expressed with the following formula:
BW
BW
1
2
L 10log
Where, ∆L is the change of the noise amplitude, expressed in dB.

Fig. 3.9 Measuring Small Signals by Reducing Resolution Bandwidth
As the reduction of resolution bandwidth will increase the sweep time, in the S3302 Spectrum Analyzer, resolution
bandwidth 1Hz - 10MHz is realized by step 1-3-10. Proper resolution bandwidth should be selected to realize
delicate compromise between sweep time and resolution bandwidth.
3.3.3 Measuring small signals by using average detection and increasing sweep time
When the noise floor of the spectrum analyzer masks small signals, the noise can be smoothed by using the
average detector and increasing the sweep time so as to improve the visibility of such signals. A slower sweep
speed can result in a better mean square error of noise.

3.4 How to Identify Signal with Closely Spaced Frequency
3.4.1 Description of resolution bandwidth
Signal resolution is determined by the bandwidth of IF filter of the Spectrum Analyzer, i.e. the resolution bandwidth
(RBW) When a signal passing through the IF filter, the Spectrum Analyzer uses the signal to sweep the band pass
shape of the IF filter. When the Spectrum Analyzer receives two signals with the same amplitude and closely spaced
frequency, the top of a band pass filter waveform swept by one signal will cover the other signal, and as a result, the
two signals may look like one signal. If the two signals have different amplitudes but the frequency is still close, then
the small signal may be covered up by the response of large signal.
3.4.2 Measurement for distinguish two signals with same amplitude
In general, in order to distinguish two signals of same amplitude, the resolution bandwidth must be less than or
equal to the frequency spacing of two signals. Taking distinguishing signals of same amplitude with a spacing of
100 kHz as an example, the user should select the resolution bandwidth of the Spectrum Analyzer as less than or
equal to 100 kHz.
a) Reset the spectrum analyzer

www.salukitec.com
Press 【Preset】key to restart the spectrum analyzer.
b) Set the signal generator
Use a T connector to connect the output of two signal generators to the RF input port of the Spectrum Analyzer, as
shown in Fig. 3.11. Set the frequency of one signal generator as 300MHz and the other as 300.1MHz and set the
output amplitude of two signal generators as -20dBm. Adjust the signal output amplitude of two signal generators
and observe the signal displayed on the Spectrum Analyzer so that the amplitude of these two signals displayed on
the Spectrum Analyzer is the same.
c) Set the center frequency, span and resolution bandwidth of the spectrum analyzer
Press 【Freq】and [Center Freq] to set the center frequency of the spectrum analyzer to 300MHz, select 【Span】
to set the span to 2MHz, and press【BW】 and [RBW Auto Man] to set the RBW to 300kHz.
d) Observe the signal in the spectrum analyzer
On the display screen of the Spectrum Analyzer, only one signal peak can be seen and signals with close frequency
spacing cannot be distinguished, as shown in Fig. 3.12.
e) Adjust the resolution bandwidth
Press 【BW】and [RBW Auto Man] to adjust the resolution bandwidth to 100kHz so that the resolution bandwidth
is less than or equal to the frequency interval of such two signals. It can now be seen that the signal peak on the
screen becomes flat, which indicates that there may be two signals.
f) Reduce the video bandwidth
Press 【BW】 and [VBW Auto Man] to adjust the video bandwidth to 10kHz. wo signals can be seen on the screen,
as shown in Fig. 3.13. Use the knob or 【 ↓ 】 key on the front panel to continue to reduce the resolution
bandwidth to show two signals more clearly.
For spectrum analyzer which the resolution bandwidth steps in the form of 1-3-10, to distinguish two signals with
the frequency spacing of 200 kHz, the resolution bandwidth must be 100 kHz. As the primary filter on the spectrum
analyzer is 300 kHz which is higher than the 200 kHz frequency spacing, the two signals cannot be distinguished.
