Making Measurements

Making a Power Measurement using Broadband Detection

Perform a Normalization Calibration

Normalization is the simplest type of calibration. The analyzer stores a
measurement trace into memory and divides subsequent measurements
by the stored data to remove unwanted frequency response errors. This
calibration is used for the power measurement to remove the
insertion-loss error of the test cable. Changing the frequency span or
number of measurement points will invalidate a normalization
calibration.

Execute the following steps to perform a normalization calibration:

1. Connect the equipment as shown in

Figure 3-18

.

2. Set the following frequency parameters:

3. Press

This stores the data into memory and divides subsequent
measurements by the stored data to remove frequency response
errors.
