Operation
Using the Mixers with the E4407B Spectrum Analyzer (Option AYZ)
Amplitude Calibration
The conversion loss versus frequency data can be entered on your analyzer from one of three sources.
•From a Conversion Loss Data Disk, supplied with your mixer.
• Data from the calibration sheet supplied with your 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’. An example of the calibration sheet is shown in
Figure 2-20 on page 58.
• From conversion-loss data located on the mixer body label.
Using a Conversion-Loss Data Disk
The conversion-loss data for your mixer can be quickly loaded in the memory of an ESA or PSA series
analyzer from a floppy disk. The following process works with the floppy disk provided by the factory
with your new mixer, or with one that you have stored the correction data. This process eliminates the
time consuming and sometimes error-prone process of manually entering the data from a table.
Loading Data
1. Insert the conversion-loss data disk (from the factory or your own) into the floppy drive of the analyzer.
2. Press
File, then Load.
3. Press
Type, More, then select Corrections.
4. Press
Directory Select, highlight drive -A-, then press Directory Select again.
5. Use the down arrow to select the file. The factory supplied disk has a file with the OTH extension which places
the data in the corrections set “other” location.
6. Press
Load Now to load the conversion loss values into the correction table of the analyzer.
Viewing Data
1. Press
Amplitude, More, Corrections, Other (ON) and Edit to view the correction values.
2. Use the front-panel knob or up/down arrows to scroll through the list of correction values.
