Spectral Analyser

A spectrum analyzer is a measuring instrument that displays the frequencies present in a signal, as well as their amplitude. It is used to observe signals, and more specifically their frequency components. The analyzer displays signal amplitude on the vertical axis and frequency on the horizontal axis. Numerous signals can be detected with a spectrum analyzer, including analog, digital, and RF signals.

Spectrum analyzers meet the requirements of high-frequency engineering and are widely used in radio frequency, wireless, and telecommunications applications. By examining a signal's spectrum, analyzers can reveal signal components and the performance of the circuit that generates them. It has become an essential tool in RF design test and development laboratories. A spectrum analyzer is crucial for designing, testing, and maintaining radiofrequency equipment and circuits. They are also becoming increasingly important in higher education. Typically, they include a digital screen for visualizing results and a control interface for configuring the analyzer.

We offer two types of spectrum analyzers: benchtop and portable models. Benchtop analyzers are primarily used in R&D workshops, whereas portable analyzers are more compact, making them easier to transport on a daily basis. Our selection of portable spectrum analyzers includes models from the leading brand Aaronia. Our benchtop analyzer range includes reputable brands such as Rigol, Siglent, and Tektronix.

Our advice? Choose the spectrum analyzer that fits your needs based on these four criteria: bandwidth, maximum and minimum frequency, frequency stability, and screen size.

To meet all needs, several types of spectrum analyzers are available:

Swept-tuned spectrum analyzer: These are the most common models. They sweep a frequency range to reveal existing signals and their relative intensity. These devices are ideal for a wide variety of uses, including detecting RF interference and identifying unwanted signals in a specific spectrum.
FFT (Fast Fourier Transform) analyzer: FFT analyzers convert analog signals into digital data for detailed analysis. Their accuracy and speed are particularly beneficial in fields where precise signal evaluation is required. While generally more expensive than standard analyzers, their outstanding performance makes them essential for specific applications.
Real-time spectrum analyzer: These analyzers offer immediate evaluation thanks to extended buffer memories and high-performance processors. They are designed to detect transient or sporadic signals with high accuracy, making them ideal for environments requiring fast and precise measurements.
Audio spectrum analyzers: Focused on low frequencies, these devices are ideal for audio signals. They are typically more affordable than their RF counterparts while being perfectly suited for professional audio applications, such as sound quality analysis or assessment of sound systems.
