Something like this should work. See also the unittests and the tdr example.
latency = seconds_to_mu(1*us) # or whatever ends up working reliably
t = now_mu()
delay(10*us)
self.ttl2.pulse(10*us) # connect ttl2 to pmt0
at_mu(t)
self.pmt0.gate_rising(100*us)
r = self.pmt0.timestamp_mu()
if r > 0: # pulse received during gate
at_mu(r + latency)
self.ttl1.on()
