Creating and Applying User Flatness Correction
Save the User Flatness Correction Data to the Memory Catalog
This process allows you to save the user flatness correction data as a file in the signal generator’s memory
catalog. With several user flatness correction files saved to the memory catalog, specific files can be
recalled, loaded into the correction array, and applied to the RF output to satisfy various RF output flatness
requirements.
1. Press
Load/Store
.
2. Press
Store to File
.
3. Enter the file name FLATCAL2 using the alphanumeric softkeys and the numeric keypad.
4. Press
Enter
.
The user flatness correction array file FLATCAL2 is now stored in the memory catalog as a UFLT file.
Applying the User Flatness Correction Array
1. Press

Return
>
Flatness Off On
.
This applies the user flatness correction array to the RF output. The UF indicator is activated in the
AMPLITUDE section of the signal generator’s display and the frequency correction data contained in the
correction array is applied to the RF output amplitude of the mm-wave source module.
Recalling and Applying a User Flatness Correction Array
Before performing the steps in this section, complete the section “Creating a User Flatness Correction Array
with a mm-Wave Source Module” on page 69 .
