Test Platform Series Enhances Capabilities Of 2G And 3G Wireless Testing
Aeroflex has released the PXI 3000 series modular test platform with supplementary communications standards, designed to allow communications test engineers to concentrate on a range of 2G and 3G wireless data standards using a single, flexible, software-defined system, according to the company. Aeroflex believes its addition of the new Bluetooth measurement suite and WLAN, CDMA2000/1xEVDO plug-ins for the PXI Studio software application and upgraded WiMAX, UMTS, and GSM/EDGE enhance the system’s versatility.
The company’s PXI Studio application software supports all of these management suites, in the hopes of facilitating test system integration, in addition to production- and R&D-related testing and problem solving. The Bluetooth measurement suite features quick measurement of signal characteristics such as burst power, spectrum, and modulation accuracy, says Aeroflex. Both Bluetooth and Bluetooth enhanced data-rate (EDR) radio signals are characterized with the 2008 Bluetooth Specifications 1.2/2.0/2.0 + EDR/2.1/2.1 + EDR revision 2.1E1 as well.
The CMDA2000 and 1xEVDO reverse link measurement suite is designed for PXI-based RF test systems in mobile radio transmitter creation, submodules, and radio-frequency integrated circuits (RFICs). In addition to providing precise characterization of CDMA2000 rev C and 1xEVDO rev A reverse link transmissions, they also offer phase and amplitude error measurements with the PXI Studio plug-in.
Aeroflex asserts that IEEE 802.11a/b/g finds extra support from the new WLAN Measurement Suite with its data rates, corresponding modulation, and encoding formats up to 54 Mbits/s. Features such as carrier leak, skew, and gain imbalance are available with DSSS-OFDM support. According to the company, the measurement suite is perfect for smart-phone tests, as it can test multiple standards at once and save time.
With its ability to simplify programming and PXI integration into automated test applications for GSM handsets and devices, the GSM/EDGE has been refurbished with a frequency lock range up to 300 kHz, which enables it to test terminal transmissions while unsynchronized to a downlink (DL) signal, says Aeroflex.
Designed to conduct high-speed RF measurements on user equipment (UE) radio transceivers, sub-assemblies and RF components during R&D, design verification, manufacturing test and quality control, the UMTS Uplink Measurement Suite currently sustains phase discontinuity, IQ skew, gain imbalance, carrier leak, and phase/amplitude error.
Combined with the PXI 302xC, the suite supports receiver bit-error rate (BER) sensitivity testing in loopback and “drive to level,” allowing control of the device under test (DUT) output power from the tester.
Enabling WiMAX physical layer (PHY), orthogonal frequency-division multiple access (OFDMA) power, and spectrum and modulation measurements consistent with IEEE 802.16e (2005), the WiMAX measurement has received updates including user-defined SEM, IQ skew, gain imbalance, and carrier leak.
Available at the end of July are the GSM/EDGE Measurement Suite (3030 option 100), the UMTS uplink measurement suite (3030 option 101), the CDMA2k/1xEV-DO measurement suite (3030 option 102), the WLAN measurement suite (3030 option 103), the WiMAX measurement suite (3030 option 104), and the Bluetooth measurement suite (3030 option 106). Current PXI customers can obtain free software updates from the Aeroflex Web site, while new customers can find more information by e-mailing firstname.lastname@example.org.
