scope:
Shaker system control software generates a self check immediately prior to a test at a signal level that is normally considered to be of insignificant strength compared to test levels. During a dynamic test of the Juno High Gain Antenna, however, the self check excited a response that exceeded the level from the subsequent test. In planning for dynamic testing, ensure that the self check signal will be set lower than any test level.
