Features

Wide frequency range up to 6 GHz

The R&S®CMW-Z11 antenna coupler are suitable for applications up to 6 GHz. This covers all common wireless standards such as GSM, UMTS, WLAN, Bluetooth® and GPS.

Ultra-low reflections

With the R&S®CMW-Z10 RF shielding box, the DUT can be positioned anywhere on the R&S®CMW-Z11 antenna coupler with virtually no effect on attenuation caused by reflection.

Sufficient space allows optimum positioning, even for large DUTs such as tablet PCs

DUTs can be placed virtually anywhere inside the RF shielding box. This means that even large DUTs, such as tablet PCs, can be accommodated. The RF shielding box also provides ample space to position DUTs so that the coupling attenuation between the DUT and the tester is minimized.

Designed for harsh, continuous duty and ergonomic operation

The R&S®CMW-Z11 antenna coupler are designed to withstand the harsh condi-tions 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 a long term. The closing mechanism has been optimized for ergonomic use. This ensures fatigue-proof handling while providing high-quality results.

Bidirectional audio tests

The R&S®CMW-Z15 option offers the accessories required for bidirectional audio measurements in the R&S®CMW-Z10 shielding box. The microphone and loudspeaker needed for the audio measurements can be connected and optimally positioned within the RF shielding 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 shielding 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.
