 Following these rules the first fundamental would be F1 and the second fundamental would be F2. You can use standard operations including "^" for exponents as well as parentheses to force the order of operations.
+Additional Examples:
+  * "F1 - 20" -> This is the first fundamental minus 20 MHz.
+  * "2F2 + 20" -> This is the second harmonic of the second fundamental plus 20 MHz.
+  * "-F2" -> This is the image of the second harmonic of the first fundamental
 === Single Side Band ===
 If the Units setting is "Bins", then this is the number of bins that will be used on each side of the center bin when calculating the power of the spur with spectral leakage compensation. If the Units setting is set to "MHz" then this value will be the number of MHz on each side of the center bin to use when calculating the power of the spur with spectral leakage compensation.
