And what is meant by "stronger and better FFT capabilities"?
In terms of features, the Siglent FFT function is one of the best.

SDS2000 HD 2M FFT

SDS3000 HD 4M FFT

SDS7000A   32M FFT

and all with only FFT Window: Rectangular, Blackman, Hann, Hamming, Flattop, as we need for sure any better performing FFT Windows  like BH7...

Which scopes are better?
What are you comparing to? Imaginary dream device?

Well, well

may look attached, as you may than understand ... the gear required to go any better on PN & AN measurements.

Picture note: Spectrum from equal samples. Used coherent measurement of ADC & DAC 24/32 bit. Signal at fs/4 where SR is about 40kHz. ENF means enhanced noise floor.

As this forum has a broad user experiences, as from turtles to professionals.

So what is the best, as maximal budget with acceptable performance?

Any professional would do any sheet with list of MUST HAVE and each weighted and also nice to have.

I currently own a WM8600 & SDA6020 LeCroy with nice RIS (200Gs) and Jitter analysis. But those are only 8 bit.
In addition for fast signal checks the SDS2000X Plus as 10bit acquisition is nice.

This means a LeCroy WavePro HD would be the next best as for me Siglent is for away getting into this figures while simple no
performance specification given.

Even the LeCroy WavePro HD now 12 bit but ENOB still not the yellow on the egg. So for may 12 hours of measurement using this xxk$ gear,
no ROI is given so it would be any better to rent it or waiting again 20 years until they get cheap :D.

At the end of the day, using my own weighting list (performance & service & support & long term behavior with Asia), many affordable fails soon out of the list as no value.

you have a Siglent 2104Xplus... me too !
So, I guess that, like me, & thanks to smart guys from the forum, your 2104X+ has beeen converted to a stunning 2504X+ ("stunning" given the price you paid for the 2104X+...) : correct ?

You're completely right!  ;D

thanks to say to me that I'm right, but like most of engineer... I think that I missed a big shity piece of thing somewhere  :-DD
back to subject :
why are you looking for a DSO that has "top-notch" spectrum analyzer features ?
...
On my side : I have a 2104X+ converted to 2504X+ ...
and I can't replace it because vs GSample & BWith, it is a bargain !

then, how to upgrade my scope ?
I found the answer "easily" => get the device that does the job you want !
As simple as that !

To sumup :
- you have a DSO (not cheap !) => cool
- you get a TinySA Ultra (>100Eur) => you have a nice SA
- you get a TinyPFA (70Eur) => you have a wonderfull device ... if it fits your needs...
- you get a LiteVNA (>100Eur) => you have a top-notch VNA

so, if you don't have those last 3 into the list => get them b4 swaping to another DSO (my2 cents)

time related display (oscope), can be usefull
but frequency related display can be more usefull
my 2 cents !...
hope it helps / or feel free to correct if I'm wrong / no brainer :)
