8 Series Sampling Oscilloscope

Read Online:

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.

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

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. The TSO820 Sampling Oscilloscope is also designed to support high speed NRZ standards such as 100 Gb Ethernet (100GBASE-LR4 or similar) that operates at a rate of 25.78125 Gb/s. Stay up-to-date on the latest standards changes by updating or adding new measurement plug-ins as they are released.

Disaggregated architecture

Traditional oscilloscopes perform measurements on-device with the specific processor that the instrument was shipped with. However, that processor becomes obsolete over time, and makes speed upgrades to the analysis platform impossible. The 8 Series Sampling Oscilloscope turns this notion upside-down and features a disaggregated architecture, which means that the acquisition hardware and analysis platform have been separated. Since TSOVu can be installed on any Windows 10 machine, users now have the freedom to choose the laptop readily available in the lab, a server connected to the network, or anything in between.

Flexibility by design

The 8 Series Sampling Oscilloscope has been designed with modularity in mind. The TSO820 mainframe features the two module slots that are compatible with TSO8C17 and TSO8C18 optical modules, as well as future other modules. The oscilloscope mainframe can be reconfigured on the spot by removing or inserting modules through the top of the instrument. As testing requirements evolve, scale or change capabilities to match current testing needs without sending the instrument in for factory reconfiguration.

When connecting to the TSO820 using TSOVu, any changes to the hardware configuration will be reflected by the user interface . The module type, serial number, calibration information, and so on are accessed via TSOVu or PI queries.

User interface

The 8 Series Sampling Oscilloscope features a brand-new sampling oscilloscope software architecture called TSOVu. This new software runs on a user's external Windows 10 PC and features an intuitive user interface and analysis engine for increased measurement throughput and limits oscilloscope downtime.

The communication between the PC running TSOVu and the TSO820 mainframe is based on an IEEE 802.3TM Ethernet network, such as 100BASE-T or 1000BASE-T. TSOVu's Programmatic Interface (PI) commands can be used in the automation environments to control instrument functionality and analysis reporting. Use TSOVu with the TSO820 Sampling Oscilloscope Mainfarme to acquire multiple channels simultaneously and analyze remotely over Ethernet or Wi-fi.

Wi-fi requires consistent and stable network connection for proper use.

Add reference waveforms for offline processing of previously captured data, view eye diagrams before and after TDECQ FFE equalization, and detach windows from the base software to be rearranged or resized

Measurement plug-in interface

Using the flexible plug-in architecture in TSOVu, measurement plug-ins that can interface with TSOVu will display directly in the Add Measurement window. This includes Tektronix’ standard Pulse Measurement and PAM4 Optical Measurement plug-ins, and enables quick development of custom measurement libraries that are fully integrated in TSOVu to be called from the user interface or through PI commands.

High-sensitivity operation accommodates lowamplitude signals

The TSO8C17 and TSO8C18 optical modules feature high input sensitivity for measurement of low power signals. This enables the user to recover full pattern acquisitions with little noise contribution from the oscilloscope, making it possible to take true and accurate measurements in conditions where signal power is low.

Software

TSOVu is available for download at https://www.tek.com/downloads

Software licenses for TSOVu are available for purchase to extend the analysis capabilities of the base oscilloscope software. The Pulse Measurement Plug-in is available free with every TSOVu; other measurement plug-ins can be enabled for operation with purchase of a valid license.

Software licensing and activation information

Optional plug-ins for TSOVu require installation of a valid license before initial use. Each software enabled feature requires its own license, and licenses can be managed within the Tektronix Asset Management System (Tek AMS). Product license management requires a login account and can be accessed via the Tek AMS web site address (https://www.tek.com/products/product-license).

There are four types of licenses available for plug-in applications which are explained below:

  • NLP: Node-locked perpetual licenses enable oscilloscope features permanently, are assigned to the Host ID of an instrument or TSOVu software, and guarantee software updates for the first 12 months. Software updates after the first 12 months are available with 1-year renewal.
  • FLP: Floating perpetual licenses enable oscilloscope features permanently, can be transferred between Host IDs (mainframe or software), and guarantee software updates for the first 12 months. Software updates after the first 12 months are available with 1-year renewal.
  • NL: Node-locked subscription licenses enable oscilloscope features for a predefined time period, are assigned to the Host ID of an instrument or TSOVu software, and guarantee software updates for the duration of the license.
  • FL: Floating subscription licenses enable oscilloscope features for a predefined time period, can be transferred between Host IDs (mainframe or software), and guarantee software updates for the duration of the license.
Use the Tektronix Asset Management system to check in and check out floating licenses.
