I have one and it's a fairly useful box; if nothing else it makes nice fast-rise time pulses. The only downside is the somewhat limited delay range -- the maximum you can delay the output pulse from the trigger is 180ms. It would be sooooo much cooler if you could delay by up to a full second. :-( One thing I use it for is synchronizing clocks. I run my main GPS receiver as close to dead on as possible, and have all the other clocks run some number of microseconds early in comparison. I set one GPS to run quite early (like 50ms) and use it to trigger the 5359A. Then, I adjust the delay on the 5359A and use that as the sync pulse for the clocks. Works real well, but again it would be so nice if it could handle a nearly 1 second delay.
