Spectrum analyzer

A spectrum analyzer is a measuring device used in electrical measurement technology to record and display a signal in the frequency domain. The display is usually carried out on a screen built into the measuring device, the horizontal axis (abscissa) being the frequency axis and the amplitude being shown on the vertical axis (ordinate). The resulting image is called the frequency spectrum or spectrum for short. In contrast, the measuring device used with a spectrum analyzer, the oscilloscope, shows the signal curve in the time domain. Many digital oscilloscopes now also offer the option of a simple representation of the frequency spectrum.

The spectrum analyzers from Siglent offer a frequency range of up to 7.5 GHZ. The highlight is the new model series SSA3000X-R, which allows the user to perform HF measurements in real time. The SVA1000X series also offers the user a vector network analysis function.
