The AC coupled output of the PV16 may be converted
to a LVTTL pulse output with fixed width by coupling the output of the
PV16 to the P2TTL box. The width of the TTL pulse is either fixed at
the factory, or may be adjusted by an internal slider to up to 20 ns. Converting
the sub-nanosecond PV16 output to a LVTTL pulse may be necessary for
compatibility with older devices which were not designed to count faster
than 10 to 100 Megahertz. In some cases it is necessary to make the
output pulse width compatible with a digital sample rate.
trace in the oscilloscope picture is the output of a PV16 pulse, and the
bottom trace is the absolute minimum pulse width from the P2TTL box.
