TSO820 and TSO8C17/18

Key performance specifications

• Optical bandwidth above 30 GHz
• Single mode and multi-mode support for short and long wavelength optical testing
• Optical Reference Receiver (ORR)Optical Reference Receiver (ORR) is a 4th order Bessel-Thomson filter with a frequency response and tolerances as defined by the standards. Tektronix optimizes the response for best nominal fit and highest quality mask test results support for standard compliance testing

Applications

• Design/verification of High-Speed Components and Systems
• Signal integrity analysis
• Compliance test for industry PAM4 standards: 50G, 100G, 200G, 400G IEEE 802.3TM standanrd such as 400GBASE-FR8, 400GBASEDR4, and similar optical direct detect standards.

Key features

• New system architecture
  • Disaggregated: Separation of the acquisition hardware and software analysis allows the data to be streamed over Ethernet to a connected PC. Users have the capability to scale their analysis platforms to their needs and can connect from anywhere on the network
  • Configurable: The TSO820 mainframe supports user-swappable current and future optical modules

• Optical modules
  • Accurate testing and characterization of short or long wave optical signals using the high sensitivity and low noise performance of the TSO8C17 or TSO8C18 modules
  • Optical reference receivers (ORR)1 supports specified requirements for standards-mandated compliance testing
  • Extinction ratio measurements with built-in variable ER correction to ensure accuracy and repeatability

• Analysis with TSOVu®
  • TSOVu: A new software platform that runs independent of the oscilloscope mainframe on users’ computers or server for both live and post-processing of acquired data
  • TSOVu offers comprehensive analysis of PAM4 optical signals. Includes support for eye diagrams, optical measurements such as TDECQ, and other standard measurements
  • Measurement plug-in designed to interface with the base software that can be dynamically installed as needed

• High test throughput
  • Simultaneous capture of all channels at a high sample acquisition rate of 300 kS/s
  • Sophisticated Programmatic Interface (PI) for automation environments enables the highest test throughput. Each command supports full data synchronization, eliminating the need for wait / sleep statements

Applications

• Design/Verification of High-Speed Components and Systems
• Signal integrity analysis
• Compliance test for industry standards: 25G, 50G, 100G, 200G, 400G IEEE 802.3 standards such as 400GBASE-FR8, 400GBASE-DR4, and similar optical direct detect standards.
