Q
Executing a Notch Search
1. Place the active marker on the desired point on the trace on which
the notch search is executed. The response value of this active
marker itself is the insertion loss in the notch search (loss).
2. Press
Marker Search.
3. Press Notch Value and enter the notch value in the entry area that
appears.
4. Press Notch to turn on the notch search. In the upper left of the trace
display, six bandwidth parameters are displayed (see the figure
below).
300
Lower frequency of the 2 points on both sides that
have the measurement value apart from the active
marker position by the notch value.
Higher frequency of the 2 points on both sides that
have the measurement value apart from the active
marker position by the notch value.
Frequency of the middle point between the lower
cutoff point and the higher cutoff point (high +
low)/2.
Frequency difference between the higher cutoff
point and the lower cutoff point ( high – low ).
Value obtained by dividing the center frequency by
the bandwidth (cent/BW).
