Expanding its PXI family, Aeroflex has announced a new modular RF test platform for wireless applications up to 6 GHz. Consisting of three modules, a chassis/controller, and measurement software, the platform is designed to handle engineering tasks from research and development to production test in cellular, wireless data, RFIC, and military/aerospace applications.
In terms of RF measurement modules, the new release includes the 3025C, a 1 MHz to 6 GHz digital signal generator; 3030C, a 250 kHz to 3 GHz wideband RF digitizer; and 3035C, a 250 kHz to 6 GHz wideband RF digitizer. Fleshing out the company's PXI portfolio, these new releases extend the frequency range coverage and analysis bandwidth of previous offerings. For instance, the analysis bandwidth is 90MHz, which nearly triples the bandwidth available in the 3030A (33MHz).
The new 3025C signal generator features an increased RF output power range of -120 dBm to +7 dBm. "The performance of our signal generator is essentially equivalent to a bench top signal generator, but in a PXI format," said Tim Carey, PXI Product Manager, Aeroflex Test Solutions. "There is no reason to sacrifice phase noise or spurious performance because of the form factor." The signal generators demonstrate phase noise of -125 dBc/Hz at 20kHz offset with a noise floor below -140 dBc/Hz. This signal generator also offers an impressive frequency settling time of 25 us to within 0.7ppm below 85MHz (making it well suited for military hopping radios) and 250 us to within 0.7ppm above 85MHz.

For the digitizers, dynamic range is of primary importance. The modules demonstrate -75dBc spurious free dynamic range (SFDR) and -68dBc adjacent channel leakage ratio (ACLR). Another important spec for signal generators is how well they preserve the signal in phase and amplitude during processing. Amplitude flatness is specified at +/-0.25 dB over a 67-MHz bandwidth. This means, for instance, that the equipment can capture the entire WiMAX spectral mask signal in a single acquisition without distorting the signal in the process of measuring it.

The new modules are available with a lightweight (5.9kg) 8-slot chassis that handles Aeroflex PXI and third-party PXI modules. An optional version of the chassis includes an integrated touch-panel. Designers can order the modules and configure their own chassis, or they can have it preconfigured by Aeroflex as an out of the box solution. In order to address benchtop applications, the company aimed for ISO7779 compliant silent operation of the chassis across the entire operating temperature range.

The company has also released its PXI Studio software application for use with the 3000 Series PXI modules. Available measurement plug-ins enable analysis of WiMAX OFDMA signals as well as general purpose spectrum analysis. Measurement results can be displayed graphically, including EVM spectrum, EVM time, constellation, spectral mask, spectral flatness and burst power. Numerical data is displayed for power, RCE, carrier frequency error, carrier leakage and symbol clock error.
These latest additions to the Aeroflex 3000 Series modular RF test platform are available for delivery beginning in October 2007. Pricing for the complete system comprising signal generation and signal analysis starts at around U.S. $40,000 for 3 GHz and U.S. $50,000 for 6 GHz configurations. Pricing for specific test configurations can be obtained by contacting Aeroflex directly at (800) 835-2352.
