I'm not bothered by the slow rise/fall times of the SDG10?2X-plus for square waves, so I might get one in the close future.

Based on the results of the 100Mhz sine wave, we can expect faster square wave rise time using Arbs, I'll do this later see how it goes.

Fortunately, Siglent does not limit the bandwidth/rise time of the output stage on SDG1000X PLUS, even on the lowest 25Mhz model :popcorn:

No, The keyboard is good and quite useful, The only complaint for me is that all buttons are a bit heavy, needs more force to press than usual.

IMO, it is more convenient to use the knob when needs to continuously change paras, say frequency and amplitude. also when selecting Arbs or files.

Thanks for your feedback.

I had a short play with SDG1062X Plus on a recent HQ visit and I have some SDG1022X Plus coming in a few weeks when I can investigate your feedback more deeply and maybe pass recommendations to HQ.
For now I'll keep using my SDG6022X.....

Square Arbs.

1Vpp square into 50Ω terminal,
C3 is Ordinary built-in square wave,
C4 is Arb square,

100Hz 11.12ns Vs 5.78ns rise time, more ripple on the faster square wave is expected.


1Mhz, same result


10Mhz, very noticeable ripple on faster square wave.


20Mhz, Arbs are in DDS mode (True Arb can't do it due to the 250M max sample rate)
We get that classic DDS jitter here.


Any higher square wave above 20Mhz is useless on SDG1000X PLUS as limited high frequency content makes it closer to a distorted sine wave.

If you really needs faster edge, the Arb square wave will simply do some help.
Not as exciting as 100Mhz sine wave though. ::)
