Radio Spectrum Monitoring and Management Laboratory (TCI and STARC4SYS)
www.tcibr.com
www.starc4sys.com
Features:
- TCI Spectrum Monitoring System – Model 753
- TCI Antenna – Model 640 (20 MHz – 8.5 GHz)
- TCI Wideband Active Receive Antenna – Model 7053 (9 kHz – 30 MHz)
- TCI Scorpio Software
Representative laboratory assignments:
- RF Spectrum Mapping from 20 MHz to 8.5 GHz
Use the TCI 753, the Model 640 antenna, and the Scorpio software to identify active radio services, generate a spectrum-occupancy map, and interpret the results. - ISM Band Monitoring and Interference Analysis
Investigate the 433 MHz, 868 MHz, 2.4 GHz, or 5 GHz bands; detect emissions, measure signal levels, and distinguish intended signals from sources of interference. - Characterization of FM Broadcast Signals
Measure the received frequency, bandwidth, signal level, and spectrum occupancy for FM broadcast stations, then compare the measurements collected at different locations. - HF Spectrum Analysis: 9 kHz–30 MHz
Using the TCI 7053 active receive antenna, identify HF transmissions such as broadcast and amateur radio, and study how reception varies throughout the day. - Detection and Approximate Location of an Unauthorized RF Transmitter
Set up a controlled laboratory transmitter and estimate its direction or approximate location using successive measurements with the TCI 753 and Scorpio software. - Time-Based Spectrum Occupancy Study
Set up a 24-hour or one-week monitoring campaign and calculate channel occupancy, transmission duration, and temporal variation for a selected frequency band. - Automated RF Signal Identification and Classification
Extract relevant parameters from Scorpio—frequency, bandwidth, duration, level, and modulation type—and develop rule-based methods for classifying detected emissions. - Electromagnetic Compatibility Assessment in a Laboratory Environment
Measure background electromagnetic noise and emissions generated by common equipment, such as switching power supplies, displays, routers, cables, or IoT devices. Identify and report problematic areas. - Performance Comparison of the TCI 640 and TCI 7053 Antennas
Compare the antennas within their overlapping frequency range, focusing on sensitivity, received noise, types of signals that can be detected, and installation constraints. - RF Monitoring Plan for a High-Density Event
Develop a monitoring plan for a hypothetical large-scale event: select priority frequency bands, configure alarm thresholds in Scorpio, collect data, and produce a technical spectrum incident report.
