Impaq's FFT program offers very complete functions that are usually available only from high-end PC based systems. The built-in high-speed DSP chip drives the real-time FFT rate up to 40 kHz, which is even much faster than many PC-based systems currently available today. With impaq, you can perform in-field advanced analysis work without compromise.
Four Channel Cross-channel analysis
Impaq's FFT program allows you to conduct cross-channel analysis. Cross channel analysis functions such as FRF, cross power spectrum and Coherence, which are required for Modal test,ODS test or sound intensity test.
Unlike many handheld analyzers which only perform a "bump test" but can't offer phase information, Impaq has the ability to provide the most complete information that is necessary for advanced analysis.

Waterfall display
This program also supports waterfall measurements, showing continuous spectrum maps over a period of time, or over a rotational speed range.
Once you have a waterfall plot, you may move a slice cursor or a trace cursor to copy and paste the slice data or trace data for detailed investigation.
