That may not work either,
Go with the 100KHz stop
Also needs to pick the right edge of the High freq stop signal.
If the edge that is picked is bouncing back and forth around the start pulse 
It don't work so good.

That won't work as one of the sources is the PPS output from an Oncore
GT which has a PPS error spec < 500ns with SA on.
Whilst it may be a little lower without SA, it may be still be somewhat
greater than 100ns.
Dividing the 10MHz down to 1MHz or perhaps 100kHz would be better.
The 5370A timebase noise contribution to the measurement error will
still be insignificant.

The plot doesnt appear too discordant with the Oncore GT spec.
