High-Performance FFT Analyzer Featuring 90 dB Wide The R9211E is a highperformance d i g i t a l spectrum analyzer w e i g h i n g o n l y 12 kg. I t incorporates the latest A D V A N T E S T technology i n c l u d i n g a proprietary LSI, l o w p o w e r c o n s u m p t i o n electronic c i r c u i t , and h i g h d e n s i t y packaging. T h i s economical FFT analyzer is ideal for acoustic, v i b r a t i o n , and noise signal analyses.
Dynamic Range And-140 dBV High-Sensitivity input Wide Measuring Frequency Range from 10 mHz to 100 kHz The combination of highprecision analog and digital niters enable an aliasing filter to be set for any frequency range from 10 mHz to 100 kHz. The frequency resolution can be set from 25 lines to 3200 lines i n each frequency range from 10 mHz to 100 kHz, according to the purpose of analysis, The scale function enables you to display only the spectrum of the band that you are interested i n .
Four-domain System for Easy Operation Easy-to-use Four-domain FFT Analyzer Digital spectrum analyzers usually have many functions for a wide range of measurement purpose. They are hard to operate because everything must be included, even i f only a few functions are needed at that time. The R9211E makes it m u c h simpler. It has o Waveform Measurement Mode • Spectrum Measurement Mode In this mode, the analyzer can analyze a signal in the time domain faster than conventioanl models can.
Abundant Handy Analysis And Display Functions Standard Memory 64K-byte/2-channel Memory Extension The R9211E has two channels of 64Kbyte memory. If necessary, an I/O + memory or CMOS memory can optionally be added up to 1 M words. The CMOS memory is particularly useful for analysis i n vehicle or other test environments where Possible a floppy disk memory cannot be used. The R9211E can also store measurement data and panel settings i n the internal l M b y t e 3.

FFT A ccessories Impulse hammer With the impulse hammer, the mechanical impedance or resonance characteristic of a structure can easily be measured. The hammer is very easy to use. Simply attach an accelerometer to the item and hit the item with special hammer. The transfer function and mechanical impedance can be measured on a realtime basis by inputting the signals from the hammer and accelerometer to the R9211 model. Several different hammers are available; choose the best one for your purpose.
Introduction ofR9211 Optimum model for servo analysis R9211B FFT Servo Analyzer This model contains a floppy disk and a signal generator, so it is ideal for vibration analysis of a structure or for measurement of a servo circuit. Available for curve-fit analysis R9211C FFT Servo Analyzer This is the top model of the series featuring curve-fit, frequency response synthesis, digital I/O, and highspeed servo analysis functions.
