Features
Wide frequency range up to 6 GHz
Both the R&S®CMW-Z10 RF shielding box and the
R&S®CMW-Z11 antenna coupler are suitable for applications
up to 6 GHz, thereby covering all common wireless
standards such as GSM, UMTS, WLAN, LTE, WiMAX™,
Bluetooth® and GPS. The R&S®CMW-Z10 RF shielding
box 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.
Ultra-low reflections
The cover of the R&S®CMW-Z10 RF shielding box 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. 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.
Modular options concept and flexible assignment of modules
The R&S®CMW-Z10 RF shielding box has four module slots for different optional modules. Available options currently include a D-Sub feedthrough (R&S®CMW-Z12), a USB feedthrough (R&S®CMW-Z13) and a twin N connector (R&S®CMW-Z14). 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
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-Z10 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 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.
