TIME JITTER
The delay time, however, can in this case no longer
be read in the above mentioned way.
Possible time jitter of pulse P with respect to the
clock-pulse causes a haze and can be measured in
the position "A DEL'D BY B" by means of the cal-
ibrated time co-efficients of time-base A. (Fig. 8).
If the measurements are impeded by time jitter, the
latter can be eliminated by setting switch "DEL'D
TRIGG." to position "SETS A READY" and by
adjusting the controls of time-base A so, that time-
base A is triggered.
