I do wish though he would answer the 200MHz/5ns jitter question for his Rigol.
I actually have an answer for your question: its in the datasheet!
Look at page 3 of the datasheet for the DG1022.
It states that the jitter for non-sinusoidal waveforms is 6 ns! So we are actually better than the jitter for the Rigol 1022G instrument, which has a retail of $250-$300 with a maximum sine frequency of 20 MHz, and a 100 MS/s sample rate @ 14 bits of vertical resolution.
The DG1022Z has an RMS jitter of 200 PS, and it costs $300-$360 with a maximum sine frequency of 25 MHz, a 200 MS/s sample rate, and a 14 bit vertical resolution.
For reference, our generator has a 60 MHz (90 with bluepill, if I remember correctly) maximum sine frequency, a 250 MS/s sample rate, 14 bit vertical resolution, and 4 ns jitter, and with upgrades it only costs ~$150.
That makes it better than Rigol's lowest cost generator on a performance per dollar level, and competitive with their mid range generators in terms of specs while significantly beating the price point.
I am certainly no longer worried about the jitter, as it appears to be a feature consistent with other generators in its class, and comes with a greatly reduced price point.
EDIT: Just as a comparison, the siglent generators are as follows:
SDG830 has 500 ps jitter, 30 MHz max sine freq, 14 bit vertical resolution, and 125 MS/s for $330
SDG1050 claims 40 ps jitter @ 25 MHz in the datasheet (I dont believe that, because the jitter is 8 ns for pulses), 25 MHz max sine freq, 14 bit vertical resolution, and 125 MS/s for $509
Still winning against Rigol & Siglent.
