AT A GLANCE

Modern mobile devices usually do not have an external

antenna connector. Connection to a radiocommunications

tester must therefore be made over the air. The link

between the device under test (DUT) and the test

equipment should be reliable and path losses kept to a

minimum. Interference from external radio sources should

be prevented as far as possible. The R&S®CMW-Z10 RF

shield box with the high-quality R&S®CMW-Z11 antenna

coupler together perfectly meet these requirements.

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.

The R&S®CMW-Z10 RF shield box with the R&S®CMW-Z11 antenna coupler clearly set standards. Offering

excellent shielding effectiveness and superior coupling characteristics, both devices can be used for

frequencies up to 6GHz. These outstanding features combined with a modular options concept make the

R&S®CMW-Z10 with R&S®CMW-Z11 indispensable for any radiocommunications tester.

As an aid to both opening and closing the

shield box, the R&S®CMW-Z120 option

provides an additional rotatable handle.

The antenna structure on the R&S®CMW-Z11 antenna

coupler board has been optimized to enable an excellent

radio connection between the DUT and the tester. The

highly broadband spiral antenna allows a wide variety

of applications. Further highlights of the R&S®CMW-Z11

include low coupling attenuation and the ability to place

the DUT at any desired position inside the box without

affecting attenuation caused by reflection.
