Here you go. Took me longer to find my USB stick than it did to work it out...
Case 1: 288ns at 1Hz, rise time 30ns.1. Set channel 1 to pulse mode
2. set 576ns as pulse width (this covers both high and low states so 288ns x2) pulse width and amplitude (I'm using 5v p-p)
3. set "leading" to 30ns.
4. Turn on burst mode and set burst to 1s, repeat to once.
Scope reports 287ns, 31ns rise time:
Case 2: 196ns at 1Hz, rise time 48ns.1. Set channel 1 to pulse mode.
2. Set 392ns as pulse width (this covers both high and low states so 196ns x2) pulse width and amplitude (I'm using 5v p-p)
3. set leading to 48ns.
4. turn on burst mode and set burst to 1s, repeat to once.
Scope reports: 197ns at 1Hz, rise time 49ns
Case 3: 200ms period, 50% duty cycle. Fastest rise time:1. Set channel 1 to pulse
2. Set 200ms period
3. 50% already set
4. Set leading and trailing to 10ns (lowest setting).
Scope reports, after some dicking around with triggers and memory depth 13ns rise time. Period and frequency are correct (not depicted):

Generator is capable of 25MHz which corresponds to a rise time of 14ns so it's spot on spec. More expensive ones have better rise times I suspect.

Edit: this is sooooo easy to use. I haven't even read the manual cover to cover yet, just the getting started guide and the spec sheet.
