Model SM-5320
Data/Waveform Generator/Tester for Vector Modulation
Flexible Multi-Mission Solution for Signal Generation/Test

Applications

  • Integrated Programmable Waveform Generator, Noise Generator, and BER Test System with Optional Modulator
  • Link and Range Setup, Testing and Operation
  • SatCom Science, and Military Missions
  • SGLS and STDN Ground Stations
  • Mobile Tracking and Data Systems
  • Payload and Product Integration, Simulation and Testing
  • Beacon Modulator with Gold Code Support, Beacon Suitcase and Test Suites
  • Supports ARTM PCM/FM and SOQPSK

The SM-5320 is a versatile data and waveform generator, providing fully programmable data and signal processing and advanced waveform creation. The digital implementation provides for the small form/fit of this product while fully satisfying applications requiring ruggedized packaging, minimum power consumption, and high spectral purity. The standard design supports a multitude of digital or analog modulations, or complex combinations of modulation formats.

Data generation, coding, and modulation can be driven from a variety of external digital inputs or via internal pattern and waveform generation sources. Dual data processing paths are included to allow creation of independent I and Q streams.

The design also supports link test and verification applications. A single SM-5320 can replace a BERT, waveform generator, noise source, attenuators, power meter, and spectrum analyzer. Combining these capabilities in one small, simple to use unit allows quick and accurate setup and testing without in-depth system knowledge.

The SM-5320 can provide a low frequency IF output (up to 20 MHz) or may be provided with an optional fixed frequency embedded vector modulator (70 MHz, 140 MHz, or custom). Independent in-phase and quadrature analog outputs can also be utilized to drive an external vector modulator or signal.

Up to 32 Configuration Profiles can be stored with user-defined link names and recalled with a single command, simplifying fast and accurate configuration changes.

Configurable front panel BNC connectors provide operators with ready access to internal operating signals. The SM-5320 can also optionally support a station clock input for external frequency reference.

The firmware-intensive implementation of the SM-5320 readily accommodates custom features and signal processing tasks. Using the latest generation digital signal processing techniques allows upgrades via firmware changes, even for previously fielded systems.

The SM-5320 Data/Waveform Generator  is available in a standard 1U 19 inch rack mountable chassis or as PCI cards and API for integration into other systems. The Chassis version is not based on a PC platform, avoiding the requirement for 3rd Party Operating Systems and hard drives and reducing the need for system patches and IT security concerns.
