The Rhode & Schwarz R&S CMW500 is designed to test user equipment for compliance with all wireless communications standards. The multistandard test platform’s R&S CMWcards test script development tool doesn’t require any programming experience, with a user interface that resembles a card game, according to the company. Simple rules let users quickly create functional tests or reproduce real network problems, R&S says.
R&S CMWcards provides a comprehensive pool of cards for the signaling currently used by the LTE and WCDMA standards, the company says. Users configure test scripts or parameterize protocol procedures by dragging and dropping the cards into a sequence. Card types include setup, procedures, the man-machine interface, and others. Their color coding is designed to ensure that created test sequences are always practical and useful.
A software wizard that uses the various user equipment states detailed in the 3GPP specification only shows the cards that put the device under test (DUT) into the desired protocol state. Once the user has finished creating the scenario, the test case can be executed immediately on the R&S CMW500.
R&S CMWcards targets complex applications such as throughput measurements, handover tests, inter-RAT procedures, and IMS VoLTE, including CS fallback (CSFB) and SRVCC. Like conventional protocol test cases, a message log collects the messages transmitted between the DUT and the network. The R&S CMWcards user interface can be added to the R&S CMW500 at any time.
