2.10.2. Setting the Frequency of the Reference Signal

The Frequency Selection panel allows you to compute the reference signal frequency that ADC performance tests require. This frequency is critical and affects the validity of your test results. The computed frequency varies depending on the type of test you want to do with the ADC Toolkit.
Figure 13. Frequency Selection Panel

To set the frequency of the reference signal:

  1. On ADC Channel, select the ADC channel that you plan to test.
    The tool populates the Sample Size and Sample Frequency fields.
  2. In Desired Frequency, enter the target frequency for testing.
  3. Click Calculate.
    • The closest frequency for valid testing near your desired frequency appears under both Signal Quality Test and Linearity Test.
    • The nearest required sine wave frequencies are different for the signal quality test and linearity test.
  4. Set your signal generator to the precise frequency given by the tool based on the type of test you want to run.
