5. Configure generator #1:

a. Set carrier frequency = 106.1 MHz.

b. Set RF level = 70 dBµV.

c. Select FM Modulation.

i. Set FM Deviation = 22.5 kHz.

ii. Set Source = LFGEN.

iii. Set LFGEN frequency = 1 kHz.

d. Enable modulation.

e. Enable carrier.

6. Configure generator #2:

a. Set carrier frequency = 102.1 MHz.

b. Set RF level = 70 dBµV.

c. Disable modulation.

d. Enable carrier.

7. Simultaneously adjust the generator #1 and generator #2 RF level, VRF1, until SINAD = 26 dB.

8. IP3 (dBµV) = VRF1 + ½ (VRF1 – VRF0).
