Sec.  18.309   Frequency range of measurements.

   (a) For field strength measurements:


-------------------------------------------------------------------------------
---------------------------------
                                                             Range of frequency
 measurements
Frequency band in which device operates ---------------------------------------
---------------------------------
                 (MHz)                             Lowest frequency
        Highest frequency
-------------------------------------------------------------------------------
---------------------------------
Below 1.705............................  Lowest frequency generated in the    3
0 MHz.
                                          device, but not lower than 9 kHz.
1.705 to 30............................  Lowest frequency generated in the    4
00 MHz.
                                          device, but not lower than 9 kHz.
30 to 500..............................  Lowest frequency generated in the    T
enth harmonic or 1,000 MHz,
                                          device or 25 MHz, whichever is
whichever is higher.
                                          lower.
500 to 1,000...........................  Lowest frequency generated in the    T
enth harmonic.
                                          device or 100 MHz, whichever is
                                          lower.
Above 1,000............................  ......do...........................  T
enth harmonic or highest

detectable emission.
-------------------------------------------------------------------------------
---------------------------------

   (b) For conducted powerline measurements, the frequency range over which the
   limits are specified will be scanned.
