That has a 7" screen. Wouldn't you consider it a huge step backwards?
Sure, I would, if the previous generation had come with 8", yes. -
with 2 GS/s (per chan?). Still if it was 2GS/s shared you'd see a difference in waveform stability when looking at fast signals. Keysight is not in the same instrument class
The keysigth 1000Xs would be my choice if it were not for the (lack of) mem depth. And 2 1/2 channels, how cool is that? -
Siglent says FFT has 1 Mpts, very curious to test it
Interesting can FFT sample rate be altered (up to 1G)? Multiple traces?
In this example I presume 100MSa/s => max 50MHz / 95Hz => 500k FFT bins. So not sure which is correct to call it 1M or 500k FFT? Until now I considered FFT "1M" if it has 1M bins (2M points).
BTW is FFT always limited to 0...XHz + "zoom window" analysis in scopes or some advanced ones allow make actual window like on real SAs? This would make having millions of points much less important. Theoretically should be possible... ?

eh, i understand but i have been always able to get around using very tiny memories.. to me 1 MS is plenty. also, we have yet to see if decoding on this one is really done with full 14 MS or it's limited at 1.4 like it's predecessor. higher samplerate and faster decodes (that i'm sure they are working) are my priority. aside from things that this one doesn't have (sig gen, filter app) the keysight is still more fit to my use
but i'm looking forward to see this new siglent
always exciting to check out new equipment

There was a new separate thread created for the SDS1202X-E oscilloscope yesterday.
Maybe it is better to keep everything under this thread, as this thread was the first thread related to this new oscilloscope from Siglent. -
Even the EDUX1000s' decoders fly, but yes that's ~ $448+$150 kopecks (+taxes?), a bit moar than a Siglent.
And 50 vs. 200 MHz bandwidth, right?
If "fast decoders" vs. "4x the bandwidth" would be the only difference, I'm pretty sure I would opt for the Siglent, even if prices were the same... -

Let's see about that when the first in depth reviews are in. IMHO competing on price instead of quality is a sign of desperation. I think the market for low cost, low quality scopes has been pretty much saturated by the Rigol DS1054Z anyway. It seems there is a lot of interest in scopes which can do more and have fewer (no) bugs. See how many people jumped onto the R&S RTB2004 special offer even though it costs over US $2k.Even the EDUX1000s' decoders fly, but yes that's ~ $448+$150 kopecks (+taxes?), a bit moar than a Siglent.

nctnico, I totally agree with you, however the educational market has a big potential for manufacturers who can deliver lot of features for cheap.
when they need to equip a new test lab it may require 10/20/30 scopes and at that point any saved euro or dollar il GOLD. -

I hear you GeorgeOfTheJungle hope you can get your R&S soon!

Please note that I did say that the Siglent looks good not on a "competing by price" basis, but has a significant performance advantage over the Keysight (namely bandwidth). I agree with you there, to the extent that the price/performance ratio, and the level of performance and quality one needs, should drive the purchase decision; certainly not price alone.
On the other hand, the "bugs" topic is vastly inflated by a few users here. (Yes, I know, GW Instek rules...) And I believe that people bought the R&S because the promo deal looked like an offer you can't refuse, if you happen to be in the market for a scope. Let's see how many people value the R&S quality (nice screen, nice knobs and all) at the regular price, or where the market price eventually settles. -
they claim its a 1MP fft which it is. they never claimed that it is an 1M bins fft

The sds1kx serial decoder bug is very real and a show stopper for me. It's great to buy cheapo if it ~ works better or worse as the 1000z (sluggish, but does the job), but not so great if it doesn't at all as that siglent. I've had to return it even though I still like it very much, fast responsive and a gorgeous display, but sadly not what I was looking for as it can't decode properly. -
Not sure. But easiest solution is to start using this thread again, as it is the oldest.
-

Claim is indeed correct, that means my scope has 2MP FFT, despite being speced as 1MP
But they also list 1GSa/s scopes on Farnell as 250MSa/s so indeed, why not downgrade FFT spec as well

Unfortunately it's not the oldest thread which shows up first in the forum's topic list, but the one with the most recent post... And people who have already posted to the other thread will come back to it because it will show up in their "new replies to your posts" list. So I'm afraid that second thread is here to stay -- we will survive that... -
I have written a remark in the other thread. Maybe this will help

Thanks. Not sure whether this has been discussed before: How does the scope handle SPI decoding (SCL, MISO, MOSI, CS) with just two inputs? -

i would assume scl + miso (or mosi) + timeout

see that UART trigger is 334000 bps max! okay, trigger.. one can get around it
no mention for uart decode max baud rate
besides SPI have a good look at the uart decode, if it can decode 115200 reliably and how high can it be
