3.3 3.3 Spectrum Spectrum
3.3 3.3 Spectrum Spectrum
S7000's spectrum function can monitor the signal of CAB&TERR. Refer to Figure 3-21.
The display spectrum dynamic range is up to 80dB:
�
Adjust REF level manually and automatically.
� Adjust SCALE manually and automatically.
�
Double Mark, the bottom of screen displays the marker frequency and level.
� Pre-Amplifier adjustment.
�
The PEAK function can keep the maximum of all frequency.
� Noise threshold, the system ignores the signal below the threshold.
