1.1 Overview of Spectrum Analyzer
The MS2690A/MS2691A/MS2692A Signal Analyzer (hereinafter, referred
to as “MS2690A/MS2691A/MS2692A”) is a device used for the quick,
highly accurate, and simple measurement of the transmission
characteristics of various wireless devices and systems.
The spectrum analyzer function enables full-span analysis of a broad
spectrum, which is a characteristic of conventional sweep type spectrum
analyzers, and realizes quick and highly accurate signal processing
through the use of a digital IF block. These features make the Spectrum
Analyzer function ideal for various applications ranging from R&D to
manufacturing.
The Spectrum Analyzer function has the following features.
Frequency band (6 GHz/13.5 GHz/26.5 GHz)
•
Broad analysis bandwidth (20 MHz)
•
High dynamic range (180 dB)
•
High-speed and high-accuracy signal analysis through digital IF

A spectrum analyzer is a measuring device for analyzing the frequency
components of an input signal. The relative values of the various
frequency components are displayed in graph form, with the horizontal
axis representing the frequency and the vertical axis the signal level.
Figure 1.2-1 shows a schematic representation of a signal that includes a
harmonic distortion component as observed with an oscilloscope and a
spectrum analyzer. Observation of a signal that includes harmonic
components with an oscilloscope yields a waveform with distortion, not a
sine wave. This indicates that the signal includes harmonic components,
but the magnitudes of the various harmonic components cannot be
quantitatively measured. Using a spectrum analyzer enables the
quantitative grasp of signal components by dividing the signal
components into their various frequency components and graphing each
frequency and amplitude. In the example shown in Figure 1.2-1, the
signal can be seen to consist of a fundamental wave (f0) and a second
harmonic component (2

f0), and their respective amplitudes can be read

Spectrum analyzer principle
A spectrum analyzer separates the input signal down to the level of
single frequencies and obtains their respective amplitudes. Concretely,
following extraction of single frequencies using a narrow-band filter(s),
their amplitudes are obtained through wave detection. Separation into
the various signal components through the use of a filter(s) can be done
using two different methods. One method consists in using multiple
filters to obtain the various frequency components in one time (real-time
method), while the other method consists in obtaining the various
frequency components by changing the center frequency of a single filter
over time (sweep method).

Chapter 1 Overview
The real-time method, which is characterized by a small time lag, is
suitable for measurement in a narrow frequency range of several tens of
MHz maximum. Compared to the real-time method, the sweep method
requires a long time to draw a screen, but since it allows observation of a
wide frequency range on the order of several GHz at one time, it is a
powerful method for high-order harmonic level measurement and the
detection of unknown frequency components.

1.2 Features of Spectrum Analyzer
Overview
Figure 1.2-3 shows the configuration of a typical sweep-type spectrum
analyzer. The super heterodyne method, which is one of the methods that
can be used for implementing a sweep-type spectrum analyzer, is
described below. The input signal from external sources passes through
an input circuit consisting of an attenuator and a preselector and is
mixed with the signal from the local oscillator by a mixer. Here, the input
signal is converted into a signal of a given frequency (IF). After being
processed through an IF stage, this IF signal determines the vertical axis
(level) on the display based on its level. The local oscillator, which
operates on the principle that the oscillation voltage changes according to
the input voltage, is controlled by the signal from the sweep signal
generator (sawtooth wave generator) and determines the horizontal axis
(frequency) of the display. As a result, a level that corresponds to the
input frequency is displayed as a graph.
The input circuit consists of an attenuator for input signal level
adjustment, and a pre-selector that prevents erroneous measurement by
reducing responses other than that of the reception signal. The IF stage
consists of an IF filter used to separate only the target frequency, an IF
amplifier with a gain stabilized across a wide level range, and a
logarithmic amplifier with excellent linearity. The MS2690A/MS2691A/
MS2692A employs a digital IF method in its IF stage to obtain superior
linearity and selectivity.

2.5.1 Setting resolution bandwidth (RBW)
Auto or Manual can be selected for setting resolution bandwidth (RBW).
Auto
The resolution bandwidth is automatically set according to the
frequency span setting.
Manual
Select an arbitrary resolution bandwidth (RBW). When monitoring
two adjacent signals, the frequency resolution can be increased by
reducing the resolution bandwidth (RBW). This has also the effect of
reducing the noise level.
The resolution bandwidth (RBW) value can be selected from among the
following:
30 Hz, 100 Hz, 300 Hz, 1 kHz, 3 kHz, 10 kHz, 30 kHz, 50 kHz, 100 kHz,
300 kHz, 1 MHz, 3 MHz, 5 MHz, 10 MHz, 20 MHz, 31.25 MHz
(31.25 MHz is available only with 0 span.)
Note:
For RBW 31.25 MHz, it is not a Gauss filter but a flat-top
characteristic filter. If Couple Time/Frequency Domain is set to Off,
this parameter specifies a separate value for frequency-axis
measurement and time-axis measurement.
When Couple Time/Frequency Domain is set to Off, each parameter is
specified in accordance with the already-specified frequency axis or time
axis measurement.

2.5 Setting RBW/VBW
Auto
The video bandwidth is set to the same as the resolution bandwidth
(RBW) or the nearest value.
Manual
By setting the video bandwidth to a value that is smaller than the
resolution bandwidth (RBW), noise averaging is made more efficient.
The video bandwidth (VBW) value can be selected from the following:
1 Hz, 3 Hz, 10 Hz, 30 Hz, 100 Hz, 300 Hz, 1 kHz, 3 kHz, 5 kHz,

When the detection mode (Detection) is “RMS,” “Power VBW” is
performed regardless of VBW Mode (Video/Power).
Differences between Two VBW Modes
Video VBW
Performs smoothing and averaging with a video filter after
logarithmic compression (logarithmic mean).
Power VBW
Performs smoothing and averaging with a video filter before
logarithmic compression (antilog mean).
Video VBW indicates similar measurement values as those obtained with
a conventional spectrum analyzer, but in the case of signals that
fluctuate importantly over time, such as burst waves, a large error
margin results. When measuring such signals, select Power for the VBW
mode.

3.4.2 Waveform files for Save on Event
This section describes Waveform files to be saved when the Save on
Event function is turned on.
Save destination and load source for Waveform files
After the parameters are set, a folder is created by the name including a
timestamp of measurement start. Then, a csv file containing multiple
data sets is created and stored in the folder.
Save destination for Waveform files
Example: When starting measurement on April 16 at 15:29, a file save
destination is as follows:
< D:¥Anritsu Corporation¥Signal Analyzer¥User Data¥Waveform¥04161529_1>
The number of the end of "04161529_1" is incremented automatically in
order of "04161529_1", "04161529_2", and "04161529_3." It will be set to
