Anritsu Corporation has extended its signal analyser MS2840A product line by adding three new frequency models – 3.6 GHz, 6 GHz and 26.5 GHz – to its existing 44.5 GHz model. According to the company, the new models offer excellent close-in single side-band (SSB) phase noise performance that exceeds the performance of other high-end models. Further, the SSB phase noise performance upgrade has sufficient margin for evaluating the spurious and phase noise of oscillators in wired and wireless equipment, which could earlier be evaluated using large and expensive dedicated phase noise measuring instruments and spectrum analysers. The new models are suitable for wireless equipment and electronic parts manufacturers engaged in private mobile radio communications, wireless backhaul, radar, satellite communications, automobile electronics, etc.
Another key advantage of the new signal analyser is that it offers support for millimetre-waveband transmitter and antenna measurements. As per the company, connecting the high performance waveguide mixer (50-90 GHz) for millimetre-waveband measurement to either the 26.5 GHz or 44.5 GHz model not only supports wide-dynamic-range measurements but also eliminates image-response effects when measuring wideband signals. This enables efficient measurement of millimetre-wave wideband wireless equipment such as wireless backhaul and automobile radar, as well as the evaluation of side-lobe characteristics of millimetre-wave band radar antennas, which require high sensitivity.
Further, the MS2840A platform has built-in functions for the efficient measurement of Tx characteristics, including spurious, adjacent channel leakage power, spectrum mask and frequency count. The built-in signal analyser functions also support power versus time, frequency versus time, phase versus time, and spectrogram measurements. Moreover, the standard measurement functions can be extended by installing vector modulation analysis software, analog measurement software, noise figure measurement functions, etc. A signal generator can be installed in the 3.6 GHz and 6 GHz models to direct the digital and analog modulation signals required for evaluating wireless TRx signals using a single MS2840A set.
