W1902 Digital Modem Library

Data Sheets

The W1902EP/ET Digital Modem Library is a simulation add-on for SystemVue that enables transmit, receive, and Bit-Error-Rate (BER) analysis for 40 digital modulation formats used in satellite, military and commercial wireless communication systems. Additionally, the W1902 provides framing, Direct-Sequence Spread Spectrum (DSSS), and reference receiver designs for 25 of the linear and phase modulation formats. The library enables higher design productivity, reduces verification effort, and supports a model-based design approach across the entire communications design cycle—from algorithm to implementation to hardware verification—using wideband test equipment.

Productivity and flexibility for A/D applications

Even though military and satellite communication networks are being upgraded to newer high-capacity and low-latency formats, many communication designers continue to invest project overhead time to maintain personal simulation blocksets and tools.

  • The W1902 Digital Modem Library reduces this overhead and streamlines the verification effort by providing a reliable, Commercial Off-the-Shelf (COTS) reference for common modulation formats.
  • The W1902 also connects easily to test equipment and other RF design tools, which enables the higher level of system simulation accuracy needed for RF/FPGA co-design, digital pre-distortion, and test equipment support for today’s wider bandwidths.
  • SystemVue enables the easy import of intellectual property in C++, MATLAB, and HDL formats, allowing the additional modeling details required by classified, secure and academic research applications to be easily accommodated.

Who should use the SystemVue Digital Modem Library?

System-level architects, baseband algorithm designers, and RF component designers can use the W1902 Digital Modem Library to perform early R&D validation of communication system architectures, components and DSP algorithms. The W1902 also provides a convenient modeling platform for custom applications and proprietary communication links.

The SystemVue environment is also scriptable, links to RF design tools such as Keysight Technologies, Inc. Advanced Design System (ADS), and connects to high-performance test equipment, providing both flexibility and consistency across a full product lifecycle.

Key applications

  • Satellite communication, including ground-space, space-space and deep-space
  • Military communication and secure backhaul
  • Academic research
  • Extended test equipment support for specialized modulation formats
  • Component validation, using either simulation or the latest wideband test equipment

Key benefits

  • Higher productivity, through a trusted IP reference on an open modeling environment
  • Lower project overhead, scripting, verification, and NRE
  • Faster time to deployment, through superior RF-DSP co-design in SystemVue

Complementary Keysight software (such as Keysight I/O libraries, Command Expert, and the 89600 VSA with option 300) is often used to connect SystemVue to families of Keysight test equipment, including AWGs, digitizers, RF sources, RF analyzers, and others. SystemVue offers a convenient modeling and verification platform that can be used in the R&D environment, in the test lab, or shared over a network.
