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 ...

Modern pulsed radar systems use advanced waveform and modulation characteristics to obtain greater range resolution, enhanced clutter suppression and superior target recognition. Specifically, ...

Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...

The Zoom FFT is interesting because it blends complex down conversion, lowpass filtering, and sample rate change through decimation in a spectrum analysis application. The Zoom FFT method of spectrum ...

The Rigol DS1000 series of oscilloscopes are popular with hobbyists for good reason: they provide decent specs at a low price. However, their spectrum analysis abilities are lacking. While these ...

EE’s electronic test instrument coverage achieved critical mass in the mid-1980s, including a spectrum analyzer story in the August 1986 issue and subsequent August issues into the 1990s and beyond.

RIGOL Technologies introduces the new RSA5000 real-time spectrum analyzers to complement the DSA800-TG family of low-cost spectrum analyzers. The devices are based on the new Rigol-developed ...

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 ...

In the not-so-distant past, contractors and consultants who wanted to check parameters at a number of FM stations had to lug around a frequency-agile FM monitor and related gear. Today, DSP technology ...

The VSA-1225 vibration spectrum analyzer (VSA) is a PDA-based vibration analyzer-data collector. It’s on the Windows Mobile/Pocket PC platform. It includes version 1.8 of the company’s Spectrum ...
