Today it is hard to imagine data exchange and instrument control without USB. No other interface has achieved such popularity for user equipment, electronic consumer goods and industrial products. As a result, the need for reliable, fast test solutions in development and integration has also increased. New software from Rohde & Schwarz makes the company's high-performance oscilloscope ideal for automated USB 2.0 compliance tests.   

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.
