Advantest R9211C

R9211 Series are portable high performance digital spectrum
analyzers which gather the essence of ADVANTEST’s accumulated
technologies such as usage of dedicated LSI circuits and
high density mounting technology as well as development of
circuits with low power consumption.
The R9211 Series consists of 4 types so that the best choice can
be made to suit the application. These types are the economical
R9211E; the R9211A capable of running zoom; the R9211B ideal
for servo analysis; and the R9211C which can do servo analysis
as well as curve fitting and frequency response function synthesis.
All these types have the wide measurement frequency range of
10 mHz to 100 kHz, a high 16-bit resolution and a wide dynamic
range of 90 dB (typical value). The series also has high sensitivity
input of -140 dBV (typical value, 2 kHz range) and a function
which allows variation of the frequency resolution from 25 to
3200 lines. These features are effective in isolated measurement
of micro-level signals and adjacent spectrum. Of course, the
series offers more than just these excellent functions. By means
of ADVANTEST’s exclusive systematized domain method (measurement
domain mode), measuring time has been shortened
over conventional FFT analyzers and operation simplified for a
wide range of user applications.
Other features include an increased memory capacity, built-in
floppy disk drive and 16-bit direct digital input analysis which
are available as standard (optional for some models). These
features meet a wide range of applications.
