5 DESIGN AND OPERATION
ST167 is a superheterodyne receiver with digital control and a color OLED display.
It detects signals with digital data transmission protocols, and the entire frequency band of analog
signals.
The detection of DRT signals is carried out by successive scanning of the chosen standards frequency
ranges. The user choses the detection threshold and the number of desired frequency ranges. Signal
identification is based on the analysis of the frequency ranges and time parameters of the detected signal.
The detection of ART signals is carried out by scanning a predetermined band in the frequency range
from 50 to 6000MHz. Demodulation is possible for the AM and FM signals, and their frequency is indicated in
the screen.
5.1 OPERATION MODES
ST167 has four modes of operation: "AUTO", "MANUAL", "SEARCH", "LOG VIEW" and
“SMS/GPRS”.
Fifth mode are analysis of Wi-FI and Bluetooth networks (only for ST167WB).
5.1.1
The "AUTOMATIC" mode is a sequential analysis of user-selected DRT standards and search within
a given range of analog signals. The signals exceeding a predetermined threshold are shown in the screen,
and the information on the detected signals is recorded in the event log.
5.1.2
The "MANUAL" mode provides the ability to control one user selected DRT standard, locate its source
and search for ART signals in the selected frequency range. This mode provides indication of the timeline, as
well as the view of base stations levels.
5.1.3
The "SEARCH" mode is scanning and locating ART signals. Provided sound control signals from the
AM and FM modulation.
5.1.4
"LOG VIEW" Viewing the event log of the unit operation in the "AUTOMATIC" mode. The time and
type of the event, its duration and the signal level are displayed.
5.1.5
The «SMS/GPRS» mode designed for the detection of SMS/GPRS messages of GSM 900, 1800 and
3G 2100MHz standards.
5.1.6
WIFI networks mode is intended for Wi-FI (802.1а,b,g,n) networks analysis.
5.2 LABELS AND SEALING
The marking is on the nameplate mounted on the back cover of the
main unit. It presents the unit name, serial number, space for marking the
full name of the unit and the manufacturer's logo, applied by the intaglio
method.
5.3
PACKAGING
The unit components are transported and stored in a rectangular box 120X70X70 made of
corrugated cardbo
