HP-STAP ZoomFFT Analysis Software delivers high-resolution spectrum analysis within a selected frequency band. By focusing FFT computation on a narrow range, Zoom FFT provides much finer frequency resolution than a full-band FFT—making it ideal for closely spaced tones, small frequency shifts, and weak spectral components.
| Higher frequency resolution where it matters | ZoomFFT improves resolution in the selected band compared to full-band FFT |
|---|---|
| Narrowband “spectral magnification” | Makes small frequency shifts and close peaks easier to separate |
| Better weak-signal visibility | Helps reveal low-amplitude components hidden near strong tones |
| Broad applicability | Useful across many fields that require fine spectral inspection and verification |
| Faster troubleshooting | Quickly confirm whether peaks are distinct or overlapping in a critical band |
Series: HP-STAP
Product Type: Zoom FFT (ZoomFFT) analysis software
Core Capability: High-resolution FFT within a user-selected frequency range
Best For: Narrowband spectrum inspection and detailed frequency-domain amplification
Key Advantage: Higher frequency resolution inside the chosen band than standard full-spectrum FFT
A standard FFT spreads your frequency resolution across the entire bandwidth. When you need to inspect a specific region—such as a resonance band, a harmonic cluster, or a small shift around a fault frequency—full-band FFT can look “too coarse.” HP-STAP ZoomFFT focuses computation on the band of interest, effectively giving you a magnified, narrowband spectrum with finer detail for diagnosis and verification.
Rotating machinery diagnostics: separating close harmonics or sidebands
Detecting small frequency drift or modulation effects
Resonance investigations in a narrow frequency window
Electrical/acoustic tone analysis where peaks cluster tightly
R&D validation and quality checks requiring precise frequency measurement
(Kept general to avoid adding specs not shown in the image.)
Works with time-domain signals used for frequency-domain analysis (e.g., vibration, acoustic, or other measured waveforms)
Suitable for workflows that require narrowband spectral zoom and verification
(Based strictly on the image’s feature description—no invented numeric ranges.)
ZoomFFT narrowband selection: focus on a specific frequency range
High-resolution spectrum output: increased frequency resolution within the selected band
Narrowband spectral amplification: detailed inspection of the target band for analysis and validation
Q1: What is Zoom FFT (ZoomFFT)?
ZoomFFT is a narrowband FFT method that provides higher resolution within a selected frequency range than a standard full-band FFT.
Q2: Why would I use ZoomFFT instead of a normal FFT?
Use it when you need fine detail in a specific band—such as separating close peaks, observing small frequency shifts, or identifying weak components.
Q3: Does ZoomFFT change the signal, or just the analysis?
It changes the analysis focus by concentrating resolution in the chosen frequency range, effectively providing a “zoomed-in” spectrum view.
Q4: When is high-resolution narrowband analysis most helpful?
When spectral components are closely spaced, when there’s drift/modulation, or when you must verify exact peak locations in a limited band.
Q5: Is ZoomFFT only for vibration?
No. Any field that needs precise narrowband frequency analysis can benefit, including acoustics and other signal analysis applications.
