1. 5G Sub-6 GHz Development & Deployment Testing

As 5G technology continues to expand globally, the demand for reliable testing tools for sub-6 GHz 5G networks (a critical band for wide-area coverage and high-speed data transmission) has grown exponentially. The TG44A is uniquely positioned to support 5G sub-6 GHz testing with its compliance to 3GPP specifications and high-fidelity signal generation.

In R&D phases, the TG44A enables engineers to generate standardized 5G NR (New Radio) signals with configurable parameters such as channel bandwidth (up to 400 MHz), modulation types (from QPSK to 256QAM), and frame structures. This allows for rigorous testing of 5G terminal devices (e.g., smartphones, CPEs, and IoT gateways) to verify key performance indicators (KPIs) like receiver sensitivity, error vector magnitude (EVM), and spectral efficiency. For base station component testing, the TG44A provides stable input signals to validate the performance of antenna arrays, transceivers, and power amplifiers, ensuring they meet the strict linearity and efficiency requirements of 5G systems.

During network deployment, the TG44A’s portable, USB-powered design makes it ideal for on-site testing. Technicians can use it to verify 5G base station coverage, test signal propagation in urban canyons or indoor environments, and troubleshoot interference issues. By generating 5G NR signals that simulate real-world traffic, the TG44A helps optimize network deployment and ensure consistent service quality for end-users.

2. Wi-Fi 6/7 & Advanced IoT Sensor Testing

The TG44A caters to the evolving needs of wireless connectivity, supporting testing for Wi-Fi 6/7 (2.4 GHz, 5 GHz, and 6 GHz bands) and advanced IoT sensors operating in the 24–44 GHz emerging frequency range. These applications demand wideband signal generation and precise control to validate high-data-rate transmission and reliable connectivity.

For Wi-Fi 6/7 testing, the TG44A’s 1 GHz real-time bandwidth enables the generation of wideband OFDM signals that comply with IEEE 802.11ax/be standards. It allows engineers to test Wi-Fi devices (e.g., routers, access points, and client devices) for performance metrics such as data transmission rate, latency, and multi-user MIMO (MU-MIMO) capability. Additionally, the TG44A can simulate complex interference environments (e.g., co-channel interference from neighboring Wi-Fi networks or other wireless devices) to evaluate the anti-interference performance of Wi-Fi 6/7 devices, ensuring they deliver stable connectivity in crowded wireless environments.

In advanced IoT testing, the TG44A supports sensors operating in the 24–44 GHz band, which are widely used in smart cities, industrial automation, and precision agriculture (e.g., 24 GHz radar sensors for object detection, 30 GHz environmental monitoring sensors). The TG44A generates precise test signals to verify the receiver sensitivity, signal-to-noise ratio (SNR), and transmission stability of these sensors. Its portability also allows for on-site testing in real-world IoT deployment environments, such as factories, farms, or urban infrastructure, ensuring sensors perform reliably under varying conditions.

3. Industrial Microwave System Validation

Industrial microwave systems, which operate in the 24–44 GHz frequency range, are critical for applications such as level sensing, material processing, and industrial communication. These systems require robust, stable performance in harsh industrial environments, and the TG44A provides the necessary signal generation capabilities for their validation.

For industrial microwave sensors (e.g., 24 GHz level sensors used in chemical tanks or grain silos), the TG44A generates stable microwave signals to test the sensor’s detection range, accuracy, and resistance to environmental interference (e.g., dust, moisture, and vibration). It can simulate different target distances and material properties, allowing manufacturers to validate the sensor’s performance under various operating conditions.

In industrial microwave communication systems (e.g., point-to-point links for factory automation), the TG44A tests the system’s signal transmission quality and reliability. It generates modulated microwave signals to verify the system’s ability to transmit data over long distances in industrial environments, ensuring minimal packet loss and low latency. The TG44A’s rugged design and ability to operate in a wide temperature range (-10°C to 55°C) make it suitable for use in harsh industrial settings, aligning with the operational requirements of these systems.

The TG44A’s exceptional signal fidelity, wide frequency coverage, and support for encrypted/anti-jamming signals make it a valuable tool for A&D applications.

For low-power military communication systems (e.g., tactical radios operating in the 30–44 GHz band), the TG44A generates encrypted signals to test the system’s security and anti-jamming capabilities. It can simulate hostile electromagnetic environments, including jamming signals of varying frequencies and power levels, to evaluate the communication system’s ability to maintain reliable connections under adverse conditions.

In UAV-borne RF sensor testing (e.g., radar sensors for surveillance or navigation), the TG44A generates high-fidelity radar waveforms (e.g., FMCW with large chirp bandwidths) to validate the sensor’s detection performance, range accuracy, and resolution. Its compact size and USB-powered design make it suitable for integration into UAV testing setups, both in the lab and in field trials. Additionally, the TG44A’s support for custom IQ waveform playback allows engineers to simulate real-world radar scenarios, ensuring the sensor performs effectively in mission-critical applications.
