Ofdm Spectrum Analyzer
As a measurement example fig.
Ofdm spectrum analyzer. High resolution optical spectrum analyzer osa 21 02 2013. A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. When the signal is noiselike peak measurements are a very useful indication of spectrum occupancy but generally not ideal for measuring an. The primary use is to measure the power of the spectrum of known and unknown signals.
This paper shows the great utility of our high resolution optical spectrum analyzer ap2040 ap2050 series in demonstrating a 23 6 gb s optical orthogonal freqency division multiplexing ofdm 20 gb s after coding with a colorless transmitter realized by optical iq. The input signal that most common spectrum analyzers measure is electrical. The r s fs k96pc ofdm analysis software extends the capability of the r s fsq fsg fsv fsvr fsw signal and spectrum analyzers and the r s fsup signal source analyzer to include modulation measurements on general ofdm signals. Tg44a 4 4 ghz tracking generator 655 usd.
Moreover the ms2687b has a maximum rbw of 20 mhz and is ideal for measuring the burst power of wideband signals used by wireless lans. There are several different types of spectrum analyzer that can be bought and used. Ofdm signal spectrum and to display all the sub carriers clearly even with a. Performance and cost can be balanced to give the best option for any application.
The ofdm demodulator is user configurable and standard independent. See our sna combos rf test accessories. Each type has its own characteristics. By purchasing a tracking generator with an sa or bb series spectrum analyzer you can create a scalar network analyzer sna and save 3.
Ofdm channel sc qam channels. The r s fs k96 ofdm analysis software extends the capability of the r s fsq fsg fsv fsvr fsw signal and spectrum analyzers and the r s fsup signal source analyzer to include modulation measurements on general ofdm signals. There is urgent need for ofdm signal analysis. The ofdm demodulator is user configurable and standard independent.
In other words the heights of the ofdm and sc qam haystacks as seen on a spectrum analyzer should be the same. The ms2687b microwave spectrum analyzer covers a frequency range up to 30 ghz and can measure up to 5th order harmonics on 5 ghz wireless lans. There are several key topics that are associated with rf spectrum analyzers and their use. Ofdm channel power signal level in most cases ofdm channel power should be set to the same power spectral density psd as sc qam signals.
Optical ofdm orthogonal frequency division multiplexing is a. 2 a perfect tool for optical ofdm. See all signal generators. However spectral compositions of other signals such as acoustic pressure waves and optical light waves.
High resolution optical spectrum analyzer used for experimental demonstration of 23 6 gb s ofdm with a colorless transmitter.
