but you can't set the corner frequency, and you don't have highpass/bandpass/notch.

Yes, all just as I told in previous message. There is not this kind of user settable FIR filters in SDS1000X-E series. 

In my first answer this first "No." was answer to main question if there is these filters you ask.
(looks like some others also did not even read my answer. Perhaps two many words in whole answer.)


(after then I talk about other thing: Eres, what can use for do some LPF (it is couple of FIR's) but user need calculate or know corner freq with different samplerates and different Eres bit value (0.5 to 3.0 bits))



--- Quote ---I would find digital filters to be useful to look at for example pwm signal. One can use the integrator math operator in conjunction with the offset to produce something that resembles a LPF but the result is rather poor. Same with HPF/Differentiator.
Another is to filter out specific content, BEFORE doing further analysis

If these filters are for just "nice image" or not so serious work they are ok and some times "wanted".
If they are used for real true qualitative and quantitative signal analysis and want trusted data. Then need enough  knowledge about all these filters specifications with data and even data about possible error building mechanisms.


--- Quote ---Is there a plan to add them? I remember reading something about it a long time ago..

--- End quote ---

I have never heard or seen any official promise or forecast. (when we talk about SDS1000X-E series)
(Old SDS1000 models have digital LPF, BPF, HPF, they have even true dual independent timebase ALT with dual trigger engine. These advantages have dropped out from SDS1kX/X-E series.)

Only fact we know, there is not now this kind of filters. (SDS1000X-E series)
Prediction is usually difficult. Forecasting the future is particularly difficult.

It is best to think - food what is now ready in hand, only it can eat.

Of course this and that and even more can add and improve. One want this and other want that and those things - endlessy. If I make product I tell what it is. Buyer think if it pass for him as it is. If not, buyer buy other product what is ok for his needs. Simple. Different products have different pros and cons.

I know least hundred things, or even more, long wish list to Siglent Santaclaus what all I like to get. ;)

Waiting Santaclaus....
maxwell3e10:
Yes, digital filters are useful in a number of situations and in principle easy to implement. Micsig TO1104, Keysight 1000X and Instek GDS-1054B have build-in filter functions. So its a bit of a minus for Siglent.
Rerouter:
To give context, This is what exists in the 1000X-E files, there is also a file "pro_filter_cfg.bin" in the same folder as where the licenses are stored, and in a similar format to those licenses.

CiscERsang:
Hello everyone,

As far as I understood from  In-Depth-Review, SDS1104X-E is younger model than SDS1202X-E. Am I correct?

Thank you!

Yes, correct.
The UI is very very similar with only a few different buttons and a shared vertical control for the 4ch model.

They were released less than 1 year apart.

Study the datasheet and user manual for the differences between the 2 and 4ch X-E models.
