Product Description:
Advantest R9211B FFT Servo Spectrum Analyzer
The Advantest R9211B 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 Advantest R9211B. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Advantest R9211B 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 Advantest R9211B 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 Advantest R9211B spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
Feature:Minimum Frequency: 10mHz
Maximum Frequency: 100kHz
The R9211B has a signal generator and is ideal for component oscillation analysis or measurement of servo circuits. It continues the servo measurement know-how employed in previous modes, using ADVANTEST's exclusive SSS (Swept Sine Sweep) technique. It realizes a maximum amplitude difference of +/-0.1 dB between channels and maximum phase difference of +/-1.0 degrees between channels.
It has a built-in summation amplifier for use in open loop characteristics evaluations; low SG output impedance; and a servo measurement function using a log frequency table, making it ideal for use in servo design and development. There has been a great improvement in operability and reduction in measurement time over previous models. There is an optional digital signal generator output and a feature allowing analysis by digital input. Also, new applications and the servo analysis mode have been added so that measurement can be done in 5 domains.
