Wide frequency range up to 6 GHz
The R&S®CMW-Z11 antenna coupler is suitable for applications up to 6 GHz, thereby covering all common wireless standards such as GSM, UMTS, CDMA2000®, WLAN, LTE, WiMAX™, Bluetooth® and GPS.Sufficient space allows optimum positioning, even for large DUTs such as tablet PCs
DUTs can be placed virtually anywhere inside the RF shield box. Even large DUTs, such as tablet PCs, can be accommodated. The RF shield box provides ample space for positioning DUTs to minimize the coupling attenuation between the DUT and the tester.Designed for harsh, continuous duty and ergonomic operation
The R&S®CMW-Z11 antenna coupler are designed to withstand the harsh conditions encountered in servicing. The hinges and dampers are extremely robust. The aluminum case offers high resistance to distortion, ensuring precise closing of the box over time. The closing mechanism has been optimized for ergonomic use, ensuring fatigue-proof handling while providing high-quality results.Bidirectional audio tests
The R&S®CMW-Z15 audio measurement option offers the accessories required for bidirectional audio measurements in the R&S®CMW-Z10. The microphone and loudspeaker needed for the audio measurements can be connected and optimally positioned within the RF shield box. The audio signals are transmitted via a D-Sub feedthrough. This feedthrough is specially shielded to minimize the effects of external interference on the shield box's characteristics. Audio signals applied via the loudspeaker are picked up by the DUT's microphone and transmitted over the RF interface to a radiocommunications tester. The tester uses a voice decoder to recover the audio signal and compares it to the original signal. To test the audio path with the DUT's loudspeaker, the tester generates an audio signal and sends it to the DUT via the RF interface. There, the audio signal is recovered and picked up by the microphone included with the R&S®CMW-Z15 option. Again, the audio path can be measured by comparing the original fed-in signal to the recovered signal.
