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 Anritsu MSB. The CRT displays received signal strength y-axis against frequency x-axis. Interference: Before a system is installed you use a Anritsu MSB 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 Anritsu MSB spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components. Anritsu History Anritsu is a leading manufacturer of radiofrequency RF test equipment and communications devices.
The enlarged company then turned its attention to developing transmission systems for emerging television technology. By , Anritsu succeeded in building its first television broadcast transmitter. While Anritsu continued developing telephone systems, the company expanded its testing and measuring operations. Anritsu went public in , listing on the Tokyo Stock Exchange.
The listing enabled the company to expand beyond Japan for the first time, and in it began exporting its public telephones to Australia. The addition of Wiltron, which was especially strong in the midrange-frequency sector, Anritsu positioned itself early on to capture a central position in both its domestic market and in the United States.
In Europe, the company opened a new European Measurement division in the UK in order to develop and manufacture test and measurement systems specifically for the European market.
By the end of the decade, Anritsu was present in more than 50 countries worldwide, with sales topping 1 billion USD. Nonetheless, Anritsu's strong commitment to research and development had kept the company at the forefront of the industry. As the telecommunications market began to bounce back, with the advent of third-generation mobile telephone technology, Anritsu's product development promised to keep it as a leading figure on the global scene.

Anritsu MS2651b Spectrum Analyzer help
QRZ Forums. I have recently aquired an analyser with a failed display, it appears that the issue is on the AO3 CPU board but unfortunately no service data or schematics are available for this particular model and Anritsu themselves were only able to supply user manuals which only go as deep as block diagrams. If there is any one out there that can assist with any technical documentation it would be very much appreciated. It would be a real shame to strip the unit for parts as it appears to be fully functional from an RF point of view and is in excellent cosmetic condition. M0KRL , Jun 11,
