Rohde & Schwarz adds WLAN signaling functions to its R&S CMW500 and R&S CMW270 multistandard test platforms

To achieve optimal results, WLAN user equipment needs to be tested under realistic operating conditions. The R&S CMW500 wideband radio communication tester and the R&S CMW270 wireless connectivity tester now have new options for accomplishing this task: In signaling mode, they can emulate a WLAN access point in line with IEEE 802.11a/b/g/n.

Mobile World Congress, Barcelona 2012- February 27, 2012- (Virtual Press Office) — Rohde & Schwarz offers manufacturers of mobile devices and consumer electronics two universal test platforms: the R&S CMW500 and the R&S CMW270. The R&S CMW500 covers all common cellular and non-cellular standards, while the R&S CMW270 has been customized for non-cellular standards. New options now provide additional WLAN signaling functions.

Manufacturers of WLAN components for smartphones, tablet PCs and laptops can use the R&S CMW500 and the R&S CMW270 during development to test the functionality and performance of their products and to conduct transmitter and receiver tests. Thanks to configurable test parameters, developers consistently obtain comparable and reproducible results that create the basis for objective analysis. Signaling mode measurements are now considerably easier: The testers exchange protocol information with the DUT to control the DUT's settings, eliminating the need for the separate control software previously required for some chipsets.

The signaling mode provided by the new options allows developers to test the transmitter of WLAN user equipment as well as the quality of a receiver under realistic operating conditions. The testers measure the data throughput of WLAN components precisely and reproducibly – in both receive and transmit mode. The protocol stack can also be analyzed to optimize the message flow between access point and user equipment.

The WLAN function is further proof of the versatility of these unique, expandable Rohde & Schwarz test platforms. The new options are perfect for manufacturers of mobile user equipment who already use an R&S CMW500 in development. They can use their R&S CMW500 to measure other wireless standards as well. It is also the ideal test solution for manufacturers of WLAN products who put quality first. The versatile R&S CMW test platforms can be used as stand-alone instruments for transmitter and receiver measurements or as part of a complex type test system.
The new options for WLAN in signaling mode for the R&S CMW500 and R&S CMW270 test platforms are now available from Rohde & Schwarz.
