8 Series Sampling Oscilloscope TSO820 and TSO8C17/18 Datasheet Key features • • The 8 Series Sampling Oscilloscope provides a comprehensive optical test solution for telecom and datacom applications, as well as general purpose optical component testing. The TSO8C17 and TSO8C18 optical modules provide > 30 GHz optical bandwidth, plus fully integrated Optical Reference Receivers (ORR)1 enabling both single mode and multi-mode conformance testing at 850 nm, 1310 nm, and 1550 nm bands. Optical bandwidth above 30 GHz Single mode and multi-mode support for short and long wavelength optical testing Optical Reference Receiver (ORR)1 support for standard compliance testing 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. 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® • Optical modules • 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 userswappable current and future optical modules 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 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

TSO Series Sampling Oscilloscope Compliance testing Compliance test for 50G, 100G, 200G, and 400G IEEE 802.3TM standards such as 400GBASE-FR8, 400GBASE-DR4, and similar optical direct detect standards.
