Agilent's handheld spectrum analyzer

Spectrum analyzer is a research instrument electrical signal spectrum structure, measurement signal distortion, modulation, spectral purity and frequency stability and crosstalk and other signal parameters to be used to measure the amplifier and filter circuit systems etc. Some parameter, is a versatile electronic measuring instruments. It may be called a frequency-domain oscilloscope trace oscilloscope, oscilloscope analysis, harmonic analyzer, frequency analyzer or a Fourier analyzer. Modern spectrum analyzers can display the results of the analysis in analog or digital mode, it can be analyzed below 1 Hz VLF to all radio frequency signals submillimeter band. Inside the instrument if digital circuits and microprocessors, with storage and computing capabilities; configuration of standard interfaces, it is easy to form the automatic test system. Spectrum Analyzer is an essential tool for measuring radio signal, is engaged in electronic product development, production, testing of common tools. So, it is widely known as RF engineer multimeter. The large number of companies selling all kinds of spectrum analyzer, price concessions, the full range.
