Intuitive Button and Touch-panel Operations
The CF-7200A needs no mouse - simply press buttons for all operations. The clickfeel buttons and touch panel allow immediate operations ranging from start/stop of analysis to display of basic functions.
Lightweight, Compact and Highly Portable for All Sites
No setup needed before measurement or troublesome installation on site, such as connecting a personal computer, cables, and power supply to a measuring instrument. All functions necessary for measuring and analyzing noise and vibration are built into the CF- 7200's small file size, for greater flexibility on all sites.
Thanks to the 10.4- inch TFT liquid crystal display, detailed data can be displayed even though QUAD display mode is selected. Simple and easy operation is also possible by touch panel.
With the supplied stylus pen, comments, marks and memos can be entered directly, making it easier to recognize the working efficiency and data. Memos can be saved simultaneously and be shown or hidden.
Selection of main data of the FFT analyzer, selection of the input voltage range and frequency range, and saving and loading of data can be performed directly from the hardware keys on the front panel. The CF-7200A offers simple, quick operations and much more. Even when observing a signal with unknown magnitude and frequency, an appropriate range and display conditions can be set with intuitive continuous button operations. And the signal output function can be turned on or off with the hardware keys, so signal output (option) can be started or stopped with a simple ON/OFF, preventing careless operations.
Each channel is equipped with a CCLD (power supply for sensors) which can directly drive an accelerometer, a microphone, and other sensors requiring a power supply. TEDS reads data retained in a TEDS sensor and then automatically supplies the power to the sensor and performs unit calibration.
Can be operated under the condition of noise/vibration-free up to about 5 minutes by means of cooling fan off. Since the CF-7200A itself would not be the source of noise/vibration, analyzing or collecting for subtle noise/vibration is easy without worrying about self-noise/vibration.
Automatically detects cable disconnection of an accelerometer and a microphone*, preventing trouble before measurement.
* Intended for sensors with a built-in constantcurrent type preamplifier.
Equipped with dedicated connectors which directly drive a rotation detectors (Applicable to the MP-981/LG-916) and can be used as an external sampling clock. This makes it easy to perform order ratio analysis (CF-0722 tracking analysis option) which analyzes vibration and noise of engines, motors, and other rotating machinery with rotation-based values.
When the remote controller (DS-0295 option) is connected to the CF-7200A, three main operations can be performed in addition to analysis start/stop. Operating the CF- 7200 from near the working or supervising position makes measurement much easier.
A signal coming from an acoustic or vibration sensor connected to each channel can directly be monitored as sound using a headphone or an external speaker. It makes possible to check aurally whether an intended vibration or sound is input correctly as well as by waveform observation, allowing you to check sensor setup and operation intuitively and with your senses.

The DAT format (binary), TXT format and BMP format can also be saved simultaneously. Data can also be processed using office software and pasted into reports. Since the underlying data in DAT format are securely saved, data can be displayed and processed using PCbased FFT software (DS-2000/3000 Series, XN-8000 Series, or OC-1300 series) and the CF unit.

Report Creation software
Graph Creation Tool
The USB mass-storage function makes it possible to transfer data of the CF-7200A to a PC through a USB cable* without having to remove a storage medium and without needing special software (Windows ® 2000/XP).
A raw signal coming from an acoustic or vibration sensor connected to each channel can directly be monitored as sound using a headphone or an external speaker. This makes it possible to check aurally whether an intended vibration or sound is input correctly as well as by waveform observation, allowing you to check sensor setup and operation intuitively and with your senses.
Equipped with a built-in microphone for voice recording and a speaker, voice memos can be attached to data and played back when the data is displayed, supporting data arrangements.
New Possibilities for Measurement and Analysis, from Laboratories to Production Sites
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 Xand 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 power spectrum indicates the magnitude of frequency components contained in a sampled time-axis waveform. Frequency 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 timeaxis waveform. The natural frequency of a structure can also be measured.
Frequency Response Function
The frequency response function indicates the ratio of output to input and the frequency characteristics of phase difference. The resonant frequency and phase of a structure can easily be obtained accurately by entering the signal of vibration force generated to Ch1 by an impulse hammer or shaker and then inputting the response (signal of acceleration, velocity and displacement) to Ch2.
The coherence function is for evaluating the linearity and correlation of input and output of a transmission system, obtained in the frequency domain. The rate of contribution of the input signal to the output signal is represented as a digit from 0 to 1 for each frequency, for evaluating the reliability of the frequency response function, locating a key factor from multiple noise and vibration sources, and evaluating the correlation.
Inverse Fast Fourier Transform (IFFT)
After frequency analysis, a time-axis waveform of a selected band can be obtained again by performing Inverse Fast Fourier Transform (IFFT) for the selected frequency band. For example, by selecting a waveform portion excluding an unnecessary frequency band confirmed in the FFT result and then performing Inverse Fast Fourier Transform (IFFT) for it, a time-axis waveform can be obtained with the selected high frequency band eliminated.
A logarithmic damping factor can be obtained by obtaining a time envelope of a time-axis signal by means of Hilbert transform.
Cepstrum is obtained by performing Fourier transform of the power spectrum again, allowing detection of the periodicity contained in the spectrum. In addition, reflected waveforms can be eliminated and fundamental frequency extracted by estimating a spectrum envelope from the Cepstrum. Cepstrum can be applied to make an analysis of the sound waves, seismic waves, biowaves, etc.
Tracking analysis (option:CF-0722)
Tracking analysis is effective for analyzing the noise and vibration in synchronization with rotational speed. This function enables analysis which rotational speeds increase noise and vibration, which rotating parts cause this noise and vibration, and how many times of the frequency component of noise and vibration to the rotational speed occur.
■Constant width tracking
Rotational tracking analysis (option:CF-0722)
Equipments with built-in rotating machines, such as engines and motors in products like automobiles and office equipments, may have serious problem when the resonance between rotational equipment of rotating machine and each components will occur. This rotational tracking analysis helps greatly in cases like this.
Multiple Applications with a Single CF-7200A
The CF-7200A FFT analyzer can not only directly read values as a voltage (V) but also as a physical quantity. When the input sensitivity has been set and calibration with a reference signal performed for each sensor, waveform values are converted to physical quantities when displayed, eliminating the need to convert from voltage values to physical quantities.
Average Summation UNDO Function
This function is used during average summation to UNDO one average summation. For example, if you end up with a bad result of summation in impulse hammer shaking, you can cancel the result data (by UNDOing the summation) and then try the summation again.
Differential and Integral Functions
First and second order differential operations and single and double integral operations are possible for time-axis and frequency-axis waveforms. Acceleration data from an acceleration sensor can be converted to velocity and displacement; and velocity data from a laser Doppler vibration meter can be converted to acceleration and displacement and displayed. When the EU function is used together, unit conversion (among "m/s2", "m/s" and "m") is also performed automatically.
This function displays a list of X-axis and Y-axis values for selected points on a displayed waveform. Numeric list for 40 points selected, peak value list and harmonic list enable numeric values to be simultaneously checked for multiple points.
