Rohde & Schwarz, Inc. FSEM30 26.5GHz, Spectrum Analyzer
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...
