8:15 - 9:50
         Overview of Experimental Modal Analysis and Measurements Required
10:00 -10:30      Impact Basics — Hammer, Tips, Force, Accelerometers
10:30 -11:00      Shaker Basics — Shaker, Amplifier, Force, Impedance
11:00 -11:50      Perform a basic experimental modal test — overview the process: make measurements
1:00 - 2:00         Modal Primer — A Brief Overview of the Process
2:00 - 2:50         Hammer — Tips; Force/Exponential Window; Coherence — example measurements
3:00 - 3:50         Hammer — Double Impact; Over/Underload/Saturation — example measurements
4:00 - 5:00         Hammer - Multiple Impacts; Roving/Stationary Hammer — example measurements

February 27, 2019
 8:15 - 9:50
        Shaker — Excitation Signals for modal testing — example measurements
(random, burst random, pseudo-random, chirp, digital stepped sine)
10:00 -11:00      MIMO — FRF, Multiple Coherence — example measurements (or previous data)
(Shaker independence/PCA, shaker anomalies, number of shakers)
11:00 -12:00      Measurement Inconsistencies from Poor Testing — Implications for Modal Test
1:00 - 2:00        Impact Testing — Additional Items for Consideration
Frequency Range — Multi-bands; Skewed Inputs, ICP Low Frequency;
2:00 - 3:00         Shaker Testing — Additional Items for Consideration
Stinger types, stinger effects, impedance heads, general shaker set up
SLSO/MIIVIO, mass loading, effect on modal analysis (stability, modes extracted)
3:00 - 4:30         Closing Remarks - Q&A
