WCDMA conformance tester switches to R and D
In addition to WCDMA conformance testing, the R and S CRTU-W from Rohde and Schwarz can now also be used for signalling tests in research and development.
Testers support new digital TV standard
Rohde and Schwartz produces both operating equipment and test instruments for new DVB-H digital TV standard.
The RF test chambers can optionally be expanded to provide additional test capabilities, such as audio tests.
Featuring high shielding effectiveness, the RF test chambers promise interference-free performance and so can aid reproducible tests in accordance with a wide variety of radio standards including ISM, GSM, CDMA, UMTS, WLAN, Bluetooth and many more.
The wider R and S TS7123 model was specially designed for larger devices, such as automotive applications.

Rohde and Schwarz has developed the first package of test scenarios to test interoperability between the NTT DoCoMo network and third-generation mobile radio phones.
Log-periodic antenna covers a big band
The HL033 is a linearly polarised log-periodic antenna suitable for general transmission and reception applications in the frequency range from 80MHz to 2 GHz.
It can be used for production tests on the RF interfaces of car radios and infotainment systems.
The automatic R and S TS712xA version is ideal for use in a production environment.
Used in conjunction with the R and S CMU200 universal radiocommunications tester or other test equipment as well as suitable antenna couplers for GSM, WCDMA and UMTS, the RF test chambers enable BER, FER and power measurements on mobile phones, for example.
They also provide RF tests on other small devices that have a radio interface, such as on PDAs, remote keyless entry devices or cordless phones that operate in the ISM, WLAN, home RF or Bluetooth bands, for example.
The R and S TS712xA RF automatic test chambers have been designed to meet the requirements of automated production lines.
These include long service life, rugged design and automatic opening and closing of the RF chamber.
The valves for opening and closing are controlled via a 24V connector or an optional USB control.
The interior of the RF test chambers may optionally be lined with absorbent material, which attenuates high-frequency electromagnetic waves and thus ensures reproducible and stable measurements.
The absorbent material also works in the audio range, where it effectively reduces reflections and ambient sound.
GSM and Bluetooth antenna couplers are available in the range 800MHz to 2.4GHz; the couplers can be attached to the side panels or the bottom panel.
Moreover, ISM couplers for frequencies below 1GHz and WLAN antenna couplers for 2.4 to 5.8GHz are available that can be adapted for use with the RF test chambers.
The RF test chambers are sealed by means of a milled cover, which is fastened in place with easy-to-lock tension levers.
Optionally, elevated covers are available that provide sufficient room for the integration of further test equipment such as CCD cameras or keyboard stimulators.
The R and S TS712xM manual version is equipped with a handle that allows easy closing and locking of the RF test chamber.
The manual version is mainly intended for use in service and development.
The automatic and the manual versions R and S TS712xA and R and S TS712xM of the RF test chambers have the same basic design, ensuring the same test functionality in development, production and service. Request a free brochure from Rohde and Schwarz ...
