Siglent SDG1032X sine distortion at 1 kHz ?

[rf-loop]

In this topic
https://www.eevblog.com/forum/testgear/comparison-between-siglent-sdg1000x-and-2000x/

there was also some discussion related to this.

Because this topic here now is just named for SDG1032X (SDG1000X series) I think this is good/better place also for this table:



There is also one mystery.
Siglent have changed SDG1000X  10Hz - 20kHz 0dBm sinewave THD % specification.
It have been in old datasheet max 0.075% and in 2022 published latest data sheet (SDG1000X_DataSheet_DS0201X_E01I.pdf) it is max 0.15%

Please, who ever publish somehow trusted way measured SDG1000X  THD please inform also generator HW version (first two digits is enough).  Least I am curious to see if there is real change in latest version. Previous and long time produced HW version was: 02-......   and 2022 started new HW version is 03-.......   and 2022 also datasheet have changed.
