7 RF spectrum menu
· [Special note]: The occupied bandwidth measurement in the
RF spectrum is similar to that in the spectrum analyzer mode.
The RF spectrum is only applied in the AM-FM-PM analyzer
mode.
· [OBW Off On]:
Press [RF Spectrum]→ [OBW Off On] to
enable or disable the occupied bandwidth measurement.
· [Method % dBc]:
Press [RF Spectrum]→ [Method % dBc] and
select various measurement methods: percentage or drop dBc. In
the percentage method, the occupied bandwidth of the signal is
obtained by calculating the bandwidth of the frequency of certain
percentage to the total power of the transmitted power, and the
power percentage can be set by the user. In the drop dBc method,
the occupied bandwidth is defined as follows: spacing between two
frequency points corresponding to signal power drop by dBc on
both sides of the frequency point where the signal peak power is.
The signal power drop dBc can be set by the user.
· [Percentage]:
Press [RF Spectrum]→ [%] and set the
percentage.
·[XdB]:
Press [RF Spectrum]→ [dBc] and set the dBc value.
