Pulse Delay Unit used with AMI/S7l in UN14L/505 to delay
sync and blanking pulses as distributed. Basis delay time
is l~s; this can be increased to 2~s, 3~s 4~s or 5~s by
the fitting of one or more additional delay lines. 8
output connections are provided, one giving full delay and
each of the remainder any lesser delay to within t25ns.
