3. GOALS
Identify the modal vibration resonant frequencies of a microwave cavity
filter and its tuning elements.
Provide the results to the electronic engineering staff.
Understand self generated electrical signal noise due to mechanical
shock sources such as:
pyrotechnic explosive events – shipboard rapid gun fire
HALT testing with hammer blows
4. WARNING HALT/HASS
Microwave engineers – please note HALT “vibration” machines use
hammer blows to generate 3 axis excitation.
The exciting signal felt by the tested units will have significant shock
components above 2KHz.
Very small components can be damaged during HALT and HASS.
