This topic page applies to all supported ENA models in both the Factory Recommended and the Normal Variant test plans.
This test checks the frequency accuracy of the ENA test-port output signal. The frequency accuracy is checked at several frequencies with a frequency counter. Since the ENA employs a PLL frequency synthesizer for the signal source, a Frequency Accuracy Test at certain frequency points can verify the accuracy for the entire frequency range.
