Software measurement suite from NI for Mobile WiMAX devices automated testing

National Instruments has introduced a software measurement suite that uses modular RF instrumentation for automated testing of Mobile WiMAX devices, which reduce test time by up to 300 percent with better accuracy and high flexibility.

The suite provides enhanced flexibility with the same equipment used for testing Mobile WiMAX devices to test hardware that complies with other standards such as Fixed WiMAX, wireless local area network (WLAN), GPS, and GSM/EDGE/WCDMA cellular standards.

The measurement suite is based on PXI Express instrumentation powered by multicore technology, and features error vector magnitude (EVM), power and spectral measurements three to five times faster than traditional instruments.

With a typical residual EVM accuracy of -46 dB at 3.5 GHz (-10 dBm), this test system can perform high accurate measurements than alternative production test-grade instruments.

The Measurement Suite for Mobile WiMAX supports channel bandwidths from 1.25 to 28 MHz and fast Fourier transform (FFT) sizes 128, 256, 1024 and 2048, and all Mobile WiMAX modulation types with both convolution coding and turbo convolution coding. The Measurement Suite for Mobile WiMAX also can generate or analyze signals with up to eight zones and 16 bursts. Combined with the NI PXIe-5663E RF vector signal analyzer and NI PXIe-5673 RF vector signal generator, the measurement suite also provides continuous frequency coverage from 85 MHz to 6.6 GHz.

"The NI Measurement Suite for Mobile WiMAX reflects the continued investment from National Instruments to provide test solutions for engineers developing next-generation wireless technology devices," said Eric Starkloff, vice president of test marketing at National Instruments. "With this new solution, we now can provide engineers the ability to significantly reduce their test cost by providing R&D-grade instrumentation that performs measurements three to five times faster than traditional solutions."

The Measurement Suite for Mobile WiMAX supports multiple PXI hardware configurations to meet different application needs.
