1.1 Overview of Signal Analyzer
The MS2830A, MS2840A, and MS2850A Signal Analyzer is a spectrum
analyzer to which options such as real-time signal analysis and vector
modulation analysis can be added.
The signal analyzer application (hereinafter “this application”) enables
high-speed and high-accuracy signal processing of wide-ranging analyses
at full-span, a characteristic of conventional sweep-type spectrum
analyzers, using a digital IF block. In addition, the FFT process
(high-speed Fourier conversion) realizes high-speed spectrum analysis
and simultaneous analysis on frequency and time axes not possible with
conventional sweep-type spectrum analyzers. Also, added option enables
recording of the RF input signal as digital data (digitize function). It can
be used in a variety of applications from research and development to
manufacturing thanks to its characteristics.
The Signal Analyzer function has the following features:
•Broad frequency band
MS2830A: 3.6 GHz/6 GHz/13.5 GHz/26.5 GHz/43 GHz
MS2840A: 3.6 GHz/6 GHz/26.5 GHz/44.5 GHz
MS2850A: 32 GHz/44.5 GHz
•Broad analysis bandwidth

Overview
1.2 Features of Signal Analyzer
A signal analyzer can perform analysis with both the frequency and time
axes. It achieves high-speed spectrum analysis by using fast Fourier
transformation (FFT) technology.
Differences from a sweep type spectrum analyzer
This section compares the signal analyzer with a conventional sweep
type spectrum analyzer and describes the differences.
Figure 1.2-1 Principle of a sweep type spectrum analyzer
As shown in Figure 1.2-1, a sweep type spectrum analyzer sweeps a filter
with a certain frequency band. Because observation is done only within
the filter band, only one frequency can be observed at one given moment.
To analyze a spectrum of multiple signals simultaneously, the filter must
be swept in the entire band, and no signal can be detected for a high
sweep speed (i.e., short sweep time). This results in a limitation of the
sweep speed for accurate measurement.
On the other hand, the signal analyzer captures the time domain data
and performs FFT processing to display all the signals in the frequency
band simultaneously, quickly, and accurately.

Figure 1.2-2 Principle of Signal Analyzer
Analyzing captured IQ data in various domains
The signal analyzer can analyze simultaneous input signals by capturing
IQ data for a certain time interval.
Spectrum: Performs spectrum analysis by the FFT method. It
performs noise measurement and power
measurement of modulation signal waves accurately
and quickly, which are difficult to measure
accurately by using a sweep type spectrum analyzer.
Power vs Time: Observes time fluctuations of power. It performs
burst average power accurately and quickly.
Frequency vs Time: Observes time fluctuations of frequency. It can
perform frequency lock time measurement without
using any special instrument.
Phase vs Time: Measures time fluctuation of phase.
CCDF: Performs Complementary Cumulative Distribution
Function (CCDF) analysis.
Spectrogram Performs Spectrogram analysis. It is used to
diagram the changes in a spectrum over time.
No Trace: Only captures IQ data without executing signal
analysis.

Figure 1.2-3 Multiple analyses
As shown in Figure 1.2-3, once the IQ data for a certain time interval is
captured, 6 types of analysis methods can be selected for analysis in the
time range. When No Trace is selected, only IQ data is captured without
executing signal analysis.
