Rohde & Schwarz CMW-B510F module

Rohde & Schwarz has introduced a fading simulation module for its CMW500 wideband radio communication tester.

It is now possible for smartphone or chipset manufacturers to carry out standard-compliant MIMO performance tests during LTE testing, for example.

Only a single instrument is required for these tests, which minimises space requirements and set-up effort. In addition, the module supports the GSM and WCDMA standards.

When using conventional solutions to perform tests with realistically simulated propagation conditions, an additional instrument is needed for fading simulation.

This additional instrument requires extra cabling and separate configuration in addition to level and delay correction. In contrast, the CMW-B510F module is integrated into the tester and configured directly from the menu. This simulates the dynamic propagation conditions as defined in the test cases of the 3GPP standard for LTE, WCDMA, HSPA, HSPA+, GSM and EGPRS.
