The IQ capture function is applied to capture IQ data and save such data into the instrument based on the capture
time, sample rate and capture mode set by the user.
 Audio monitor
The spectrum analyzer has the tune listening function, which can be applied for radio monitoring. The sound effect
can be improved by adjusting the resolution bandwidth during demodulation of the sound difference. In the
demodulation mode, the resolution bandwidth should be preferably set as 300kHz-30kHz.
Section 1 Introduction to Typical Measurements
The spectrum analysis mode of S3302 series is a basic operating mode. The Quick Operation Guide of S3302
Series Spectrum Analyzer has introduces some typical measurement of this mode, including some basic
measurement methods such as basic signal measurement, improvement of frequency measurement accuracy,
measurement of small signals and distinguishing of signals of approximate frequencies. Additionally, this section
introduces the advanced typical measurement functions and methods of the spectrum analysis mode of S3302
series, mainly including:
a) Channel power measurement;
b) Occupied bandwidth measurement;
c) Adjacent channel power ratio measurement;
d) Third-order IM distortion measurement;
e) Drift signal measurement;
f) Noise signal measurement;
g) Distortion measurement;
h) Pulse RF signal measurement.
i) Signal source measurement (option).
j) Coverage map (option).
