Peak Cursors (Peak)
Using the threshold value (Threshold) and the difference between peak and valley (Excursion), the instrument
determines the frequency (Frequency) and level (Peak). Only the peaks that meet the threshold and excursion
conditions are displayed.
(a) Peak/bottom difference < measured value
(b) Peak/bottom difference > measured value
(c) Peak/bottom difference > measured value
(a)
(b)
(c)
This peak is displayed.
(The measured value is greater than the
threshold and the peak/bottom difference.)
This peak is not detected.
Threshold value
• Threshold (Threshold)
Set the threshold value for detecting peaks. Peaks that are greater than the specified values are measured.
This peak is detected. (This is greater than the threshold.)
This peak is not detected.
(This is less than the threshold.)
Threshold value
• Difference between peak and valley (excursion)
Peaks whose amount of change from the peak value (the difference between the peak and valley) is greater
than the specified value are measured.
20 dBV
10 dBV
5 dBV
Example: Excursion = 20 dBV
This peak is detected.
(The peak/bottom difference is
greater than or equal to 20 dBV.)
This peak is not detected.
(The peak/bottom difference
is less than 20 dBV.)
• List Display (List)
The list displays the following items. You can also jump to the maximum level (Jump To Max Peak).
No. Analysis number. Analysis results can be displayed in the range of 1 to 10.
Frequency Displays the peak frequency
Peak Displays the peak level
• Analysis Number (List No.)
The instrument moves to the selected number and displays the frequency and level.
