  • CF-9200/9400

The CF-9200 and CF-9400 are an all-in-one portable FFT analyzer. All FFT analysis operations can be performed with the integrated hard keys and capacitance type touch panel without requiring an external PC for analysis. The new, exclusively developed 100kHz high-performance analysis front-end system incorporating a 24-bit A/D converter enables easier and more reliable analysis of noise and vibration generated by plant lines, pumps, motors, automobiles, railway vehicles, home electrical appliances and devices, and electrical and electronic parts than previous models. The CF-9200 and CF-9400 also offer solutions for field workers in their FFT analysis, including the resonance and frequency characteristics of mechanical structures in a vibrating environment with electromagnetic vibrators and impulse hammers.


Speedy: Keys and a touch panel for quick, light and intuitive operation

With the CF-9000 series, basic FFT analysis operations such as display, measurement, stopping, recording and readout can be made positively and quickly through the large hard keys. The touch panel provides an intuitive interface, allowing the operator to easily perform a range of operations with a swipe or tap, such as selecting the number of waveforms displayed and extending or shortening the X and Y axes to the desired scale.

Flexible: Hot-swap & cordless 5 hours operation

With the CF-9000 series, the two on-board, large-capacity lithium ion secondary batteries enable continuous cordless operation of up to 5 hours*1. The hot-swap function allows the batteries to be replaced while the unit is powered on, enabling the analysis or recording operation to continue while eliminating the need for resetting. The unit can also be recharged while in operation*2, helping to reduce the number of peripherals that would otherwise be needed.


*1When CF-9400 4ch CCLD ON.
*2Full recharge takes 8 to 9 hours with the power on and 4.5 to 5 hours with the power off.

Versatile: Recording & performing analysis (FFT or RTA) simultaneously

The unit is compact but versatile, capable of carrying out a range of operations from FFT analysis, real-time octave analysis (RTA)*1 and rotation tracking analysis*2, to linear/log sweep analysis using signal output and electromagnetic vibrator control*3. The unit can also perform simultaneous analysis and recording operations, allowing offline analysis back in the office using the CF-9000 main unit and software applications.


*1 Octave analysis software (CF-0923) is required.
*2 Tracking analysis software (CF-0922) is required.
*3 Log sweep/excitation control software (CF-0942) is required.

Quiet: Noise or vibration-free operation in a fan-less, spindle-less design

The CF-9000 series offer high performance without fans or spindles. The unit does not produce mechanical operating noise or vibration, and so cannot be a source of noise or vibration in acoustic or vibration measurement/recording locations.
The unit can be operated remotely on a tablet etc. via wireless LAN adapter*. *Using Microsoft® "Remote Desktop."


Standard function

Real-time tripartite graph display function(* Vibration Criterion Curves)

The CF-9200/9400 comes with a new real-time tripartite graph display function. (Note)
During FFT analysis, three amplitude values (acceleration (m/s2)/velocity (m/s)/displacement (m)) for an arbitrary frequency can be read out in real time. This function will eliminate the need to convert the amplitude by carrying out differentiation and integration individually by the frequency analysis function as with the previous models, thus enabling data at that amplitude to be read speedily.
Displaying VC curves after 1/3 octave processing helps to judge the allowable vibration reference or setting environment evaluation of precision instrument which is sensitive for vibration such as AFM, electronic microscope and laser interferometer.

*1 Amplitude of acceleration (m/s2) and displacement (m) based on the velocity (m/s) on the frequency axis (Hz) can be read by Tripatite graph (image).

*2 VC Curves are proposed as the allowable minute vibration reference of when precision instrument is set. The evaluation by 1/3 octave band width is used in VC Curves. The standard is divided into five stages in increments of 6dB (VC-A, VC-B, VC-C, VC-D, and VC-E) depending on the purpose of use such as optical microscope and laser instrument with long optical path.

Wide & dynamic range

The CF-9000 series features a new 24-bit A/D front-end system, offering 120dB wide dynamic range. This eliminates the need for voltage range change in A/D oversampling, which otherwise needs to be frequently performed in acoustic or vibration measurement. Measuring and data recording do not need to be repeated, making calculation and analysis much more efficient and the FFT analyzer easier to operate even for novices.

Isolated all inputs

With the CF-9000 series, all signal input channels are isolated (insulated). Highly resistant to ground loops and noise, the unit offers highly reliable measuring performance in locations prone to potential difference.
The isolation scheme also protects the crucial areas of the FFT system from sensors or signals that can be exposed to harmful transient voltages.

CCLD equipped, TEDS available

By each input channel with CCLD, an accelerometer with built-in preamplifier, charge convertor for charge output type accelerometer or a microphone can be connected directly to the CF-9200/9400. And using TEDS sensor enables power supply and unit calibration to sensor automatically.


*CCLD(Constant Current Line Drive)means the sensor interface using Constant Current Supply. CCLD from an accelerometer with built-in preamplifier or a microphone preamplifier enables direct connection to an FFT Analyzer without using external amplifier. 2 to 4 mA of CCLD is commonly used.


*TEDS(Transducer Electronic Data Sheet)is a general term for the method which contains information relevant to the sensor. It is defined in the IEEE 1451 series. As information of the sensor is automatically read to the TEDS available measurement devices or amplifiers, the user is ready to take measurements. It can avoid setting error and also saves you time and effort of troubling calibration and measurement preparation.

Easy operation through a touch panel interface

The CF-9000 series employs a 10.4 LCD capacitance type touch panel, allowing the operator to pinch and swipe FFT graphs. The band or gain of your choice can be widened or narrowed with a simple and intuitive action.

Reliable inputs with the new hard keys

With the CF-9000 series, operations such as turning the power on and off, changing data types and saving data are carried out using the new large hard keys. The positive feel of these keys assists fast and correct input even in unstable or dark sites, helping to prevent failures to save data and malfunctions caused by inadvertent inputs.
Lock function(HOLD)for hard keys and touch panel are also effective.

Highly visible LED indicators

The status of major FFT operations are shown by LED indicators. The hard keys for major functions also have LED indicators. This enables the operator to monitor FFT operations even from a distance, such as the power-up process, the charge status of the secondary batteries and A/D oversampling.

Cable disconnection detecting function

Automatically detects cable disconnection or connector trouble of an accelerometer and a microphone*, preventing trouble before measurement. With the CF-9000 series, this function can be made disable.


*Built-in preamplifier CCLD type

FFT Basic Analysis Function

Time-axis waveform


Performs A/D conversion of the raw waveform of an electrical signal of vibration, noise, pressure, strain, etc. coming from a sensor and then displays the result as time-domain data. The X and Y-axis values at any point can directly be read using the search cursor. The delta cursor function makes it easier to read the time difference and level difference. The time-axis data analysis function enables quantitative time-axis waveform analysis and diagnosis of such items as mean value (MEAN), root mean squared value (RMS) and crest factor (Crest Factor).

Power spectrum

The power spectrum in FFT analysis shows the magnitudes of frequency components of a sampled time-axis waveform, in the form of a graph indicating the power for each frequency band (frequency resolution Δf) on the horizontal axis.

The power spectrum analysis enables detection of abnormal conditions of a facility, which are difficult to estimate through measurement of vibration and noise level and observation of raw time axis waveform. The natural frequency of a structure can also be measured.


In a mechanical system or an electrical circuit, the input-to-output ratio is shown in gain and phase characteristics with the X axis representing frequency.

The gain characteristics indicate how the amplitude of input signals changes as they pass through the transfer system being evaluated. The ratio of the output amplitude to the input amplitude is plotted on the Y axis in decibels.

The phase characteristics indicate phase advance/delay between the input and output signals with the Y axis plotted in degrees or radians.

Optional Analysis Software

Tracking Analysis Software (CF-0922)


For rotating machines such as engines and motors that have a wide range of operating speed, resonance caused by the natural frequencies of the machine parts and specific operating speeds can be a serious problem.

The tracking analysis software (CF-0922) clearly presents in visual form which speeds of the rotating machine have increased noise and vibration and which parts of the machine are contributing to the problem.

Octave Analysis Software (CF-0923)


The highest note of an octave has twice the frequency of the octave’s lowest note. As the frequencies of sound increase in geometric progression, the octave analysis software (CF-0923) is an effective tool for noise analysis.

By using 1/1 and 1/3 octave bandpass filters, it is capable of obtaining the sound pressure level of each band of the audible frequency range of the noise being measured.

Log sweep / excitation control function (CF-0942)


The Log sweep function is used to evaluate the resonance points of a transfer system by continuously changing the frequency of the driving sine waves from a 1ch signal output module (CF-0971). By sine-sweeping the X axis with a LOG scale, it is possible to obtain the gain and phase for each single frequency and an accurate response function with a high S/N ratio. The vibration control function limits the amplitude of an electromagnetic vibrator to a desired range, enabling vibration testing without having to consider the frequency characteristics of the vibrator.
