Rohde & Schwarz CMW-Z14 (1204.7408.02)

The CMW-Z10 with CMW-Z11 is suitable for applications up to 6 GHz, thereby covering all common wireless standards such as GSM, UMTS, LTE, CDMA2000®, WLAN, Bluetooth® and GPS.

It offers high shielding effectiveness, so that the effects of external interference are reduced to a minimum.

The cover of the RF shield 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.

The CMW-Z10 has four module slots for different optional modules.

Available options currently include a 25-pole D-Sub feed through (CMW-Z12), a USB 2.0 feed through (CMW-Z13), a twin N connector (CMW-Z14), a 15-pole D-Sub feed through (CMW-Z15) and a LAN feed through (CMW-Z18) 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 be flexibly assigned. It is also possible to insert customer-specific modules.

Even large DUTs, such as tablets, can be accommodated.

The RF shield box provides ample space for positioning DUTs to minimize the coupling attenuation between the DUT and the tester.

The RF shield box is designed to withstand the harsh conditions encountered in service and manufacturing environments.

The closing mechanism has been optimized for ergonomic use, ensuring fatigue-proof handling while providing high quality results.

The CMW-Z16 second antenna option, a circular polarized second antenna element, makes it possible to test transmit diversity antennas and multiple input multiple output (MIMO) systems.

Mounted on the rear of the RF shield box, the CMW-Z16 allows radiated coupling of a MIMO DUT such as LTE MIMO 2x2.

The standard antenna provides a coupling field in a 90° direction to the second antenna element (CMW-Z16).

This provides the best coupling of MIMO devices in a near field environment.

The CMW-Z15 audio measurement option offers the accessories required for bidirectional audio measurements in the CMW-Z10.

The microphone and loudspeaker needed for the audio measurements can be optimally positioned within the RF shield box.

The audio signals are transmitted via a shielded D-Sub feed through to minimize the effects of external interference on the shield box's characteristics.

Audio signals are transmitted over the RF interface to a radio communications tester's audio code/decoder.

The audio path can be measured by comparing the original signal to the recovered signal.
