resolution bandwidth of the analyzer will be adjusted to smaller values
automatically.
Select Multichan Pwr and then press Meas Setup to set the corresponding
parameters.
5. Occupied BW
Integrates the power within the whole span and then calculates the bandwidth
occupied by this power according to the specified power ratio. The OBW
function also indicates the difference (namely "Transmit Freq Error") between
the center frequency of the channel and the center frequency of the analyzer.
Select Occupied BW and then press Meas Setup to set the corresponding
parameters.
6. Emission BW
Measures the bandwidth between two points on the signal which are X dB below
the highest point within the span.
Selects Emission BW and then press Meas Setup to set the corresponding
parameters.
7. C/N Ratio
Measures the power of the carrier and that of the noise with the specified
bandwidth, as well as their power ratio.
Select C/N Ratio and then press Meas Setup to set the corresponding
parameters.
8. Harmo Dist
Measures the power of each order of harmonic and THD (total harmonic
distortion) of the carrier. The highest order of harmonics for measurement is 10.
The fundamental harmonic amplitude of the carrier signal must be greater than
-50 dBm; otherwise the measurement will be invalid.
Select Harmo Dist and then press Meas Setup to set the corresponding
parameters.
9. TOI
Measures the third-order intercept (TOI) of a two-tone signal (with the same
amplitude and similar frequency), including the frequencies and amplitudes of
Lower Tone, Upper Tone, Lower 3rd TOI, and Upper 3rd TOI, as well as the
intercept points of both the Lower 3rd TOI and Upper 3rd TOI.
Select TOI and then press Meas Setup to set the corresponding parameters.
