Meet Compliance. Master NVH.
Measure with Confidence — Anywhere.
Portable 2- or 4-channel FFT Analyzer for on-site vibration, acoustic, and signal analysis —
trusted by engineers working under FCC Part 15 pre-compliance, NVH, UL 61010, and ISO/IEC testing frameworks.
Portable 2 channel / 4 channel FFT Analyzer — CF-9200A / CF-9400A
All FFT analysis operations can be performed with integrated hard keys and a capacitive touch panel without requiring an external PC. The 100 kHz high-performance analysis front-end with a 24-bit A/D converter enables easier and more reliable analysis of noise and vibration from plant lines, pumps, motors, automobiles, railway vehicles, home electrical appliances and devices, and electrical and electronic parts.
Field work is supported, including resonance and frequency characteristics of mechanical structures in a vibrating environment with electromagnetic vibrators and impulse hammers.
(For teams working under FCC Part 15, NVH, ANSI/UL 61010-1, and ISO/IEC related workflows.)
Built for Compliance and Performance
Basic FFT analysis operations (display, measurement, stopping, recording, readout) can be performed quickly through large hard keys. The touch panel allows intuitive swipe/tap to select the number of waveforms displayed and extend/shorten X and Y axes to the desired scale.
(Usability that supports analysis steps used in NVH and related standards.)
Key Functions & Design
- 24-bit A/D front-end; wide dynamic range (120 dB).
- Efficient calculation and analysis without repeating measuring and recording.
- All signal input channels are isolated (insulated); resistant to ground loops and noise; protection against harmful transient voltages.
- CCLD-equipped inputs and TEDS available; direct connection of accelerometers, charge converter type accelerometers, or microphones; automatic unit calibration to sensor.
- 10.4-inch capacitive touch panel for intuitive pinch/swipe.
- Large hard keys with HOLD lock; highly visible LED indicators for major operations, battery charge, and A/D oversampling.
- Cable disconnection detecting function for accelerometer and microphone (built-in preamplifier CCLD type).
(Supports FFT analysis steps used in FCC Part 15 pre-analysis, NVH, ANSI/UL 61010-1, and ISO/IEC-related evaluations.)
