I would not use such a narrow pulse for any of those reasons except
for power if that was an issue. I would and have however used narrow
pulses simply because it allows for a lower volt*time product on a
transformer.

Hi
It is sort of an " everybody does it " sort of thing. Various justifications:
Less power is used / less heat in the drivers and terminations.
Transformer coupling works better ( lower delay ) with narrow pulses
Anything over 1 us has been "really long" in terms of lo
I asked this very question a few years back... the consensus was to lower power
dissipation into the typical 50 ohm load.

Can I ask why PPS pulses are so narrow? It makes them difficult to see on
a 'scope, and difficult to detect on a PC. And, as Bob said, far less
obvious if you trigger off the wrong edge.
