Q
Any tips for performance optimization?
A
The key thing to remember is to start with maximum sample rates and to make
sure that the mounting system is solid. Use all four screw holes if possible
and make sure they are tightened to at least 20-inch-ounces of torque, in order
to minimize the opportunity for introducing mechanical resonance. Starting
with the maximum sample rates and some FFT averaging (10-15 to start with) will
give the broadest view of the vibration spectrum on customer equipment.
Insights from this will likely identify optimization opportunities. The FFT
averaging function will reduce the noise floor (down to the noise density), for
those who find that they need the best resolution available. Remember; keep the
“starting point simple.” The ADIS16228 is a spectral analyzer for vibration,
except it doesn’t cost $10,000 and doesn’t require a back-support belt to lift
off of the table. It bolts their equipment and they start taking data. We
(ADI) are ready to help them understand and optimize their user-configurable
parameters, based on their initial observations and data. We believe that the
further customers get into this process, the more intuitive these principles
will become.
