Spectrum Analyzer
See Spectrum Analyzer ProductsA spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals. The input signal that a spectrum analyzer measures is electrical, however, spectral compositions of other signals, such as acoustic pressure waves and optical light waves, can be considered through the use of an appropriate transducer. Optical spectrum analyzers also exist, which use direct optical techniques such as a monochromator to make measurements.

Anritsu
Choose from a family of spectrum analyzers whose measurement capabilities cover frequencies from DC to 40 GHz. Most include built-in one-button measurements that provide the capability to measure occupied bandwidth, channel power, adjacent channel power ratio among other parameters for 2G and 3G wireless communication formats. Included in the family are both bench-top and hand-held battery-operated portable spectrum analyzers.

Keysight Technologies Inc.
Keysight offers an extensive selection of spectrum and signal analyzer products from DC to 50 GHz and extendable to 325 GHz with external mixers. There are two types of spectrum analyzers and the type is dictated by the method used to obtain the spectrum of a signal. A swept-tuned spectrum analyzer uses a superheterodyne receiver to down-convert a portion of the input signal spectrum (using a voltage-controlled oscillator and a mixer) to the center frequency of a band-pass filter. With a superheterodyne architecture, the voltage-controlled oscillator is swept through a range of frequencies, enabling the consideration of the full frequency range of the instrument. A fast Fourier transformation (FFT) analyzer computes the discrete Fourier transform (DFT), a mathematical process that transforms a waveform into the components of its frequency spectrum, of the input signal. Keysight offers swept-tuned and FFT spectrum analyzers, spectrum analyzer software, and spectrum analyzer measurement applications.

SAF North America LLC
Every aspect of SAF's Spectrum Compact series of hand-held spectrum analyzers (300 MHz - 86 GHz) and signal generators (6 GHz - 40 GHz) has been designed with field use in mind, including a resistive touchscreen for operation with gloves, beefy thumbscrews for SMA and waveguide connections, and high-contrast and fill display modes for easy readability in bright light situations. The 8 GB of memory allows you to save thousands of spectrum traces for offline analysis, investigation, and reporting using the included PC software. Spectrum Compact devices are irreplaceable when performing site survey, radio parameter verification, antenna alignment, interference detection, line-of-sight verification and interference hunting.
