Agilent 8561E Portable Spectrum Analyzer 30 Hz to 6.5 GHz
The Agilent 8561E 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 8561E. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Agilent 8561E 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 Agilent 8561E 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 Agilent 8561E spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
The Agilent 8561E portable RF spectrum analyzer offers the measurement capability and performance previously found in larger, more expensive benchtop analyzers. This analyzer combines outstanding phase noise, sensitivity, 1 Hz resolution bandwidths, synthesized tuning and wide dynamic range in a MIL-rugged package built to withstand harsh environmental conditions. It offers a complete solution for adjacent-channel power (ACP) testing of burst carrier signals using digital modulation, and the ability to measure occupied bandwidth percentage.
Time-gated signal analysis allows you to easily measure time-varying signals such as pulsed RF, time-division multiple access, interleaved, and burst-modulated. For millimeter applications that don''t require full microwave coverage, the Agilent 8561E with the Agilent 11970 series harmonic mixers or Agilent 11974 series preselected mixers is a lower-cost solution.
