The proposed method mainly depends on spectrum emission
mask (SEM) technique to investigate different interference scenarios such as co-channel, adjacent channel with overlapping band (Overlp_B), with zero guard band (ZGB), or with guard band (GB), for different bandwidths of the interferer and victim.
The spectrum analyzer measures spurious emissions of a mobile radio base station using the spectrum emission
mask (SEM) function.
Built-in functions include channel and multichannel power, pulsed measurement, gated sweep, occupied bandwidth, spectrum emission
mask, TOI measurement, total harmonic distortion, AM/FM and digital demodulation analysis, X-dB down, and phase noise measurement.
These packages not only include all the standard-compliant settings for measurements of in-band parameters such as modulation accuracy, frequency error or performance of power control, but also the correct limit lines for spectral measurements such as spectrum emission
or power-versus-time masks.
These ovens are used with the same small food items as domestic ovens, and thus give the same type of spectrum emission
. In addition, stirrers are more common in these ovens, which results in increased frequency fluctuations.
Several built-in functions include channel power, adjacent channel power, occupied bandwidth, spectrum emission
mask, third-order-intercept (TOI) measurement, harmonic distortion, X dB down, and phase noise measurement.
This capability and the advancements made in instrumentation design allow transmitter (TX) measurements, which include output power, frequency error, occupied bandwidth (OBW), spectrum emission
mask, adjacent channel leakage power, error vector magnitude (EVM), and peak code domain error (PCDE), to be conducted in as little as 200 ms.
"Also avoid using LED lighting with blue-rich white light--that will decrease the brightness of night lighting and avoid the deleterious effects of blue spectrum emissions
A general-purpose simulated analysis icon can be used in place of the third icon but only FFT, waveform amplitude, waveform I/Q, and spectrum emissions
mask graphs are available, and the spectrum emissions
mask isn't plotted unless a real VSA is used.
