Other Settings

Other PNA settings can impact phase noise measurements such as IF gain, input attenuation, and so on. The ideal choices for these settings can depend on the carrier frequency and amplitude. See the PNA's operating manual for more details on how to adjust these settings to get the most accurate phase noise and jitter measurements.
