The following examples demonstrate the user
flatness correction feature:
1. Using an Agilent 437B power meter to
automatically enter correction data for a swept
2 to 18 GHz measurement.
2. Manually entering correction data for a
stepped (list mode) measurement.
3. Automatically entering correction data for an
arbitrary list of correction frequencies when
making swept mm-wave measurements.
4. Making scalar analysis measurements with
automatically-entered correction data that
compensates for power variations at the
output of a directional bridge.
5. Setting up user flatness corrections in computer
controlled measurement systems.
Each example illustrates how to set up user
flatness correction for a different measurement
requirement. You may modify the instrument
setups shown to suit your particular needs.
Completed correction tables may be easily edited if
more correction data is required for your measure-
ment. Additional correction frequencies may be
added by using the auto fill feature or by entering
correction frequencies individually. The auto fill
feature will add but not delete correction frequencies.
Refer to the 8360 User’s Guide for a more detailed
description of the operating modes, hardkeys,
softkeys, and other features.
To simplify the execution of these examples, the
keys to be selected have been bracketed to differ-
entiate them from other text. The 8360 front panel
hardkeys are capitalized, while the softkeys they
access are in italics.
For example: POWER [MENU] - POWER refers to
the source’s functional grouping, [MENU] refers to
the hardkey the user must select in that function.
Auto Fill [Start] - [Start] refers to the softkey the
user selects to enter the first correction frequency
for the auto fill feature.
