Spectrum Analyzers
■ Measurement Domain Modes For Various Measu-
rement Domains
Since digital spectrum analyzers have many measurement
applications, there is a tendency for them to have many analysis
functions and for their operations to become complicated. In
order to free the user from such complicated operations, the
R9211 Series has separate measurement domain modes
according to the measurement application. The user can select
the desired measurement mode without having to trouble with
unused analysis functions or setting conditions. The sought-
after results can be obtained easily by making only the software
key settings necessary for the measurement.
• Waveform Measurement Mode
By using this mode, time domain signal analysis can be done
more quickly than was possible previously. Further, an anti-
aliasing filter can be turned on and off so that the series can be
used as a 16-bit/ 256 kHz sampling oscilloscope. This is ideal
for time domain transient phenomenon analysis of the sound
of acoustic instruments, starting characteristics tests of engines
or motors, waveform analysis of power on reset signals or
differential linearity tests of D/A converters.
• Time/Frequency Analysis Mode
In evaluation of musical instruments’ sound or hall reverberation
characteristics, time variation analysis can be done which
focuses on a specified spectrum. Further, analysis can be done
of the time characteristics of spectrum variations in the wow
and flutter component of VCRs or other equipment (frequency
monitor function). The time characteristics of phase variations
such as jitter can also be analyzed (phase monitor function).
• Spectrum Measurement Mode
Measurement is possible with a wide dynamic range of 90 dB
(typ.) and high sensitivity of -140 dBV (typ., at a 2 kHz range).
This is effective in harmonic distortion analysis and micro-
level noise analysis.

• Frequency Response Function Measurement Mode
In this mode, frequency resolution can be varied from 25 to 800
lines. Also, since 2 power supply channels for acceleration
sensors are built-in, direct measurements of transfer functions
of structural components are possible by connection of a sensor
with a built-in amp or an impulse hammer.
• Servo Analysis Mode (R9211B, R9211C)
The R9211 Series features a built-in summation amplifier for
open loop characteristics evaluation, servo measurement with
up to a 5 decade log sweep and a point servo measurement
function with a frequency table of only specified frequencies.
