W-CDMA Measurement Application
Amplitude
c. The sensitivity is specified with 0 dB input attenuation. It represents the noise limitations of the ana-
lyzer. It is tested without an input signal. The sensitivity at this offset is specified in the default
30 kHz RBW, at a center frequency of 2 GHz.
d. The relative accuracy is a measure of the ratio of the power at the offset to the main channel power. It
applies for spectrum emission levels in the offsets that are well above the dynamic range limitation.
e. The absolute accuracy of SEM measurement is the same as the absolute accuracy of the spectrum ana-
lyzer. See “Absolute Amplitude Accuracy” on page 34 for more information. The numbers shown are
for 0 - 3.6 GHz, with attenuation set to 10 dB.
