WebLTE transmitter tests are divided into power measurements (transmit power and output power dynamics), signal quality measurements (frequency error and modulation tests (EVM,carrier leakage,spectral flatness) and spectrum measurements (spurious emissions, ACLR, spectrum emission mask,occupied bandwidth). In radio communication, a spurious emission is any component of a radiated radio frequency signal the complete suppression of which would not impair the integrity of the modulation type or the information being transmitted. A radiated signal outside of a transmitter's assigned channel is an example of a spurious emission. Spurious emissions can include harmonic emissions, intermodulation products and frequency conversion products.
WebAccording to §15.407(b) (4) For transmitters operating in the 5.725-5.85 ㎓ band: All emissions within the frequency range from the band edge to 10 ㎒ above or below the band edge shall not exceed an e.i.r.p. of −17 dBm/㎒; for frequencies 10 ㎒ or greater above or below the band edge, emissions shall not exceed an e.i.r.p. of WebThe transmit spectrum mask measurement includes the in-band and out-of-band spurious emissions. It may be expressed as a ratio of power spectral densities (PSD) between the …

Websignals on a frequency not assigned to that transmitter. These signals are called "spurious emissions." FCC regulations concerning spurious emissions are very clear. If interference is caused by spurious emissions, the operator of the transmitter must take whatever steps are necessary to reduce the spurious emissions as required by FCC regulations. tarrega lagrima ukuleleWebIn addition to the emission limits in Table 1, there are restricted frequency ranges, or bands, defined in section 15.205, in which only spurious frequencies may be produced.
