Debugging, stability tests and compliance measurements are key challenges when developing USB-capable electronic equipment. Before a product can display the USB logo, it must pass the USB Implementers Forum's compliance tests (USB-IF compliance program). Automatic USB test solutions that adhere to the USB-IF compliance program help manufacturers to pass these tests. Rohde & Schwarz meets this need with the R&S RTO-K21 USB 2.0 compliance test software for its R&S RTO high-performance oscilloscope. This software offers scenarios for testing USB 2.0 devices (DUT) when functioning as a device, host or hub. The different tests verify the signal quality, the exchange of data packets, the timing between the transmitter and receiver, the receiver sensitivity and much more.
The R&S RTO-K21 USB 2.0 compliance test software runs on a PC. It controls the oscilloscope and the DUT which is connected via a test fixture. Image-based instructions provide step-by-step support during the measurements. The automatically generated measurement report documents the test results: Users can add measurement details and screenshots and output the report in PDF, RTF or HTML format.
The R&S RTO-K21 USB2.0 compliance test software for automated compliance tests on USB interfaces and the R&S RT-ZF1 test fixture set are now available from Rohde & Schwarz.
