Rohde & Schwarz FSEM30 20Hz - 26.5GHz Spectrum Analyzer w/ Opts B4 & B5 - CAL'D

Rohde & Schwarz FSEM30 20Hz - 26.5GHz Spectrum Analyzer with Options B4 & B5 - CALIBRATED!


You are bidding on a Rohde & Schwarz FSEM 30 Spectrum Analyzer 20Hz - 26.5 Ghz with options B4 (Low Phase Noise) and B5 (FFT Filter, Bandwith 1 Hz - 1 kHz).  It will arrive with a current calibration performed by an ISO 17025 accredited lab.

The Rohde & Schwarz, Inc. FSEM30 spectrum analyzer is a wide band, very sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Rohde & Schwarz, Inc. FSEM30. The CRT displays received signal strength (y-axis) against frequency ( x-axis).

Some applications for Rohde & Schwarz, Inc. FSEM30 Spectrum Analyzers include Site Monitoring: Verify that the frequency and signal strength of your transmitter is accurate. Interference: Before a system is installed you use a Rohde & Schwarz, Inc. FSEM30 spectrum analyzer to verify that the frequencies (you plan to use) are not occupied or if the presence of a very strong signal will interfere with your new setup. Interference can be created by a number of different situations. Other tests that utilize the Rohde & Schwarz, Inc. FSEM30 spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
