Real-Time RF Analysis & Interference Detection for Field and Defense Applications.
In modern defense and field communication environments, RF interference is often unpredictable, fast-changing, and difficult to trace. The TFN RMT Series is designed to give engineers and field units immediate visibility into the electromagnetic environment—what is transmitting, where it comes from, and how it affects mission-critical communications.
Features:
- Frequency range from 5 kHz to 40 GHz
- Real-time spectrum capture up to 100 MHz bandwidth
- High-speed scanning for transient and hidden signals
- 5G NR / LTE / GSM / NB-IoT signal analysis and demodulation
- 10.1-inch Full-Screen Field-Optimized Display
- Intuitive UI designed for rapid RF analysis workflows
Description
- Detects what cannot be seen in static scans
Traditional sweep-only instruments often miss short-duration or frequency-hopping signals. The RMT Series uses real-time spectrum processing to continuously capture RF activity, ensuring transient interference, burst emissions, and covert signals are visible during operation. - Turns spectrum data into actionable signal intelligence
Beyond basic signal presence detection, the system decodes cellular and IoT signals including 5G NR and LTE. Engineers can directly evaluate signal quality metrics such as EVM, channel power, ACLR, PCI, and beam-related parameters to determine whether issues originate from interference, network configuration, or hardware degradation. - Locates interference sources in real environments
With integrated AOA direction finding and GPS mapping, the system converts RF signals into spatial direction data. Field operators can track emitters step-by-step in urban, border, or mountainous environments, significantly reducing search time. - Provides multi-dimensional RF visualization
Waterfall spectrum, persistence display, and time-gated analysis allow users to understand how signals evolve over time—critical for identifying intermittent interference or hidden periodic transmissions. - Built for field deployment, not lab conditions
Lightweight handheld structure, sunlight-readable display, and long battery life ensure continuous operation in remote or harsh environments.
5G NR Signal Analysis
Provides in-depth analysis of 5G NR signals including key physical layer parameters and link performance indicators.
Supports rapid verification of network quality in field deployments and private network environments.
Channel Power Measurement
Measures integrated signal power within user-defined frequency bands, enabling accurate assessment of signal strength and spectral occupancy.
Supports fast validation of transmitter output and channel utilization.
Persistence Spectrum Display
Visualizes RF activity over time by accumulating spectral traces, enabling detection of intermittent, burst, and low-duty-cycle signals that are otherwise difficult to observe in real-time sweep mode.
Waterfall Spectrum Display
Provides a continuous time-frequency representation of RF activity, enabling users to observe signal evolution, frequency occupancy, and temporal patterns in dynamic spectrum environments.

Military & Defense Fiber Network Applications
Border & Contested Spectrum Surveillance
Border regions often contain overlapping civilian, military, and cross-border RF activity. Unknown emitters or unauthorized transmissions can disrupt secure communications.
The RMT Series enables continuous spectrum scanning and direction-based tracking, allowing operators to quickly isolate and physically locate interference sources even when signals are intermittent or mobile.
Tactical Communication Network Assurance
In deployed environments, communication quality can degrade due to terrain obstruction, antenna misalignment, or hostile jamming.
The RMT Series helps field teams verify signal integrity in real time, checking modulation quality and channel conditions of LTE/5G-based tactical networks to ensure stable command-and-control communication.
Radar & Electronic Environment Monitoring
Modern operational zones contain overlapping radar pulses, navigation systems, and communication links. This creates a dense RF environment where signal conflicts are difficult to diagnose.
The RMT Series captures wideband RF activity and visualizes pulse behavior, helping analysts distinguish between expected system emissions and anomalous or unknown signals.
Frequently Asked Questions
Can the RMT Series be used in military environments?
