Arinst SSA-TG R2 Portable Spectrum Analyzer with a tracking generator

Arinst SSA-TG R2 is a 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 can operate with signals for all widely used technologies: Wi-Fi, 2G, 3G, 4G, LTE, CDMA, DCS, GSM, GPRS, GLONASS and others.

Another important feature is the presence of additional capabilities of the tracking generator, which makes it possible to measure the frequency response of passive or active devices, for example filters or amplifiers. The software allows measuring SWR and return loss module. This requires an external directional coupler and a set of calibration measures.

Application


Arinst SSA-TG 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
  • repair and adjustment of the repeater, generator, filter, etc.
  • measure SWR when using an external directional coupler.
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 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 smartphone/tablet/PC.

You can install the analyzer software to control by smartphone or tablet from the Google Play or download from here.

You can download the analyzer software to control by PC or laptop from here. 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.

Management analyzer with external programs

There is a possibility of device control using external programs.

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-TG 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.

Users can customize automatic measurements and use the spectrum analyzer Arinst SSA-TG R2 in their system.

An example can be downloaded from here.
