High-Speed Electronics and Data Processing
The RSA-G2 is equipped with new high-speed electronics with digital signal processing
for transducer measurements and motor control. While many manufacturers cut costs
by combining the test station and electronics into a single box, the separate electronics
approach of TA Instruments RSA-G2 isolates the precision measurements from heat
and vibration. This approach ensures the best sensitivity and data quality from the
test station. The electronics enable fully integrated high-speed data acquisition for
transient (up to 87 000 Hz) and oscillation (up to 15 000 Hz) measurements. The high
sampling speed provides superior resolution of magnitude and phase of the measured
signals, and allows much better higher harmonic resolution for automatic analysis during
oscillation tests or post Fourier transformation analysis. Higher odd harmonics that occur
in the stress (force) signal in oscillation tests are a result of non-linear response. The ratio
of the fundamental frequency to odd harmonics, such as 3rd, 5th, etc. can be calculated
and stored as a signal. In addition, the real-time waveforms during oscillation tests can
be displayed and saved with data points. The intensity ratio and quality and shape of the
waveform are invaluable data integrity and validation tools.
This graphical interface adds a new dimension in ease-of-use. Interactive activities such
as clamp zeroing, sample loading, and setting temperature can be performed at the
test station. Important instrument status and test information such as temperature, gap,
force and motor position are displayed. The touch-screen also provides easy access to
instrument settings and diagnostic reporting. The keypad at the base of the instrument
allows for easy positioning of the measurement head.
