In the above formula, the unit of trace data is dBm.
Note
Trace arithmetic functions are mutually exclusive, when an arithmetic function is applied to a trace, it will
turn off the last selected arithmetic function.
Operand A: Set operation trace 1 in the operation function. Trace 1, trace 2, trace 3, trace 4 are available for
selection.
Operand B: Set operation trace 2 in the operation function. Trace 1, trace 2, trace 3, trace 4 are available for
selection.
Offset: Set logarithmic offset in the operation function, unit is dB. User can change the offset by using the
numeric key, rotary knobs, direction key or touch panel menu.

Reading of Marker Cursor
It can display 10 markers on the screen at the time, but each time can only control one or a pair of
markers.
Select Marker: Select one of the ten cursors. The default is signed as marker 1. After selecting the cursor, it
can set parameters such as the cursor type, the marked trace, and the reading mode. The currently open
cursor will be marked on the trace selected by "Mark Trace", the current parameter area and upper right
corner of the screen will display the current active cursor reading at the marker.
Marker Mode:
1. Normal: For measuring X (frequency or time) and Y (amplitude) values in a point of trace. After selecting
normal, a cursor identified by the current cursor number will appear on the trace, such as “1”, pay
attention to the following points in using:
