Setting Up the List of Ripple Limits to Test

Two tasks are involved in preparing for ripple testing:
• First, set up the analyzer settings to view the frequency of interest.
• Second, set up the analyzer to test over the appropriate frequencies against your
specific limits.
This example will show you how to set up the analyzer to test ripple limits. In this
example, we will be testing the pass band of a bandpass filter where the center frequency
of the filter is approximately 1.8 GHz and has a bandwidth of approximately 2.9 GHz.
Refer to Figure 1-64.

Setting Up the Analyzer to Perform the Ripple Test
This section sets up the analyzer so that a bandpass filter can be easily viewed on the
analyzer display.
1. Connect your filter as shown in Figure 1-65.
