Siglent SDS1000X-E (4ch)
Siglent SDS2000X-plus
Siglent SDS1000X-HD
Rigol MSO5000

AFAIK...

The cheap Siglents need an external Siggen.

(Siglent, of course..)

It seems you have not been observant ......

Siglent AWG's OTOH are plug and play for Bode plot with all Siglent DSO's that support it.

Maybe you should also mention that Siglent were the first to introduce Bode Plot in late 2017 with the SDS1004X-E series.

And it was (and still is) an ambitious feature, three channels in parallel (so you could trace a three-way crossover network for a speaker system in a single step), up to 120 MHz, AGC, frequency selective detector and consequently more than 100 dB dynamic range.

The competition eventually followed suit, but most of their "me too" implementations are nothing to write home about in comparison.
nctnico:
No, Keysight pioneered bode plotting. Siglent copied it quickly. But according to Rudi's review, bode plot works super slow on Siglent scopes compared to R&S and Keysight (minutes versus tens of seconds). So that is something to consider if you want to adjust something which needs several sweeps (or just want bode plot to work at a reasonable speed). And it is not like the dynamic range on other oscilloscopes is bad. My R&S scope has a dynamic range of around 90dB which is perfectly useable.
