ISDB-T Measurement Application
N6155A, ISDB-T/TSB Measurement Application
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 10.0
kHz RBW, at a center frequency of 713.142857 MHz.
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.
