High-Performance FFT Analyzer Featuring 90 dB Wide
The R9211E is a high-performance digital
spectrum analyzer weighing only 12 kg. It
incorporates the latest ADVANTEST technology
including a proprietary LSI, low-power-
consumption electronic circuit, and high-density
packaging.
This economical FFT analyzer is ideal for
acoustic, vibration, and noise signal analyses.
The measuring frequency range is from 10 mHz to
100 kHz and the 16-bit high
resolution realizes a
90 dB (typical
value) wide dynamic range.
The R9211E analyzes weaker signals than
conventional models can. The input sensitivity is
— 140 dBV (typical value in 2 kHz range) and the
variable function enables the frequency resolution
to be chaged from 25 lines to 3200 lines for
high-speed spectrum analysis or approximate
spectrum separation measurement.
In addition to these excellent characteristics, the
epoch-making FFT analyzer has a unique four-
domain (four measurement area modes) method
structured for a wide range of user applications.
You can select one of the four domain modes
according to the type of analysis that you want to
perform,
whether waveform measurement,
spectrum analysis, time-frequency analysis, or
frequency response function measurement. These
domain modes make measurement much quicker
and easier.
A wide variety of options such as a large memory
capacity, built-in floppy disk, and analysis by
16-bit
direct digital input meet your applications.
