WebAdditionally, the so-called third order intercept point (IP3) can be calculated. It is a theoretical point, where the intermodulation products at the DUT’s output grow as large as the original tones at the DUT output side. The IP3 can be derived on a logarithmic scale (i.e. all values in dBm or dB) as IP3 P Tone P ' /2. (6) Web22 jan. 2024 · There was an improvement of 0.5dBm in the measurement of the mixer’s IP3. This is only slightly more in-line with the VNA measurement. This 0.5dBm change could practically be only attributed to measurement uncertainty. The measurement uncertainty in our Rohde and Schwarz FSW85 is 0.3dB for this measurement frequency. WebIP3 or IMD3 refers to third order intermodulation distortion products power.
