友情提示--EN 300 328 V1.4.1 /V1.5.1 /V1.6.1之差異

  前R&TTE 所公佈之Harmorized Standard中的EN 300 328 V1.4.1 /V1.5.1 /V1.6.1都可使用,
        而 EN 300 328 V1.6.1與EN 300 328 V1.4.1之版本如下:
       
        1. 5.7.2 Effective radiated power(5.7.2 Equivalent isotropic radiated power-EN 300 328 V1.6.1):
           在EN 300 328 V1.6.1版本中Peak Power之部分無限制且不需測試,只需要測試Average Power,因此此項之部分
           對於IEEE 802.11G(OFDM)之部分較為寬鬆,功率值不受到Peak Power(23dBm)限制而無法調高功率(OFDM之Peak與  
           Average之功率差為6-8dB之間)
         
        2. 5.7.3 Maximum spectral power density:
           在EN 300 328 V1.6.1版本中測試之設定與EN 300 328 V1.4.1及EN 300 328 V1.5.1有所不同如下所示:
          
            EN 300 328 V.1.6.1中無定義RBW設定為 DSSS(OFDM)or FHSS都為1MHz如下所示(更正與之前法規相同為100kHz):
           centre frequency: equal to the signal source;

         resolution BW: 1 MHz;

         video BW: same;

         detector mode: positive peak;

         averaging: off;

         span: zero Hz;

         amplitude: adjust for middle of the instrument's range.
          
            EN 300 328 V1.4.1及EN 300 328 V1.5.1之設定如下:
             
          centre frequency: equal to the signal source;

         resolution BW: 100 kHz for FHSS, 1 MHz for DSSS;

         video BW: same;

         detector mode: positive peak;

         averaging: off;

         span: zero Hz;

         amplitude: adjust for middle of the instrument's range.
       
         3.5.7.5 Transmitter spurious emissions
           5.7.6 Receiver spurious emissions
           在EN 300 328 V1.6.1版本中測試之設定與EN 300 328 V1.4.1有所不同如下所示:
           - resolution BW: 100 kHz;
          - video BW: 30 KHz;
          - detector mode: positive peak;
          - averaging: off;
          - span: 100 MHz;
          - amplitude: adjust for middle of the instrument's range;
          - sweep time: 1 s.
            
           EN 300 328 V1.4.1之設定如下:

           resolution BW: 100 kHz;
         - video BW: same;
         - detector mode: positive peak;
         - averaging: off;
         - span: 100 MHz;
         - amplitude: adjust for middle of the instrument's range;
         - sweep time: 1 s.
       
       4. 4.2.1 FHSS Modulation:
             
            在EN 300 328 V1.6.1之版本中對於FHSS之部分有AFH(Adaptive Frequency hopping)之功能,針對
            Channel之要求如下所示:
          
          or if capable of adaptive frequency hopping:
          b) at least be capable of operating over a minimum of 90 % of the band specified in table 1,    from which at any given time a minimum of 20 channels or hopping positions shall be used.
For both cases, the minimum channel separation shall be 1 MHz, while the dwell time per channel shall not exceed 0,4 s.
