The delay from detecion of an input trigger to the TTK output going high is approximately 2 µs:
(Lower trace is trigger input, upper trace is TTL output from 932.)
The TTL output is asserted for 20ms to make it reliably detectable by a wide range of hardware:
Note that the 10 µs input pulse is barely visible in the lower trace here because of the longer sweep duration.)
