(a) For field strength measurements: ----------------------------------------------------------------------------------------------------------------
Range of frequency measurementsFrequency band in which device operates ------------------------------------------------------------------------
(MHz) Lowest frequency Highest frequency----------------------------------------------------------------------------------------------------------------Below 1.705............................ Lowest frequency generated in the 30 MHz.
device, but not lower than 9 kHz.1.705 to 30............................ Lowest frequency generated in the 400 MHz.
device, but not lower than 9 kHz.30 to 500.............................. Lowest frequency generated in the Tenth harmonic or 1,000 MHz,
device or 25 MHz, whichever is whichever is higher.
lower.500 to 1,000........................... Lowest frequency generated in the Tenth harmonic.
device or 100 MHz, whichever is
lower.Above 1,000............................ ......do........................... Tenth harmonic or highest
detectable emission.----------------------------------------------------------------------------------------------------------------
(b) For conducted powerline measurements, the frequency range over which the limits are specified will be scanned. [50 FR 36070, Sept. 5, 1985, as amended at 51 FR 17971, May 16 1986]
