Brief Description

The R&S®CMW-Z10 RF shielding box clearly sets new standards: Offering excellent shielding effectiveness and superior coupling characteristics, the R&S®CMW-Z10 can be used for frequencies up to 6 GHz. These outstanding features combined with a modular options concept make the R&S®CMW-Z10 indispensable for any radiocommunications tester.

The R&S®CMW-Z10 is made of solid aluminum. It is firmly closed by means of a lever handle with a defined stop. The bottom and cover will not distort under normal conditions. This ensures uniform compression of the sealing cords provided around the entire box – an important prerequisite for effective RF shielding. The cover is lined with absorber material, which minimizes reflections.

Features & Benefits

  • Wide frequency range up to 6 GHz

    The R&S®CMW-Z10 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. The R&S®CMW-Z10 offers high shielding effectiveness, so that the effects of external interference are reduced to a minimum. The R&S®CMW-Z110 RF cable also provides excellent shielding for frequencies above 4 GHz.

  • Ultralow reflections

    The cover of the R&S®CMW-Z10 is lined with absorber material in order to minimize reflections. Strong reflections would cause a significant variation in attenuation as a function of the DUT position. The DUT can be positioned anywhere on the antenna coupler with virtually no effect on attenuation caused by reflection.

  • Modular options concept and flexible assignment of modules

    The R&S®CMW-Z10 has four module slots for different optional modules. Available options currently include a 25-pole D-Sub feedthrough (R&S®CMW-Z12), a USB feedthrough (R&S®CMW-Z13), a twin N connector (R&S®CMW-Z14) and a 15-pole D-Sub feedthrough (R&S®CMW-Z15) for bidirectional audio testing. All modules are optimized so that their effect on shielding characteristics is kept to a minimum. The module slots are identical, allowing each module to be inserted into any slot. The optional connectors can thus be flexibly assigned. It is also possible to insert customer-specific modules.

  • 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-Z10 RF shield box is 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 highquality 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.

  • Antenna diversity and MIMO tests

    Mobile devices and wireless networks use multiple antenna concepts to benefit from diversity gain and enhance the signal to noise ratio or to exploit the spatial multiplexing scenario of the radio channel to offer users significantly more data capacity. The R&S®CMW-Z16 second antenna option, a circular polarized second antenna element, makes it possible to test the limits of wireless communications and benefit from transmit diversity antennas and measurements of the data throughput increase provided by multiple input multiple output (MIMO) systems.

    Mounted on the rear of the RF shield box, the R&S®CMW-Z16 allows radiated coupling of a MIMO DUT such as LTE MIMO 2x2. In applications like these, the standard antenna provides a coupling field in a 90 ° direction to the second antenna element (R&S®CMW-Z16). This provides the best coupling of MIMO devices in a near field environmentand eliminates the need for using RF cables to connect the DUT to a wireless communications tester like the R&S®CMW500.
