Agilent 70820A User-Corrections

User corrections provide a convenient method for modifying the display of

input signals. Some of the applications for user-corrections include the follow-

ing:

• Filtering input signals to simulate the effects of circuit design.

• Compensating for frequency and phase response of external probes.

• Compensating for frequency and phase response of external test setups.

• Compensating for the frequency response of optical to electrical converters.

To create and use your own user-corrections, enter the User Correction menu.

(This menu is located under the 70820A’s Calib menu.) The microwave transi-

tion analyzer maintains two separate user-correction memories: one for chan-

nel 1 and one for channel 2. After entering the User Correction menu, the

microwave transition analyzer displays user-correction data in the lower half

of the screen. The screen’s upper half remains dedicated to showing the nor-

mal display. Or, if the displayed trace is assigned to the data, the trace shows a

graphical representation of the filter, as the following figure shows. To learn

how to assign a trace to user-corrections, refer to “Viewing User-Correction

Data” on page 3-56.
