3. Key Features

3.1 Extended Frequency Coverage for Mid-to-High Band Applications

The TG44A covers a wide frequency range from 9 kHz to 44 GHz, enabling comprehensive testing across conventional RF bands and critical mid-to-high frequency spectrums (e.g., 5G sub-6 GHz, Wi-Fi 6/7, 24 GHz industrial microwave, 30–44 GHz emerging IoT bands). It maintains stable performance and consistent signal quality across the entire frequency range, eliminating the need for multiple specialized signal generators and simplifying test setups for diverse applications.

3.2 High Real-Time Bandwidth for Wideband Signal Generation

With a 1 GHz real-time bandwidth (RTBW), the TG44A generates high-fidelity wideband signals required for modern wireless standards and complex systems. It supports 5G sub-6 GHz signals with 400 MHz channel bandwidth (per 3GPP specifications) and wideband radar waveforms (e.g., FMCW with large chirp bandwidths), ensuring minimal distortion for accurate simulation of real-world operating conditions.

3.3 Exceptional Signal Fidelity

Ultra-low phase noise and low harmonic distortion (<-55 dBc typical) ensure precise signal generation, critical for testing sensitive receivers and characterizing high-frequency RF components (amplifiers, filters, mixers). High power accuracy guarantees reliable and repeatable test results, even at the upper end of the 44 GHz frequency range.

3.4 Comprehensive Modulation Capabilities

Supports a full suite of analog and digital modulation formats, as well as custom IQ waveform playback. Pre-defined templates for 5G NR, Wi-Fi 6/7, and industrial microwave protocols simplify setup for common testing scenarios. The 8 GSamples waveform memory enables playback of pre-recorded real-world signals for realistic scenario simulation, such as complex interference environments or real wireless traffic.

3.5 Compact, Portable Design

USB-powered and lightweight (1.5 lbs), the TG44A is ideal for field testing (e.g., 5G base station deployment verification, outdoor IoT network testing) where traditional benchtop equipment is impractical. Its rugged enclosure withstands transportation and harsh testing environments, ensuring reliability in both lab and field settings.

3.6 Seamless Integration with Spike Software

Fully integrated with Signal Hound’s Spike RF analysis software, providing a unified interface for signal generation and spectrum analysis (when paired with Signal Hound spectrum analyzers such as SM435C). Spike offers intuitive tools for signal configuration, waveform editing, and real-time monitoring. Support for Signal Hound’s SDK enables custom automation in Python, C/C++, or .NET.
