Choice of 4 Types To Fit the Application
R9211Series
■ 16-Bit Resolution, 90 dB (Typical Value) Wide Dynamic Range
90 dB (typical value) wide dynamic range spectrum measure-
ment has been made possible through ADVANTEST’s advanced
analog/digital signal processing technology. In order to take full
advantage of the functions of the built-in A/D converter, the input
sensitivity range can be varied in 1 dB steps. This is a powerful
feature for use in measurements of mechanical characteristics of
magnetic optical disks, distortion analysis or transient signal
analysis of audio signals and transfer function measurement
using an impulse hammer.
■ High Sensitivity Measurement of -140 dBV (Typical Value)
When used with a difference input, the R9211 Series attains highly
sensitive measurement of -140 dBV (at 0.1 µV, 2 kHz (typ.) range). This
is effective for analysis of noise in semiconductors or other devices.
■ ‘I/O + Memory’ Function Allows Direct 16-Bit Digital Input
The ‘I/O + Memory’ function is effective in evaluating A/D
converters or DSPs used in digital audio equipment such as DAT
and CD players. Spectrum or distortion analysis can be done by
inputting a digital signal directly after the A/D converter of the
R9211 Series in ‘16-bit + EOC’ (twos complement) data format.
■ A Wide Variety of Marker Analysis and Display Functions
The R9211 Series has a wide variety of marker analysis functions
which are effective for analyzing or making evaluations and
allowing for a reduction in measurement time. These include
a peak marker, next peak marker, harmonics marker, band
marker, overall power, attenuation power, partial power, average
power, dispersion and X dB marker. The series has been made
easier to use, offering simultaneous display of 1 to 4 screens,
overlapping display in the same domain or same analysis range
and 3-D display of up to 50 lines. There is also a bar display
function where the state of one of overall power, partial power,
average power or power dispersion can be checked at a glance.
R9211A/9211B/9211C/9211E
FFT Analyzer Series
R9211 Series are portable high performance digital spectrum
analyzers which gather the essence of ADVANTEST’s accumu-
lated 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 synthe-
sis.
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 (mea-
surement 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.
■ Wide Measuring Frequency Range of 10 mHz to 100 kHz
By using high precision analog and digital filters, aliasing
filters can be set in all frequency ranges from 10 mHz to 100
kHz. Frequency resolution can also be set from 25 to 3200 lines
in all frequency ranges according to the purpose of the analysis.
The scale function can be used to display the spectrum of only
the required frequency band on the CRT.
