An option for fading is now available for the vector signal generator R&S SMU200A. Two independent RF fading paths with digital modulation simplify applications such as the performance tests defined in 3GPP. With a time resolution of up to 10 ps, a bandwidth of 80 MHz, and a total of 40 fading paths, the instrument covers a frequency range of 100 kHz to 6 GHz and includes all conventional wireless standards such as GSM, WCDMA, CDMA2000 and WLAN.
Wenzel Associates has released low jitter phase noise sources featuring Blue Tops technology for operating and testing new components and systems. Such applications include radar local oscillators, communications systems, phase noise measurement systems and low jitter clocks for testing data converters and other high performance semiconductors. These systems often require a source that provides several frequencies at a time with virtually no spurious content and high quality phase noise.
Agilent's one-box test set measures both WLAN 802.11a/b/g and Bluetooth modules from a single platform. The N4010A wireless connectivity test set with WLAN option 102/103 combines a fully calibrated vector signal generator and wide bandwidth signal analyser into a single test set, maximising manufacturers' flexibility and eliminating the need to purchase separate WLAN and Bluetooth measurement systems.
Anritsu has introduced the MD8470A signalling tester, designed to enable the wireless communications industry to rapidly develop and deploy new services and applications onto next-generation mobile phones. The tester provides a complete 'network simulator on the desk' allowing developers to test new features, services and applications on real handsets in a live environment with the convenience of a desktop test unit.
Agilent has introduced a class of instrument that can evaluate the critical performance characteristics of nearly all types of RF and microwave signal sources. The E5052A signal source analyser (SSA) replaces a large, complex rack of test equipment with a single instrument that speeds measurement times by a factor of 10.
In the last of a three-part series on interference in wireless systems, we look at all the different types of potential interfering signals and how to identify them
The Atlas LCR passive component analyser from Peak simplifies the testing of passive components.Traditional LCR bridges are inherently complex and very time consuming to use. This analyser does everything automatically, it tells the user the component type in addition to component value data. What's more, it automatically selects the best signal level and frequency for the particular component under test.
The CEA-MOUNT Illuminator is an active phased array Continuous Wave Illuminator (CWI) that integrates with ship combat systems to provide target illumination and missile uplink for semi-active homing missiles (SM-2/ESSM).
Poseidon Scientific Instruments (PSI) has released the 5 MHz to 1 GHz receiver OR-102A for use with its ODIN-320A phase noise analyser. The receiver enables engineers to perform automated phase noise measurements at low frequencies on quartz crystal and surface acoustic wave (SAW) oscillators. Moreover, the residual noise of amplifiers, or any two port device, can be automatically measured in combination with PSI's upcoming delay line device.
Vicom has expanded the functionality for the 2975 Radio Test Set for Project 25 (P25) testing from IFR, a designer of advanced test solutions that include wireless radio test sets, signal sources, avionics and frequency agile test, microwave test, signal analysers and ATE (automated test equipment).
B&K Precision Corporation has released the Model 2650, a handheld, PC-com-patible 3.3 GHz spectrum analyser. Weighing only 1.8 kg including battery, this compact, versatile, portable unit is suitable for use in the evaluation of W-CDMA, CDMA, GSM, PDC, PHS, Wireless LAN, 802.11 and Bluetooth systems.
