S has the big advantage of the 10bit ADC here, but does the Siglent SDS2000X+ really look bad when it has
350MHz bandwidth with a
500MHz option for half channel mode, 2GSa/s, 100Mpts/ch standard, 10” touchscreen, 2Mpts FFT and many features as standard that are paid options for the “A-brands”?
Keysight offers 70, 100 and 200MHz models, R&S has 70, 100, 200 and 300MHz models. There are quite some below 200MHz, right?
Siglent of all companies have too many variants? They offer only 200MHz for the bottom end SDS1202X-E, only 100 and 200MHz for the entry level SDS1004X-E, only 200 and 350MHz for the SDS2002X-E (a bridge device to the 2000 series for analog engineers, who want bandwidth at a low price and don’t need more than two channels) – and right now we do not even know what bandwidth variations of the SDS2000X+ we’ll actually get!
The shared controls are a problem for the Siglent 2000+, but not R&S and LeCroy?
I agree that it can be confusing, that there are some long obsolete DSOs still listed. The obvious reason is that there is still a demand for them in some countries.
Anyway, it should be quite obvious that the SDS2000X+ is not going to be a fully fledged 500MHz DSO. But for people who only need that bandwidth occasionally and can make do with half the channels in these situations, this might be an attractive offer.
Can you check total mem depth in History mode when in Decode ?
No matter whether it’s decoding or not, history is always close to the total memory size, i.e. 180~200Mpts per channel pair.
