The E.05.00 release of the N7842A ENA application introduces two test plan variants: the Factory Recommended Variant and the Normal Variant. Having two variants is necessary in order to support varying solutions for testing dynamic accuracy.
The Factory Recommended Variant is the preferred variant. The E5080A ENA can only run the Factory Recommended Variant; the Normal Variant is not allowed. The E5071C and E5072A ENA models can run either variant.
A new solution was needed to test an enhanced dynamic accuracy specification on the E5080A. This new solution uses a 2-channel function generator which replaces the dynamic accuracy test set. The two dynamic accuracy tests from the previous E5080A test plan have been replaced with one new Dynamic Accuracy performance verification test that uses the function generator solution.
Because the dynamic accuracy test set solution in the Normal Variant test plan is insufficient for testing to the enhanced specification on the E5080A, only the Factory Recommended Variant is offered for the E5080A.
The E5071C and E5072A ENA models can use either variant. The Factory Recommended Variant is the preferred variant.
The new dynamic accuracy solution using the function generator is also available to the E5071C and E5072A in the Factory Recommended Variant. This new solution combines the previous two dynamic accuracy tests into one performance test. There are fewer connections required in the new function generator solution than in the test set solution in the Normal Variant.
The Normal Variant test plan for the E5072A is unchanged from the previous release. It supports the test set solution for dynamic accuracy.
For the E5071C using either variant, the Receiver Compression functional tests have been renamed and the new performance verification tests will use the hard dynamic accuracy specification.
New test name: Dynamic Accuracy at Compression – Low Freq
