47 CFR 18.309 - Frequency range of measurements.
|Frequency band in which device operates (MHz)||Range of frequency measurements|
|Lowest frequency||Highest frequency|
|Below 1.705||Lowest frequency generated in the device, but not lower than 9 kHz||30 MHz.|
|1.705 to 30||Lowest frequency generated in the device, but not lower than 9 kHz||400 MHz.|
|30 to 500||Lowest frequency generated in the device or 25 MHz, whichever is lower||Tenth harmonic or 1,000 MHz, whichever is higher.|
|500 to 1,000||Lowest frequency generated in the device or 100 MHz, whichever is lower||Tenth harmonic.|
|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.
