Product Description:
Advantest R3162 Spectrum Analyzer(New, Advanced Info)
The Advantest R3162 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 R3162. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Advantest R3162 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 R3162 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 R3162 spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
Basic functions are reinforced so that R3162 can be used in various fields. For example, the internal automatic calibration function guarantees the total level accuracy of ±1.5dB, level correction factor can be stored in the internal memory, DDS is employed to improve frequency reading accuracy, and frequency span error is lowered to less than 1%. The R3162 offer wider dynamic range and lower 2nd and 3rd distortion by improving 1dB compression point. As a result of increasing the sweep repetition cycles by improving the synthesized local scillator, 20 traces/second (typ.) data rewriting becomes possible, enabling far more real-time waveform measurement. high speed GPIB increase, the throughput of automatic measurement.
