To prevent failure of the input circuit of the spectrum analyzer prohibited from performing signal
level measured near the signal sources than 1 watt (base stations powerful repeaters, Wi-Fi
access point).
The minimum permissible distance from the transceiving antenna to the signal source device to
be at least 30 meters.
If required the analyzer using near powerful sources of signals necessary to use external
attenuators 10 to 30 dB.
1. PURPOSE
1.1. Portable spectrum analyzer ARINST SSA TG R2s (further the analyzer, the device) is designed to
display the spectrums of signals in the frequency range 35-6200 MHz.
The device displays the spectrums of signals of all modern technologies: Wi-Fi, 2G, 3G, 4G, LTE,
CDMA, DCS, GSM, GPRS, GLONASS, etc.
The signal is displayed on the device’s screen in the form of a spectrum graph, a spectrogram, a
trace, and a diagram with «digital phosphor»technology.
This device is intended for home use, as it uses a mathematical method of suppressing the mirror
channel.
1.2. The device is designed to determine the amplitude and frequency of the spectral components
included in the signal.
1.3. The presence of a built-in signal generator, allows you to measure the magnitude-frequency
characteristics of active / passive devices (amplifiers, repeaters, filters) and measure
reflections / standing wave ratio (SWR).
1.4. The device is designed to operate in an ambient temperature range from 0 to plus 50 °С and
relative air humidity of not more than 80% at a temperature of plus 25 °С.
1.5. The analyzer is not intended:
for work on the open areas during a snowfall or a rain;
in places with a corrosive or explosive environment (dust, steam, gas);
for use by people (including children) who have physical, nervous or psychological
abnormalities or lack of experience and knowledge that prevent the safe operation of the device
without supervision or training;
use by children for games.

6. TURNING ON
Attention! Use of the device in open spaces during snowfall or rain is prohibited. If the
appliance was brought in during the winter from a cold room, or from the street into a warm room,
do not turn it on for a time sufficient to evaporate condensate from the device.
Attention! Relate the voltage and power of the input signal to the maximum technical
characteristics of the device indicated in Table 1.
6.1. Turning on the device
6.1.1. Make sure that the device has no external damage and the battery is charged. Charge the
discharged battery before using the device.
6.1.2. To turn on the device, press and hold the button (7) «MENU» for 2-3 seconds. The mode
indicator (11) MODE lights up. The screen (3) will display the results of the device self-test. Then, the
device will switch to normal operation.

7. DEVICE SCREEN
Рисунок 7.1 –Экран прибора
7.1. The screen of the device is a large-scale grid consist of horizontal and vertical lines. On the
horizontal axis, linearly increasing from left to right, the signal frequency is displayed. On the vertical axis,
in the form of a logarithmic scale calibrated in decibels per milliwatt (dBm), the signal amplitude is
displayed.
7.2. At the bottom of the screen is the service information reflecting the current device settings and
parameters of the analyzed signal.
For example, in figure 7.1, the initial frequency of the test signal «Start» is 1945 MHz, the final
frequency «Stop» is 1985 MHz The screen also displays the scan time of the specified frequency range in
milliseconds "ms", in our example equal to 49 milliseconds.
The battery symbol is displayed in the lower left corner, indicating the state of charge. In operation of
the device from an external power source battery charging occurs. In this case, in the lower left corner of
the screen shows the "lightning".
7.3. To moving the screen scale grid left-right (in frequency), briefly press the «FREQ» button (5). In
the lower right corner of the screen, «FREQ» will appear. Use the navigation buttons (9) to move the
screen grid left-right.
Note - when moving the scale grid left-right (in frequency), the specified frequency range is not
changed. The values of the initial «Start», the final «Stop» frequency of the measured signal are
changed.
7.4. To move the screen scale up and down (in amplitude), briefly press the AMPL button (8).
«AMPL» appears in the lower right corner of the screen. Use the navigation buttons (9) to move the
screen grid up and down.
7.5. To move the markers (left-right) in frequency, briefly press the MKR button (6). The inscription
«MK 1» will appear in the lower right corner of the screen (number is the marker serial number). Use the
navigation buttons (9) to change the position of the marker. If there are more than one markers installed,
briefly press the MKR button to switch between them. The designation of the active marker (MK 1 ...
MK 4) will appear in the lower right corner of the screen. On the screen, above the scale grid, information
about the frequency at which the marker and signal strengths are installed will be displayed. The color of
the information line corresponds to the color of the marker on the chart.

Note - Frequency movement is possible only for markers operating in the frequency display mode on
the «Point» graph. More detailed information on the use of markers in measurements is given in
subsection 8.6.
7.6. Changing the frequency range of the overview is done with the buttons (4) «- SPAN +» in all
operating modes of the device (FREQ, AMPL иMK 1-4).
7.7. A spectrogram of the signal can be displayed between the scale grid and the line with service
information when the corresponding option is enabled. See subsection 8.5.3 for a more detailed
description of enabling this option.
