Impulse hammer
With the impulse hammer, the mechanical impedance or resonance
characteristic of a structure can easily be measured. The hammer is
very easy to use. Simply attach an accelerometer to the item and hit
the item with special hammer. The transfer function and mechanical
impedance can be measured on a realtime basis by inputting the
signals from the hammer and accelerometer to the R9211 model.
Several different hammers are available; choose the best one for
your purpose. Contact your nearest sales office or the sales
promotion department of ADVANTEST.

• Accelerometer
During the development of a structure or an equipment unit, vibration
and shock measurements are very important means of testing or
monitoring their operations. Using the accelerometer to sense
vibrations gives high sensitivity and excellent frequency and
amplitude characteristics. The accelerometer is compact, lightweight
and has a long service life. It is easy to use for many purposes. There
is also a wide selection of vibration detection elements, just a few are
shown here. For further information about them and their connection
to ADVANTEST's digital spectrum analyzer, contact your nearest
sales office or the sales promotion department of ADVANTEST.
