Our field, fixed and bench spectrum analyzers are engineered for professional performance and are used in test, development and manufacturing processes. Our inventory of analyzers display the spectrum of audio or radio frequency signals. They show signal amplitude on a vertical axis in relation to frequency on the horizontal axis. The top spectrum analyzer manufacturers, such as Keysight Technologies and Rigol, build accurate units that deliver highly reliable readings. They offer instruments for RF analysis that are valuable during maintenance, production, education and communication applications. Within our analyzer selection, we supply devices that work for a variety of industries, from wireless communications to aerospace.
