value by using the numeric key, rotary knob, direction key or touch panel menu.
Marker->: [Marker] key in the panel menu "Marker->".
PK Search: Use the normal cursor mode to search for the highest amplitude in the trace and display the
frequency and amplitude value, then press peak search to perform it one time.
Next PK: Find the peak on the trace that is second only to the amplitude to the current peak and meets
the search criteria, and mark it with the cursor. Without this peak, the marker will not move.
Next PK Left: Find the current peak on the left side and search the close peak that meet the search
criteria on the trace, and mark it with the cursor.
Next PK Right: Find the current peak on the right side and search the close peak that meet the search
criteria on the trace, and mark it with the cursor.
Min Pk: Find the minimum amplitude value on the trace and mark by the cursor.
Pk-Pk Search: Perform peak search and minimum search at the same time, the result of peak search
marked with the reference cursor, the result of minimum search marked with the difference cursor.
Continue Peak Search（On/Off）: Turn on/off continuous peak search, the default setting is off. When
continuous peak search is turned on, the spectrum analyzer automatically performs a peak search after
each sweep, which is used to track the measuring signal.
Peak Table（On/Off）: Turn on/off peak Table, the default setting is off.
Turn on peak Table, a list of peaks that meet the search parameters (display frequency and amplitude) is
