• Trigger sensitivity is defined as the minimum peak-to-peak sine-wave signal
amplitude required to show the test signal with horizontal jitter
of
less than 3%
of
one period (p-p viewed over two seconds),with trigger
LEVEL
control set
at
midrange level, but not at control extremes.
b External trigger signal from a
50
n source driving a 50 n coaxial cable termi-
nated in 50 n at the input connector.
