This equipment differs from the PRO version without additional adaptors and the external attenuator at 30 dB.

Portable spectrum analyzer Arinst SSA Lite R2 is designed to display spectra signals in the frequency range from 35 to 6200 MHz. The device allows to determine the amplitude and frequency of spectral components included in the signal.

The spectrum analyzer displays the spectra of signals of all common technologies: wifi, 2G, 3G, 4G, LTE, CDMA, DCS, GSM, GPRS, GLONASS, etc.

Purpose

Spectrum analyzer ARINST SSA Lite R2 is designed primarily for practical work, it has a very small weight and dimensions and has a low power consumption. With it, service centers and repair crews can conduct an RF analysis to commissioning or repair work. In addition, the spectrum analyzer is ideal for repair shops and hobbyists.

How does it work?

Spectrum analyzer made in the form of a mobile device with Autonomous power supply, which is connected in the measuring circuit. The device has a 3.2" color resistive touch screen to display the signal spectrum and to control the device. In addition, the device is controlled by a smartphone or tablet running Android version 4.1-8.1.

Data between the device and the smartphone are transmitted both through the built-in Bluetooth module, and USB cable. Bluetooth operating range up to 10 meters (the Password to access via Bluetooth: 1234).

All measured data in real time are displayed on the device screen or smartphone/tablet.

To control the spectrum analyzer with the smartphone/tablet from Google Play need to install software or download latest version from site and install it manually.

For normal operation of the application requires Windows 7 or higher and the latest version of the Java Virtual Machine.

The application requires full (100%) OpenGL version support 2.1 and above.

API

There is a possibility of device control using API.

You can send the device a command to perform a measurement (scanning range) with the following parameters:

  • initial frequency
  • the final frequency
  • step measurements
  • the value of the attenuator

After the command completes, the device Arinst SSA R2 will be sent to the client (microcontroller, computer, mobile device, etc.) a message containing the measured values of the amplitudes at specified frequencies. The user can record the received data to a file, database, etc.

Using this API the user can customize automatic measurements and use the spectrum analyzer Arinst SSA R2 in their system. The API works in any programming language supporting port I / o (Java, C, C++, C#, Python, Assembler, etc.).

Example of API use you can download here.

Wiring diagram of the analyzer.

Main functions of the application to control the device:

    • View spectrum signals in the form of graphs, with the installation of the frequency range and reference level

    • Installation and management of absolute and relative (Delta) markers

    • A search of one or several (up to ten) the maximum values of the signal in the snapshot or tracking modes

    • The purpose and preservation of the unique identifiers for the ranges of frequencies – the "regions". For example, you can assign a "region" called "DCS UpLink" band 1710-1785 MHz. And also you can assign working frequencies for each operator. This option greatly facilitates the RF-analysis and identification of signals with standard technologies.

    • The presence of predefined "regions", as well as the ability to save the "regions" file and share them with other devices to control the spectrum analyzer Arinst SSA R2.

    • The trace mode, which is based is averaged over multiple measurements of the spectrum of the signal. In addition to the average possible display modes are the extreme values, moving average. The number of measurements for the trace selected by the user.

    • Save settings scan the spectrum (the boundaries of the frequency range, the value of the attenuator, etc.) for quick and easy switch to the desired mode of measurement.

    • The preservation of the signal spectrum together with the markers for further analysis. With this saved chart can be opened on any Android device with installed application "Arinst SSA R2" (it is not necessary to have the spectrum analyzer), or convert into the desired form using any table editor.

Limitations

Spectrum analyzer Arinst SSA R2 is not a measuring device, since it has type-approved measuring instruments. Type approval of a measuring instrument would result in affecting the availability and price of the device. Therefore, the spectrum analyzer from the official point of view is the field indicator. However, despite this, the device meets all stated specifications. Each instrument is calibrated in power and frequency.

Analyzer is a complete classical spectrum analyzer, because it does not use the classical scheme of frequency conversion to 100% suppression of the mirror channel. We use a mathematical image rejection that in some rare cases may lead to the appearance of the displayed signals the "phantom" signals.

Additional Information

  • Essentially, the device is "RF multimeter" or "RF explorer";
  • The device has a manufacturer's warranty for 1 year from the date of purchase;
  • The device does not work with iPhones and other Apple products;
