3. Key Features

3.1 Extended Frequency Coverage for mmWave Applications

The VSG60A covers 9 kHz to 60 GHz, enabling comprehensive testing across conventional RF bands and critical mmWave spectrums (e.g., 5G FR2, 77/81 GHz automotive radar, Ka/Q/V-band satellite communications). It maintains stable performance and consistent signal quality across the entire frequency range, eliminating the need for multiple specialized signal generators.

3.2 High Real-Time Bandwidth for Wideband Signals

With a 2 GHz RTBW, the VSG60A generates high-fidelity wideband signals required for modern standards and complex systems. It supports 5G FR2 signals with 400 MHz channel bandwidth (per 3GPP) 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 (<-50 dBc typical) ensure precise signal generation, critical for testing sensitive receivers and characterizing RF components (amplifiers, filters, mixers). High power accuracy guarantees reliable and repeatable test results.

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 7, and automotive radar simplify setup for common testing scenarios. The 16 GSamples waveform memory enables playback of pre-recorded real-world signals for realistic scenario simulation.

3.5 Compact, Portable Design

USB-powered and lightweight (1.2 lbs), the VSG60A is ideal for field testing (e.g., 5G FR2 base station deployment, outdoor radar propagation studies) where traditional benchtop equipment is impractical. Its rugged enclosure withstands transportation and harsh testing environments.

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). 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.
