There is another output glitch that I have seen. I sent this directly to Siglent back in early February, but never got a response. It seems like they are much more responsive when it shows up here, so here goes:
When enabling a channel, the DC offset appears to be enabled before the pulse output, and intermittently as well. This can be a big problem when you are starting up. I hope this can be fixed. Generator set at pulse output, low value zero, high value 10V (10Vpp, 5V offset), 3.33% duty cycle, 70 kHz, using Chan 1 out. The generator is driving a 50 ohm load, so one should see a 0-5V pulse.
The first waveform triggers when output is enabled. There are a bunch of glitches, and note the amplitude of 2.5V (equal to the expected offset value into 50 ohms).
The second shows the same over a long time scale, showing that the output looks like the DC offset of 2.5V for almost 70 ms (!) before the signal kicks in. The "black" area to the right of 70 ms is actually a bunch of narrow output pulses (3.3% duty?) at 70 kHz.
The third waveform is just the signal a while after enabling (looks fine).
