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 ...

Fast Fourier Transform (FFT) Spectrum Analyzers and Signal Analyzers are instruments used to convert time-domain signals into their frequency-domain representations. They achieve this by digitizing ...

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 ...

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 ...

The bank-of-filters technique is not common in general electronic instrumentation but has been used in some applications, such as low-frequency audio meters (1/3-octave spectrum analyzers). This ...

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 ...

A spectrum analyzer is a device that measures and displays Signal amplitude (strength) as it varies by frequency within its frequency range (spectrum). The frequency appears on the horizontal (X) axis ...

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 ...

RF and EMI engineers spend a great deal of time looking and plots of frequency and amplitude. Depending on the application, you may need a traditional swept spectrum analyzer for continuous signals ...

With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

Spectrum Analyzers are one of the essential RF test and measurement instruments, alongside network analyzers, oscilloscopes, and signal generators. Spectrum Analyzers are one of the most versatile RF ...

APU Spectrum Analyzer is a free spectrum analysis tool supporting a variety of FFT configuration options. You can adjust the FFT window type (Rect, Hann, Hamming, Blackman, Kaiser) and size (from 64 ...
