Chapter V Interference Analyzer Measurement Mode (optional)
Section 1 Introduction to Typical Measurements
The interference analyzer mode is an extension of the spectrum analyzer mode. In S3302 series spectrum analyzer,
the interference analyzer mode is divided into the following three modes:
Spectrum measurement (refer to the relevant chapter of spectrum analysis requirements for specific operations, not
repeated here);
Spectrogram measurement;
Received signal strength indicator (RSSI) measurement.
All operations in this chapter are based on the interference analyzer mode, which will not be described separately below.
1 Spectrogram measurement
The cyclic or intermittent signal can be easily observed in the 3D spectrogram display, i.e. frequency, amplitude and
time. The time signal amplitudes are reflected by various colors in the spectrogram display.
In order to better observe the measured signal, the following steps can be taken:
a) Press [Frequency]→[Span]→[Full Span] and [Peak] to obtain the maximum value of the current signal. Then
press [Marker→Center] and set the current peak as the center frequency. In this case, the maximum value will be
displayed at the center of the trace zone.
b) Press [BW]→[RBW Auto Man] and set the appropriate resolution bandwidth with the number keys, [↑], [↓] or
knob. Similarly, set the appropriate video bandwidth.
c) Press [Amplitude]→[Ref Level] and set the current maximum point close to the top of the display zone. Press
[Scale/Div] and set the appropriate scale/division to facilitate viewing
d) Press [Auto Save]→ [Sweep Interval] and set the sweep interval.
