MIMO-ready test solution for wideband wireless devices
The PXI 3050A low noise RF signal generator and the PXI 3320 arbitrary waveform generator (AWG) are used together to provide a fully configurable RF signal generator with wide bandwidth vector modulation, low phase noise, and fast frequency and level settling. The signal generator is available in two frequency range options–from 100 kHz to either 3 GHz or 6 GHz –and with a choice of +10 dBm or +20 dBm output power. A 200 MHz modulated RF bandwidth with low residual error vector magnitude (EVM) of less than 0.5% makes it the ideal choice for wideband standards using high order 256 QAM modulation, such as 802.11ac. Excellent linearity (ACLR) of greater than 70 dB 3GPP TM1 makes 3050A ideal for use in test solutions for power amplifiers and repeaters.
Phase noise is best-in-class at -135 dBc/Hz at 1 GHz with 20 kHz offset while maintaining excellent frequency agility with settling times of less than 100 µs.
The PXI 3070A is a high performance RF digitizer with up to 160 MHz of instantaneous IF bandwidth for analyzing wide bandwidth signals. The 3070A is available in two frequency range options from 250 MHz to either 3 GHz or 6 GHz, with test suites for general purpose spectrum analysis and support for the latest standards including WLAN 802.11a, b, g, n, ac and MIMO. This wide instantaneous IF bandwidth allows true measurement of 160 MHz wide OFDMA signals without the stitching required by other products, and so avoids ambiguities in carrier leakage and spectral flatness measurements. Measurement speed is also improved.
