of the display. The conversion-loss versus frequency data is on the 
calibration label on the bottom of the Agilent 11974, or on the supplied 
calibration sheet.
Use the procedure “Entering Conversion-Loss Correction Data for 
Harmonic Mixers” on page 85. 
Step 7. To complete the amplitude calibration process, the preselector must be 
adjusted at each frequency of interest. Before making final amplitude 
measurements with the analyzer, perform the following: 
Press 
Peak Search.
Press 
SPAN X Scale, Span Zoom, 10, MHz.
Press 
AMPLITUDE Y Scale, Presel Center.
The final amplitude measurement can now be read out with a marker. 
See Figure 10-4.
