The Keysight E4411B ESA-L Spectrum Analyzer, 1 MHz to 1.5 GHz (75-ohm)
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 Agilent Technologies E4411B. The CRT displays received signal strength (y-axis) against frequency (x-axis).
