Resolving Signals of Equal Amplitude
In this example a decrease in resolution bandwidth
is used in combination with a decrease in video
bandwidth to resolve two signals of equal
amplitude with a frequency separation of 100 kHz.
Notice that the final RBW selected is the same
width as the signal separation, while the VBW is
slightly narrower than the RBW.
1 Connect two sources to the analyzer input as
shown below.

Setup for obtaining two signals
2 Set on
e source to 300 MHz. Set the frequency of
the other source to 300.1 MHz. Set both source
amplitudes to –20 dBm.
3 Setup the analyzer to view the signals:
• Press [PRESET]
• Press [FREQ] > 300.05 > {MHz}
• Press [SPAN] > 2 > {MHz}
• Press [BW] > 30 > {kHz}
Use the knob or the arrow keys to further reduce
the resolution bandwidth and better resolve the
signals.
