(b): Can not find a way to do that with manual trigger, I can put both channel in manually triggered mode, but the trigger button will only work for the currently selected channel.
However it's easy to do when using the external trigger.
(c): Certainly <1.75 ns for a DG821pro hacked to the full 200 MHz, measured with a hacked >500 MHz DHO1074 as a upper bound. But there is a firmware bug causing the output can be scrambled when generating continuous slow (<1Hz) square waves like you described.
Given DG8xx pro and 9xx pro are based on a quite new platform, I would expect they will have a relatively long service life and firmware support life. Unfortunately, currently the firmware is in a usable but far from perfect state.

If you read OP question he needs to be able to control rise/fall times. You cannot do that with squarewave, hence pulse signal.
So no that AWG cannot. Sad part is that old DG1062Z can.

Then they should open source it...

It doesn't work that way..
I bought a device that is, say, AWG. It is a device that provides function. FW and HW is one monolithic thing to me.
If there is no signal on output, I don't care if it is broken relay, or bug in code that simply don't switch on relay because of low quality of code.
If manufacturer provides quick and timely software fix, that is fine for small annoyances.
If they don't give good software and all the time something is wrong....
It does not work, i send crap back.
zrq:
True, and it seems the only way to get a controlled rise&fall time is to program an ARB. Hope burst of pulses is something that will be added to the half baked firmware.
BTW the fall time tested is even slightly faster of <1.7 ns . This is probably superior to SDG2000X though which specified to be <8ns iirc (only using one at work, no chance to test it).

If by superior you mean faster, than it is faster.. SDG2000X has cca 7-8 ns rise/fall times.
But if you don't need edges faster than 8 ns but good control than SDG2000S is vastly superiors to Rigol. Eye of the beholder and actual needs in practice rule...
