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 DX key and PEAK DEF DY key
to ensure that the target peak is searched. To ensure that all peaks are detected, perform
peak search after setting the peak
DY value to zero using the PEAK DEF DY.
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
DX and DY .
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 DX and DY.
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 DX; correspondingly, the
measurement parameter value (absolute value) of this difference is assigned to the
definition of DY.
