Analysis and Processing of Result
Define the Peak
“Search the maximum/minimum peak” on page 228. It should be noted, however, that a
definition must be set in advance by using the
PEAK DEF D X
key and
PEAK DEF D Y
key
to ensure that the target peak is searched. To ensure that all peaks are detected, perform
peak search after setting the peak
D
Y value to zero using the
PEAK DEF D Y
.
Step 3. Press the
[Search]
key to display the Search menu.
Step 4. Press the
PEAK
key to display the Peak menu.
Step 5. Press the
PEAK DEF MENU
key to display the Peak Definition menu.
Step 6. Press the
MKR ® PEAK DELTA
key to enter the peak sharpness at the main marker
position into the peak definition of
D
X and
D
Y .
NOTE
When using the
MKR
®
PEK DELTA
key to define the peak, the sharpness of the left side
(where the sweep parameter value is smaller) of the peak at the main marker position is
used to define
D
X and
D
Y.
With both the
D
marker and the main marker displayed on the screen, if you press the
MKR
®
PEK DELTA
, the sweep parameter value (absolute value) of the difference between the
main marker and the
D
marker is assigned to the definition of
D
X; correspondingly, the
measurement parameter value (absolute value) of this difference is assigned to the
definition of
D
Y.
