Compliance testing

Compliance test for 10G, 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 signal acquisition and analysis in the same instrument. However, as the instrument ages, the relative processing power becomes obsolete over time. The 8 Series Sampling Oscilloscope turns this notion upside-down and features a disaggregated architecture, which separates the acquisition hardware and analysis platform. TSOVu can be installed on any Windows machine, giving users 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, users can scale or change capabilities to match changing testing needs without sending the instrument in for factory reconfiguration.

Changes of the mainframe hardware configuration are reflected by the connected software application (TSOVu). The module type, serial number, calibration information, and so on are accessed via TSOVu GUI 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 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 Mainframe to acquire multiple channels simultaneously and analyze remotely over Ethernet or Wi-fi.

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

Adjust vertical channel parameters individually based on the modulation type, channel bandwidth, and inherent signal characteristics like offset, skew, or external attenuation as shown:

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.

Native NRZ mask and measurement

Although the industry has started its transition to PAM4 modulated signals, NRZ/PAM2 has remained a prominent medium for high speed ethernet communication. Tektronix’ TSOVu delivers a streamlined NRZ measurement and mask testing experience. Measurements such as TDEC, VECP, mask margin, mask ratio, and other common measurements are available alongside industry standard and custom masks. Since all NRZ measurement and mask testing are included in TSOVu as a base feature, these capabilities are available at no charge to the user.

TSO820 EN US 85W 61589 03

Math expressions and sources

With built-in Math features, TSOVu users can take advantage of simple scaler waveform operations or construct complex math expressions to increase productivity and device insight. Using the expression editor, users can add/subtract, multiply/divide, create eye diagrams, and even perform complex optimization / equalization with a single math source.

Supported math operations include:

  • Addition / Subtraction / Multiplication / Division
  • Unit Interval Overlay from Pattern Sync waveforms (eye diagrams)
  • Waveform resampling
  • Feed Forward Equalization (FFE)

Where applicable, all math output sources can be used for additional measurement, mask testing, and histogram data collection.

High-sensitivity operation accommodates low amplitude 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.

Measurement report and data management

TSO820 EN US 85W 61589 03

TSOVu supports several methods of sharing work critical data through the use of measurement reports and session files. Create detailed reports automatically in TSOVu and include information pulled from active analysis, plots, and system configuration. Reports can be set up to include complete system details and analysis, or summarized in a per channel brief. For an interactive look at historic data, session files (*.tss) enable full recall of waveform data, scope configuration, and measurements for further analysis. Measurement reports and session files are modern approaches to saving data and measurement results; however, waveform data can still be stored in other accessible formats, such as csv.
