SPECTRUM FIDELITY™️ Next Generation RF Emulation and Capture System

The Spectrum Fidelity ZX™️, is the next generation of Emulation and Capture (EAC) Systems from Acquired Data Solutions (ADS).  Spectrum Fidelity ZX™️ represents a significant leap in technology and software capacity. The system is a highly flexible and configurable system that represents the confluence of NI hardware, RADX Technologies software and ADS offerings and integration. ADS closely follows new product liens and life-cycle planning for RF Playback (emulation) and Record (capture) products to introduce new features and capabilities desired in the RF environment.

Key Features

  • Incorporation of the RADX® Technologies (RADX) Liberty GT® COTS, software-defined, synthetic, modular, integrated RF measurement science framework and software (MSFS) Suite as the software engine. This software platform has app-driven modules and touch-screen implementation for improved ease of use and application flexibility.
  • Integration of the National Instruments (NI) VST 2.0 (Pxle-5840) RF transceiver provides advanced, Real-Time RF playback and record capabilities to 1 GHz instantaneous bandwidth performance level. The system operates as a stand-alone playback (emulation), stand-alone record (capture) or dual-mode configuration. The Spectrum Fidelity ZX™️ System may also be configured with any of the NI VSA and VSG products.
  • Additional of Real-Time full bandwidth signal processing capability applicable to one or more channels simultaneously. This powerful new feature is fully customizable.

Operational Environments that will benefit from a Spectrum Fidelity ZX™️


The versatility & power to address the complexities involved with radar development and test.

Electronic Warfare

The configuration versatility & real-time processing enables our system to address a broad range of EW application.

Security System

The ability to record in harsh environments and test systems via RF playback are paramount to security.

Interference Analysis

The ability to record with a trigger in a single or multi-channel allows clients to understand the nuances of the environment their RF device is encountering.

How it Works

Complete end to end testing of complex signal processing systems as well as field testing of simple receivers are significantly benefitted by the ability to capture and playback or emulate real world environments. RF receiver testing requires complex hardware and software with the ability to generate signals at the limits of the receiver’s capabilities. At ADS we have developed a family of record and playback units for the range of the spectrum from below 20Hz to above 28GHz. Our product offerings, under the umbrella of Spectrum Fidelity ZX™️ range from single channel record or playback units to eight (8) multi-channel phase synchronized units extendable to 3, 64 channels and beyond to emulate complex environments for large signal processing systems. We combine National Instruments Hardware with a comprehensive Software Suite and RF Playback/Record Tool kit to create a COTS out of the box experience.
