Portable 2-channel/4-channel FFT Analyzer
CF-9200A/CF-9400A
The function of innovation is wrapped in a tough body.
The CF-9200A/CF-9400A (CF-9000A series) is an all-in-one portable-style FFT analyzer. It allows full operation of the FFT analyzer using only the hard keys and capacitive touch panel on the main unit, without the need for a separate PC for analysis.
Equipped with a newly developed 24-bit A/D converter and a high-performance front end with 100 kHz analysis capability, it enables easier and more reliable analysis of noise and vibrations emitted by mechanical devices such as plant piping, pumps, motors, automobiles, railways, and home appliances compared to conventional models. It also responds to field solutions requiring FFT analysis, such as resonance and frequency characteristic analysis of mechanical structures using electromagnetic exciters and impulse hammers.
The CF-9200A/CF-9400A performs basic operations of the FFT analyzer such as display, measurement, stop, recording, and reading with large hard keys. It guarantees reliable and speedy operation.
Settings for the number of waveform displays and zooming in and out of the X and Y axes can be intuitively operated using swipe and pinch gestures on the touch panel. It can be easily changed to the desired scale.
The CF-9200A/CF-9400A is equipped with two large-capacity lithium-ion rechargeable batteries, enabling cordless operation for up to 8 hours of continuous use.
Additionally, it features a hot-swap mechanism that allows for battery replacement while the power is ON, enabling measurement tasks to continue without interruption or reconfiguration during analysis or recording work. The built-in battery can also be charged while in operation ※.
※ Approximately 7-8 hours to full charge with power ON.
Approximately 7-8 hours with power OFF (at an ambient temperature of 20 °C).
FFT analysis, real-time octave analysis (RTA) ※1, rotation tracking analysis ※2, as well as linear/Log sweep analysis using signal output and amplitude vibration control of electromagnetic vibration systems ※3 are all condensed into a portable unit.
Simultaneous recording during analysis is also possible, and offline analysis can be performed with the CF-9200A/CF-9400A main unit and surrounding software.
※1 An octave analysis function (CF-0923) is required.
※2 A tracking analysis function (CF-0922) is required.
※3 A Log sweep/vibration control function (CF-0942) is required.
The CF-9200A/CF-9400A achieves high-performance operation without fans or spindles. It does not emit mechanical noise or vibrations from the main unit. In the field of acoustic and vibration measurement and recording, the CF-9200A/CF-9400A main unit does not become a source of noise or vibration.
By attaching a wireless LAN adapter, it is possible to operate the main unit using a tablet device, etc., without touching the CF-9200A/CF-9400A main unit ※.
The CF-9200A/CF-9400A can simultaneously read frequency (Hz) and three amplitude values (acceleration (m/s 2)/velocity (m/s)/displacement (m)) in real time using a tripartite graph ※1.
Additionally, by performing 1/3 octave processing and displaying the VC curve ※2 (Vibration Criterion Curves), it allows for a quick assessment of the allowable vibration standards and installation environment evaluation for vibration-sensitive precision instruments such as AFM, electron microscopes, and laser interferometers.
Unlike conventional methods that require separate differentiation and integration processing for frequency analysis to convert amplitude values, it enables speedy readings of each amplitude value.
※1 The tripartite graph (figure) allows for amplitude readings of acceleration (m/s 2), velocity (m/s), and displacement (m) based on the frequency (Hz) axis.
※2 The VC curve is proposed as a standard for allowable micro-vibrations when installing precision machinery. When using the VC curve, evaluation is conducted in 1/3 octave bandwidth, and the standards are divided into five levels (VC-A, VC-B, VC-C, VC-D, VC-E) in 6 dB increments, serving as guidelines for applications ranging from optical microscopes to long optical path laser devices.

The CF-9200A/CF-9400A features a newly developed front end with 24-bit A/D, achieving a wide dynamic range of over 120 dB. It eliminates the need for changing the voltage range due to A/D over, which was frequently done in normal acoustic and vibration measurements.
There is no longer a need to redo measurements or data records, significantly advancing measurement and analysis work, and allowing beginner users who are unfamiliar with FFT analyzers to use it with confidence.
The CF-9200A/CF-9400A isolates (insulates) all signal input channels.
It has high resistance to ground loops and noise superposition, achieving reliable measurements in measurement sites and targets where potential differences are likely to occur.
Additionally, it protects important systems from FFT signals and sensors that may be exposed to dangerous transient voltages.
The CF-9200A/CF-9400A features a 10.4-inch LCD with a capacitive touch panel.
Gesture operations such as tapping and swiping are adopted for FFT graph manipulation. It has become easy and intuitive to zoom in and out on the desired bandwidth or gain.
Graph scale fitting of waveform amplitude, waveform swapping, zooming in and out on the time axis and frequency axis, waveform offset, and span adjustment can all be done with smooth gesture operations.
The CF-9200A/CF-9400A performs major operations, switching of display data types, and data saving through newly developed large hard key operations from power ON/OFF.
It provides quick and reliable operation even in unstable and narrow spaces, preventing data loss and malfunctions.
Additionally, it is equipped with a lock function (HOLD) for hard keys and touch panels, preventing unintended contact that could lead to malfunctions or setting changes.
The CF-9200A/CF-9400A displays the main operating conditions of the FFT with LED indicators.
From the startup process to the charging status of the built-in secondary battery, and starting with the A/D converter's Over, major hard keys are also equipped with LEDs, allowing the operator to know the operating status of the FFT from a distance.
Automatically detects cable disconnection or connector failure of the accelerometer and microphone ※.
Prevents troubles before the actual measurement.
The CF-9200A/CF-9400A also allows disabling the disconnection detection function.
※ Built-in constant current drive (CCLD) type preamplifier.
By connecting the CF-9200A/CF-9400A to a Windows® PC using a LAN cable, it is possible to copy and write various measurement data, and to operate from the PC side using the remote desktop function ※1, as well as project the screen of the CF-9200A/CF-9400A using a projector.
Additionally, by using the optional LAN external control function (CF-0947), the CF-9200A/CF-9400A can be controlled using a program.
Connection PC requirements: Windows® 10 (32-bit version, 64-bit version)
By attaching a wireless LAN adapter ※2 to the CF-9200A/CF-9400A main unit, you can wirelessly transfer FFT data and record data saved on the CF main unit to a Windows® PC.
Additionally, by using the remote desktop function ※1, you can display the screen and perform remote operations of the CF-9200A/CF-9400A series on a Windows® PC or various portable information devices.
By attaching the short-range wireless communication adapter ※2 to the CF-9200A/CF-9400A main unit, you can wirelessly output the graph on the display screen to a mobile printer ※3 with just the operation of the "PRINT" button on the main unit. You can also connect devices like keyboards wirelessly.
The voltage signals from sensors such as vibrations, noise, distortion, and current probes are converted to A/D and displayed as data in the time axis domain.
With the search cursor, you can directly read the X-axis and Y-axis values of any point, and using the delta cursor function, you can easily read time differences and level differences.
By using the time axis statistical analysis function, quantitative analysis of time waveforms such as mean (MEAN), root mean square (RMS), and crest factor can be performed, as well as abnormal diagnosis.
The power spectrum is obtained by performing FFT analysis to determine the power of each frequency component contained in the captured time-domain waveform, based on the frequency band width (frequency resolution ⊿f), and is graphically represented with frequency on the horizontal axis.
By conducting power spectrum analysis, it is possible to measure vibration noise levels and detect equipment anomalies and natural frequencies of structures that are difficult to estimate with time waveforms alone.
The frequency response function (FRF) represents the ratio of input to output in mechanical or electrical circuits on the frequency axis in terms of gain characteristics and phase characteristics.
The gain characteristic indicates how the amplitude changes as the input signal passes through the transfer system being evaluated, with the Y-axis displayed as the amplitude ratio of output to input.
The phase characteristic shows the lead or lag of the phase between the input and output signals, with the Y-axis displayed in degrees or radians.
The tracking analysis function (CF-0922) automatically saves vibrations and noise generated when various rotating machines operate in low to high-speed ranges while performing FFT, allowing for the analysis of physical phenomena such as vibrations and noise that change with speed based on the rotational speed.
Machines that rotate around an axis, such as engines, gearboxes, turbines, and electric motors, operate over a wide range of speeds from low to high. At specific rotational speeds, components may resonate, causing significant vibrations and noise. To reduce the risk of damage and improve the quietness of the equipment, it is necessary to evaluate the relationship between the rotational speed and the natural frequencies of the components.
By using the tracking analysis function (CF-0922), the relationship between rotational speed and the resulting physical phenomena can be visualized and analyzed from various perspectives, such as color maps, three-dimensional graphs, and harmonic components based on one rotation, allowing for an overview of the specified rotational speed range.
An octave means double the frequency, and because the frequency characteristics perceived by the ear are geometric, octave analysis (CF-0923) is effective for noise analysis.
In the frequency range of the noise to be measured, it is possible to obtain the sound pressure level for each band by passing through bandpass filters specified by the 1/1 octave or 1/3 octave standards.
The Log sweep function continuously varies the frequency of the driving sine wave from the 1ch signal output module (CF-0971), allowing for the evaluation of the resonance point of the target transmission system.
By performing a sine sweep on the frequency axis using a Log scale, it is possible to obtain gain and phase for each frequency, enabling the accurate determination of the response function with a high S/N ratio.
Additionally, the vibration control allows for the control of the amplitude of the vibrator within an arbitrary range during vibration and sweeping, enabling vibration tests to be conducted without considering the frequency characteristics of the electromagnetic vibrator.
* The use of the Log sweep/vibration control function (CF-0942) requires the 1ch signal output module (CF-0971).
