Arinst SSA R2 is an easy
portable panoramic spectrum analyzer designed to
display signal spectrums in the frequency range from 35 to 6200
MHz. The analyzer finds the amplitude and frequency of spectral
components of the analyzed process.
Spectrum analyzer is able to find the signal amplitude for all
widely used technologies: Wi-Fi, 2G, 3G, 4G, LTE, CDMA, DCS,
GSM, GPRS, GLONASS and others.

This manual is written for the senior model, but in the main
parts is suitable for this device.
Application
Arinst SSA R2 is primarily intended for field operation. The
device is rugged and light with low energy consumption. It
enables service centers and maintenance teams to perform
on-the-spot HF analysis for commissioning and repair works.
Moreover, the spectrum analyzer is a perfect solution for
repair workshops and radio amateurs.
For example, using the
device you can perform the following operations:
- put an external antenna on the base station
- to conduct a rapid analysis of RF environments
- check the correct operation of the repeater cellular
Principle of operation
The spectrum analyzer is a portable device that is connected to
the measured circuit and has an independent power supply. The
device has a 3.2" color resistive touch screen to display the
signal spectrum and to control the device.
The device is controlled by one of three ways:
- by buttons and touchscreen on the device.
- by an Android powered smartphone or tablet.
- by a PC or laptop with Windows operating system
The data between the analyzer and smartphone/tablet/PC is
transmitted through Bluetooth or USB-cable. The Bluetooth range
is up to 10 m (Password for connecting via Bluetooth: 1234).
All the measured data is displayed in real time on the screen
of the device or smartphone/tablet/PC.
You can install the analyzer software to control by smartphone
or tablet from the Google Play (play.google.com/store/apps/details?id=com.arinst.ssa)
or download from www.arinst.net/download-apk.php
You can download the analyzer software to
control by PC or laptop from www.arinst.net/download-apk.php. Windows
7 or higher and the latest version of Java Virtual Machine are
required for the correct work of
application. The
application requires full (100%) support for OpenGL version 2.1
and higher.
API
There is a possibility of device control using API.
You can send the device a command to make a measurement
(scanning range) with the following parameters:
- start frequency
- stop frequency
- measuring step
- the value of the attenuator
After the command completes, the device Arinst SSA R2 will send
the client device (microcontroller, computer, mobile
device, etc.) a message containing the measured values of the
amplitudes for the given frequency values. The user can record
the received data to a file, database, etc.
Using this API users can customize automatic measurements and
use the spectrum analyzer Arinst SSA R2 in their system. The
API works in any programming language that supports work with
input-output ports (Java, C, C++, C#, Python, Assembler, etc.).
An example of using the API can be downloaded
from www.arinst.net/download-apk.php.
Basic functions of the analyzer software:
- Displays the signal spectrums graphically and sets up the
frequency range and reference limit.
- Sets up and manages absolute and relative (delta) markers.
- Searches one or a series (up to ten) of maximum values of
the signal in the instantaneous or tracking mode.
- Sets and stores unique identifiers of the frequency ranges
- bands. For instance, a band titled «DCS
UpLink» can be set for the range 1710-1785 MHz.
Additionally, working frequency bands can be set for each
operator. This option considerably facilitates the HF analysis
and identification for the signals of conventional
technologies.
- Has pre-set bands and is able to store
the bands in a
file and share them with other devices to control the spectrum
analyzers Arinst SSA.
- Has the tracing mode that generates a signal spectrum
averaged by a number of measurements. In addition to the
average spectrum, extreme values and moving average values can
be displayed as well.
- Stores the settings for the spectrum scanning (band limits,
attenuator value and others) for a quick and easy switching
into the required measurement mode.
- Stores the spectrum signal with markers for later analysis.
Then the stored graph can be opened in any Android device with
the application «Arinst SSA» (in this event you don’t need to
have the spectrum analyzer at hand) or use the table editor to
convert the graph into the required type of data display.

Items included in the box:
- Spectrum analyzer Arinst SSA R2
- Battery (pre-set inside the device)
- HF adapter SMA(male)-SMA(female) to protect the HF
connector from wear-and-tear
- USB – mini-USB cable to charge the device and for data
transmission
Items not included in the box:
- Smartphone or tablet under the Android’s 4.0.3 control or
higher. Use your Android powered device in order to control the
equipment. The device is implemented in one body, while the
equipment for its control is built in another. It has been done
in order to make the spectrum analyzer much simpler and more
available. Also, use your laptop or computer for controlling
the device.
- External attenuation network. The maximum measured input
power, which is supplied to the device, is limited by +5 dBm.
If it is necessary to measure a larger value, each user of the
device has to select the necessary attenuators on one’s
own.
- Set of the super-high frequency adapters.
Limitations
The spectrum analyzer Arinst SSA R2 is not a measure gauge, as
it does not have an approved pattern of the measuring
equipment. The approval of pattern of the measuring equipment
has had a negative effect on the availability and price of the
device. For this reason the spectrum analyzer is officially
considered a field indicator. However, the device fully meets
all technical requirements. Each device is calibrated against
the power and frequency.
