The highlighted text informs the engineer that the conversion loss data emulates the Keysight PSA external mixing conditions. The predetermined settings for the PSA consists of LO power of 15.5 dBm, IF of 321.4 MHz, and multiplier (n) of 16. The harmonic mixer also accepts bias to further optimize the swept frequency response, which is 3.27 mA. Using these conditions as guidance, an engineer can setup synthesizers, a power meter, a power supply and some accessories to conduct conversion loss measurements
