Arinst SSA-TG R3 – is a portable panoramic spectrum analyzer with a built-in tracking generator and demodulator, designed to display the spectral components of signals in the frequency range from 24 MHz to 12 GHz. High scanning speed makes it possible to detect impulse signals of digital communication standards: Wi-Fi, 2G, 3G, 4G, LTE, CDMA, DCS, GSM, GPRS, GLONASS, etc. The built-in tracking generator allows you to measure the frequency response of passive or active devices, such as filters, amplifiers. The WFM/FM/AM signal software demodulator is designed for listening to the air and tuning analog radio transmitters. Setting the regional coverage frequencies of cellular operators allows you to match the displayed signal with the corresponding operator.

A full description of all the functions of the analyzer is available at this link

For ease of operation, the built-in software of the device allows you to sign and highlight frequency ranges on the screen with color. For example, sign the names of radio stations, WiFi channels or frequency ranges of mobile operators.

For whom?

The spectrum analyzer ARINST SSA-TG R3 is designed primarily for field work, it has a small weight, size and low power consumption. With its help, service centers and repair teams can conduct RF analysis on the spot for commissioning or repair work. In addition, the spectrum analyzer is ideal for repair shops and radio amateurs.

With the help of the device, the following works can be performed:

  • point the external antenna at the base station
  • conduct an express analysis of the radio frequency environment
  • check the correct operation of the cellular repeater
  • repair and configure the repeater, generator, filter
  • set up a radio transmitter with analog modulation

How does it work?

The device is built on the basis of superheterodyne conversion of the spectrum to a zero intermediate frequency, contains a high-performance microprocessor that performs digital signal processing. With its help, it was possible to achieve a high scanning speed of up to 20 GHz / s and a frequency resolution of up to 2.5 kHz, as well as implement software demodulation of analog signals. To expand the dynamic range of the input signals, the analyzer is equipped with a low-noise amplifier and a fixed attenuator. Built-in tracking generator with adjustable output power allows you to measure cables, filters, etc.

Advantages of the spectrum analyzer ARINST SSA-TG R3:

  • color touch IPS display with a diagonal of 4 inches
  • wide frequency range: 24 MHz to 12 GHz
  • high scanning speed: up to 20 GHz/s

  • full dynamic range including LNA and attenuator 125 dB
  • display of regional frequency distributions
  • customizable display themes
  • charging from mini-USB or from an external power supply with a voltage of 7-24 V
  • light weight and size: weight 400 g, dimensions 145x81x27 mm
  • autonomous operation up to 4 hours

Restrictions

The spectrum analyzer Arinst SSA-TG R3 is not a measuring device, as it does not have an approved type of measuring instrument. Approval of the type of measuring instrument would negatively affect the availability and price of the device. Therefore, the spectrum analyzer from the official point of view is an indicator of the field. However, despite this, the device fully complies with all the declared technical characteristics. The analyzer is not a full-fledged classical spectrum analyzer, because it does not use the classical frequency conversion scheme 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.
