Rohde & Schwarz has introduced new test options for the R&S RTO2000 series oscilloscopes with a bandwidth of 6 GHz that support the 5 Gbit/s SuperSpeed USB and PCI Express (PCIe) 2.0 interfaces. There is also a new solution for USB power delivery (USB-PD).
The solution comprises: the R&S RTO2064 oscilloscope, the test options for the various interface standards, and modular R&S RT-ZM60 broadband probes for contacting the DUT. There are also the following new test options: triggering and decoding software options for SuperSpeed USB (USB 3.1 Gen1), PCIe 1.1/2.0 and USB-PD, plus a compliance test option for PCIe 1.1/2.0.
All the new triggering and decoding options support users looking for faults that occur during SuperSpeed USB, PCIe 2.0 and USB-PD transmission. The options trigger on user-defined protocol trigger events and decode the transmitted serial protocol, enabling the R&S RTO2000 to display additional time- and frequency-domain measurements time-correlated to the protocol trigger event. The cause of a fault is often recognizable at a glance.
The analysis results can also be displayed in a table with all protocol details and associated time stamps. The ability to analyze at different protocol levels is another important feature. For example, users can select between a simple bit view, a symbol view or a specific protocol view with frame start, address and data in order to track down protocol errors to the lowest bit level. Now developers have a powerful tool for fast analysis and debugging.
For PCIe, Rohde & Schwarz has expanded its compliance test suite to include compliance tests for PCIe 1.1/2.0. Software options based on the PCI-SIG standard post-processing analysis software assess the signal integrity against this standard. The test option permits automated compliance verification of the physical layer up to 2.5 Gbit/s.
