Arinst SSA R2 Signal Hunter is an easy portable spectrum analyzer designed to display signal spectrums in the frequency range from 35 to 6200 MHz. The device allows to determine the amplitude and frequency of the spectral components that compose the signal.

Spectrum analyzer can operate with signals for all widely used technologies: Wi-Fi, 2G, 3G, 4G, LTE, CDMA, DCS, GSM, GPRS, GLONASS etc.

The main purpose of the device is the detection of packet (pulsed) radio signals and radio transmitting devices of all modern communication systems. High scanning speed compared to other versions of ARINST analyzers is achieved through the use of two frequency synthesizers. For advanced analysis, functions for displaying the time-frequency spectrum “waterfall chart” and “digital phosphorus” have been added. They are designed to observe the evolution of signals in both the frequency and time domains.

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.

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.

All measured data are displayed on the device screen in the real time.

​The main functions of the application for controlling the device:

Viewing the spectrum of signals in the form of graphs with setting the frequency range and reference level. In the additional “trace” mode the minimum signal values (green spectrogram), maximum values (red spectrogram) or average values (yellow spectrogram) are displayed. An additional display mode of the frequency-time diagram of the signal allows to analyze the background of the signal for a certain time interval. Due to the selectivity of the color perception of a person, with the help of the frequency-time diagram it is possible to detect signals at a noise level. An additional “digital phosphorus” display mode is an alternative way to visualize the time-frequency diagram, in which the signal amplitudes are displayed on a scale, and their temporal location is set in a color.

​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


The spectrum analyzer is not a measuring device, since it does not have an approved pattern of the measuring instrument. The approval of the pattern of the measuring instrument would adversely affect the availability and price of the instrument. Therefore, the spectrum analyzer from an official point of view is a field indicator. However, despite this, the device fully complies with all declared technical specifications. Each instrument is calibrated by power and frequency.

The analyzer is not a sterling classical spectrum analyzer, since it does not use the classical frequency conversion circuit for 100% suppression of the mirror channel. We use mathematical suppression of the mirror channel, which in some rare cases can lead to the appearance of “phantom” signals in the displayed signals.
