Spectrum emission mask (SEM)
The new N9340B adds Spectrum Emission Mask (SEM) as a standard feature.
SEMis a mask for out-of-channel emissions measurement. The SEMis defined
relative to in-channel power.
The user can set the parameters of the main channel, out-of-channel frequency
bands, and the limit lines. Included is Pass/Fail testing for the overall spectrum
emission mask and each individual out-of-channel frequency range. The N9340B
will trigger the failure indicator once any measurement result violates the mask.
Also displayed are the main channel power and the power level metrics relative
to in-channel power for each out-of-channel frequency range. The user can
save the spectrum scan, the mask, the data or screenshot for later analysis and
reporting.
The spectrum emission mask shows the
main channel power and the power level
vectors relative to in-channel power for
each out-of-channel frequency range.
