b. Enter the appropriate average conversion-loss value. On Agilent 11970 Series harmonic mixers,
these values are listed on the mixer, or a calibration sheet that is supplied with the mixer. The
11970A, Q, and V band mixers calibrated after May 2011 have two calibration sheets. Use the
sheet that contains the text "Not for use with the Agilent X-Series signal analyzers". The U-band
mixer used for this example had an average conversion loss of 23.5 dB, as shown in
