System for simple test of the Radio Law and IEEE utilizing a real time spectrum analyzer<\/p>\n\n\n

Application<\/h2>\n

RF transmission characteristic test of equipment with built-in antenna, which is regulated in the technical standard conformity certification and IEEE, can be easily measured combining real time spectrum analyzer MSA500 series and anechoic box. By limiting specifications or applications, it is possible to construct an inexpensive system. <\/p>\n

The physical layer test of ZigBee is regulated in the technical standard conformity certification and IEEE802.15.4-2003.<\/p>\n\n\n\n

      In the measurement of \"spurious radiation strength\" and \"limit on secondary radiated emission\", a spectrum analyzer with 12.5GHz or more bandwidth is required. However, MSA500 series is utilizable if limited by third harmonic (7.4 GHz).

      \"EVM\" and \"frequency carrier error\" can't be measured since the modulation analysis function isn't installed. However, it is possible to observe the raw constellation waveform of Offset-QPSK modulation.<\/p>\n<\/div>\n \n
