A spectrum analyzer is an essential instrument for RF and microwave circuit design. However, at first glance it seems to be an odd choice for analyzing high speed serial data channels. This article ...

Modern wireless communications are using increasingly wide bandwidth-modulation schemes, and packet communications are getting faster. Transmissions are increasingly time-varying. Radios often ...

It also can coherently map a broadband laser spectrum into the RF domain. The VSA features a bandwidth of 55.1 THz (1260 to 1640 nm), frequency resolution of 471 kHz, and dynamic range of 56 dB.

Finisar Corporation FNSR recently announced that it has introduced WaveAnalyzer 1500S/L High Resolution Optical Spectrum Analyzer. The instrument is designed to inspect the spectral characteristics of ...

No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...

The RF signal analyzer is one of the most versatile tools on the RF test bench, allowing engineers to measure signals ranging from electromagnetic emissions to wireless communications. Most frequently ...

SUNNYVALE, Calif., Sept. 03, 2019 (GLOBE NEWSWIRE) -- Finisar (NASDAQ: FNSR) today introduced its WaveAnalyzer™ 1500S/L High Resolution Optical Spectrum Analyzer designed to inspect the spectral ...

Back in the 1960s, when I started working in radio broadcast engineering, an oscilloscope was my “eye” on what was happening with equipment. That tool served me well and is still in daily use in my ...

A hardware device or software used to examine the frequency and power components of a signal. It provides more information than an oscilloscope, because it can display the signals over a range of ...

Maintaining a wireless network in a business environment can be a royal pain in the neck. Just because your wireless network worked flawlessly yesterday, doesn't mean that some new and unknown ...
