This audio spectrum analyzer utilizes an ARM7 LPC2138 microcontroller to create an FFT algorithm while performing digital signal processing without the use of special DSP processor. This audio ...

RF signal observation has evolved from yesteryear’s spectrum analyzer to today’s RF recorder. Swept spectrum analyzers, FFT analyzers, and real-time signal analyzers all had limitations. Today’s RF ...

Audio Precision has improved the bandwidth of the FFTs (fast Fourier transforms) in its APx52X audio analyzers from 90 kHz to 1 MHz. The BW52 option provides a frequency resolution of 2.5 Hz at the ...

While high-fidelity audio has come a long way in the past several decades, a lot of modern stereo equipment is still missing out on some of the old analog meters that were common on amplifiers and ...

The Compact Spectrum Analyzer (CSA) from MPB srl of Italy is a real-time FFT handheld spectrum analyzer. It features a 7-inch color touchscreen and coverage of spectrum from 10 Hz to 4 GHz. It ...

No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...

VIBXPERT EX, the new two-channel FFT data collector and signal analyzer from LUDECA Inc. monitors and diagnoses machine conditions for potentially hazardous environments that require explosion-proof ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...

Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...
