Fig. 4-14 Spurious close to the Carrier Screen (Measurement method: Spectrum, RBW: 1.23 MHz)
Notes:
1. When RBW is 30 kHz, the measurement waveform by spectrum analyzer is
displayed.
When RBW is 1 MHz or 1.23 MHz, the measurement waveform by spec-
trum analyzer and the accumulated data by digital processing are displayed.
2. Offset Freq. vs Power displays the measured results by the selected RBW.
3. Template judgment is performed for the measured results by the selected
RBW.
4. When Data Rate is 1/2, 1/4, or 1/8; Tx Power (Modulation) is displayed.
