Speedy

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

With the CF-9000A 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-9000A series, the two on-board, large-capacity lithium ion secondary batteries enable continuous cordless operation of up to 8 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.

*2 Full recharge takes 7 or 8 hours depending on operating conditions.

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-9000A 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-9000A 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*.

Real-Time Tripartite Graph & VC Curves Display for Precision Vibration Evaluation

The CF-9200A / CF-9400A FFT Analyzer features an advanced real-time tripartite graph display, enabling simultaneous visualization of acceleration, velocity, and displacement during FFT analysis.

Unlike conventional FFT analyzers that require manual differentiation or integration, this function allows engineers to read vibration amplitude instantly at any frequency, significantly reducing analysis time and improving workflow efficiency.

After 1/3-octave band processing, the analyzer displays Vibration Criterion (VC) Curves, making it easy to evaluate whether a vibration environment meets allowable limits for vibration-sensitive precision instruments, including:

• Atomic Force Microscopes (AFM)

• Electron Microscopes (SEM / TEM)

• Laser interferometers

• Optical and semiconductor inspection systems

VC levels (VC-A to VC-E, 6 dB increments) provide a clear reference for research facilities, cleanrooms, and high-precision laboratories.

Wide Dynamic Range FFT Analyzer with 24-bit A/D Front End

The CF-9000A series employs a 24-bit A/D front-end system, delivering an exceptional 120 dB dynamic range.

This eliminates the need for frequent voltage range switching during oversampling, a common challenge in acoustic and vibration measurements. As a result:

• Measurements do not need to be repeated

• FFT analysis becomes faster and more reliable

• Even novice users can perform accurate vibration analysis with confidence

Fully Isolated Inputs for Noise-Free and Reliable Measurements

All input channels are fully isolated, providing excellent resistance to ground loops, electrical noise, and potential differences.

This isolation architecture:

• Ensures stable vibration data in harsh electrical environments

• Protects FFT system components from transient voltages

• Enhances measurement reliability in industrial and research sites

CCLD and TEDS Support for Accelerometers and Microphones

Each input channel is equipped with CCLD (Constant Current Line Drive), allowing direct connection of accelerometers and microphones without external amplifiers.

In addition, TEDS-compatible sensors enable:

• Automatic sensor recognition

• Automatic power supply and calibration

• Reduced setup time and prevention of configuration errors

This makes the CF-9000A series ideal for multi-sensor vibration measurement systems in R&D and production environments.

Intuitive Touch Panel Interface for FFT Analysis

The analyzer features a 10.4-inch capacitive touch panel, supporting intuitive pinch and swipe gestures for FFT graph manipulation.

Users can quickly:

• Zoom frequency bands

• Adjust gain settings

• Navigate complex FFT data visually

This UI design significantly improves usability during on-site vibration diagnostics.

Hard Keys and LED Indicators for Reliable Field Operation

Large, tactile hard keys ensure reliable operation in:

• Dark environments

• Unstable field locations

• Industrial testing sites

Key functions such as power, data type selection, and data saving are clearly separated to prevent operational errors.
LED indicators provide instant visibility of system status, including battery charge, FFT operation, and oversampling activity — even from a distance.
