15. Determine which signal is larger (signal at 3.499851 GHz or signal at 3.500151 GHz). Use the larger
value for "max" to calculate the TOI for 3.5 GHz (refer to the following example calculation):
TOI = –20 + [(–20 – max)/2] dBm
Example: Assume max = –90 dBm, then: TOI = –20 + [(–20 – (–90))/2] = +15 dBm
16. Record the 3.5 GHz TOI calculated measurement in Table A-7, “Spectrum Analyzer Calculated Third
Order Intercept” on page A-3.
