Are you blind man?  8)

 :wtf:  A few minutes ago you were calling another member "dishonest", now you come to a 1-year old thread to call another one "blind"?

Why don't you go play with your non-toy KS and stop calling names to other members?  Or did the playground close for the weekend?  |O

--- Quote from: 2N3055 on February 13, 2019, 10:23:31 am ---With my apologies to Daniel and Keysight , I personally wouldn't recommend any of their scopes less than 3000 series.
3000 series is amazingly fast, both in user responsiveness and in retrigger time and is pleasure to use.
It also has very short memory, and as such is not good for lots of decoding, or looking at long captures.
But as interactive scope is the best.

I agree that interactivity and snappiness are the strongest point of the KS scopes, and that low memory are there weakest point (do not argue with that).


--- Quote from: 2N3055 on February 13, 2019, 10:23:31 am ---On the other hand, what is pretty much a single flaw with 3000T (short sample memory) is many times worse with 1000X and 2000 series,

--- End quote ---

I think you exaggerate way too much.

Fact: The new KS budget 1200-series has exactly half the memory of your, many times more expensive, 3000-series scope.


--- Quote from: 2N3055 on February 13, 2019, 10:23:31 am ---and also waveform capture rate is much slower on 1000x/2000 (which was one of good things with 3000). So you get worst of the both worlds.

If you are looking at 1000X series class, from A manufacturer you have RTB2000 that will give you 20x the scope in every regard,but for more money, or you can look at the GW Instek MSO/MDO/GDS-2000E that are fantastic scopes, and also Siglent 1000X-E or even Rigol MSO5000 series (still really new, but will be stable in coming months) for much less money and much better capabilities.

I agree that waveform update rate is a really important factor to miss less information. The KS 3000-series is absolutely fantastic with it's 1 million updates/sec, but it is way to expensive for me.

How do the other scopes which you recommend perform?

The RS&S 2000-series (which I really like and consider buying myself); up to 50 000 waveforms/s.

Siglent 1000X-E; Waveform capture rate up to 100,000 wfm/s (normal mode)

GDS-2000E Series; Waveform Update Rate of 120,000 wfm/s

KS DSO-1200-series; 200,000 waveforms/sec

The only one beating them all is the new Rigol 5000-series (with up to 500 000 wfm/s, with some debates)

I am not sure the Keysight 1000X series has list display for serial decoding, are you referring to 2000 / 3000 series?

--- End quote ---
I don't know about the 1000X series. I'd assume a scope with decoding has a list display...

--- End quote ---
Not the Keysight 1000X series, and micsig added it in the latest firmware

--- End quote ---

I have yet not tested the serial decoding myself, but from the manual and fact sheet for the 1200-series it has pictures at least of a list display in the serial decoding.

My post is 1.5 years old.  Now KS 1200X series serial decoding includes list display

And then there was this non-sense with the screen and dead pixels... Now don't get me wrong. All of that is acceptable or expected if you are trying to build something as cheap as possible. But building something like that, in china, and then asking 3 times the price over something else of similar build quality does not sit well with me.

What caps do you have in Rigol och Siglents?

The fan of the 1202G I have tested is quite quiet (compared to other scopes and measurement/lab equipment)!

If you measure the dB of yours we can compare with mine? Perhaps you can get it exchanged if yours louder than normal/other KS scopes.

What is your serial number (might be dependent if it was an early or first batch version)?

If you do want to give it in public, you can leave out the last digit (or you can PM me if you prefer, and we can compare with the one I test)?

How many dB is it compared to the same type of scopes from Siglent or Rigol?
