2.1.2.1 Coefficients/Results Results are also called Coefficients in L3 Series software. Coefficients can be requested measurements prior to the test or as measurements after the test is completed, including derived and calculated results. NOTE L3 Series software gives you complete flexibility to get a result at any time from the acquired data for your test run. You can request a result before or after completing a test run. Here is a list of different coefficients that you can obtain using L3 Series software. Many of these are shown in the examples in User Guide 5 - Analyzing Your Test Results .
