In the above formula, the parameter unit is dB.
5.
Op1–Op2+Ref
Operand 1 (Op1) minus Operand 2 (Op2), and then plus the reference
(Reference). Then, saves the result to the destination trace. During the sweep,
the following formula is executed for each point:
Reference

In the formula, the unit for Op1, Op2, and Reference is dBm.
6.
Off
Disables the math function.
Note: The trace math functions are mutually exclusive. If you apply one math
operation to a certain trace, the last selected math operation function should be
disabled.
Op1
Selects Operand 1 to be used for the trace math functions. Operand 2 can be
configured with Trace1, Trace2, Trace3, Trace4, Trace5, or Trace6.
Op2
Selects Operand 2 to be used for the trace math functions. Operand 2 can be
configured with Trace1, Trace2, Trace3, Trace4, Trace5, or Trace6.
Note: The currently display trace does not involve in math operation.
Offset
Sets the log offset in the math operation function. The unit is dB.
Note: This menu is only valid when you select "Op1+Offset" or "Op1-Offset" to be
the math type.
