Aeroflex IFR A-7550 Spectrum Analyzer System 10kHz-1GHz
This listing is for an IFR A-7550 spectrum analyzer from Aeroflex. It has a frequency range of 10kHz to 1GHz and comes in a soft carrying case with several cables. The analyzer was in good working condition when removed from service and is in good cosmetic condition with moderate scuffs. When we plugged it in and turned it on, the screen displayed the IFR logo and then it showed a graph-like screen. We were unable to test it further. This listing has no reserve price so don't miss your chance to win!

Product Description:
IFR Systems (Aeroflex) A-7550 10 kHz to 1 GHz Spectrum Analyzer
The IFR Systems (Aeroflex) A-7550 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 IFR Systems (Aeroflex) A-7550. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for IFR Systems (Aeroflex) A-7550 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 IFR Systems (Aeroflex) A-7550 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 IFR Systems (Aeroflex) A-7550 spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
