2. To measure the side lobe ratio, with the marker still at the center
frequency of the main lobe, press
NEXT PEAK
of the main lobe and the side lobe is the side lobe ratio.

3. The pulse width is also easy to identify. The pulse width is the
reciprocal of the frequency difference between two envelope peaks.
To determine this difference, continuing from the last procedure,
press
MARKER 1/DELTA
4. The pulse width is equal to the time value displayed in the active
function block on the spectrum analyzer screen, as in Figure 2-87.
For best pulse-width accuracy, measure the distance between two
adjacent lobe nulls by manually adjusting the marker positions. If
desired, first reduce the resolution bandwidth for sharper nulls.
