Hello. I'd like to prevail upon anyone who either owns or has access to any of these to answer a couple of questions on their capabilities and real-world performance.
a) Is it possible to single-shot the pulse waveform? From reading the User Guide, it doesn't appear so. Going by just the description of the front panel controls, the function of the manual trigger button seems limited to starting sweeps/bursts only. Surely it can do something as simple as a one-time pulse?
b) If a single-shot, manually triggered pulse is possible, is it also possible to configure a logic complementary output? i.e. have the output held positive (e.g. +3.5v), with a negative going pulse level (e.g. +0.5v) when triggered?
b) What are the fastest rise and fall times possible for a low frequency continuous pulse output? Lets say, 0.5Hz at 3.5v pk-pk 0v offset, 50% duty cycle, into 50 ohms.
On paper it seems a reasonably capable general purpose function generator but not, perhaps, the best choice as a pulse generator.
Thanks.
For those requirements Siglent SDG1000X/2000X/6000X can do all of the stuff you asked.
1. You get triggered single pulse by using N Cycle burst mode with number of 1 pulses. Rigol should do that too.
2. Yes. You can invert signal. Rigol should do that too.
3. Setting of rise time is not connected with repetition frequency or pulse width.
SDG2000X is on special right now... It is a 120 MHz, low distortion, 16bit design.
I'm not 100% sure, but I couldn't find a solution.
1. Rigol doesn't know, the Pulse waveform doesn't work in "Sweep and Burst" mode. The device also informs you about this: "Sorry unable to burst Pulse waveform"
You can do it with a square wave,
but it also includes the negative part.
If you set an offset, it is continuously active by activating the channel.When I tested it, I didn't check that the "Idle Level" was set to the center.

changed to 1st Pt, top or bottom is good.
Thanks to zrq for pointing it out.

2. can invert a signal and can set an offset3. Pulse in continuous mode 0.5Hz, 3.5Vpp 0 offset and 50%.
3ns for rise and fall.
the frequency doesn't affect it
but the pulse width is affected by the frequency.
At 1 Hz, 100us or 0.01%
100ns at 1kHz, which is also 0.01%
9ns at 1MHz, 0.09%
You cannot have a 1Hz pulse with a width of 9ns.
Unfortunately, there is no easy way to use your own wave yet, it is not possible to know for sure if burst or sweep would work with it.
