Agilent / HP / Keysight 8570A
8570A SPECTRUM ANALYZER
This 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 this unit.
The CRT displays received signal strength (y-axis) against frequency ( x-axis).
