The ZT8450 I/Q Digitizer is optimized for I/Q demodulator RFIC testing supporting OFDM waveforms including 802.11 a/n/ac Wi-Fi, WiMAX, and LTE. It functions as a baseband vector signal analyzer from DC to 300 MHz, providing the signal fidelity and real-time processing capabilities for performing EVM, ACLR, and IM3 measurements or addressing complex MIMO applications.
Key specifications of the ZT8450 include I/Q or dual IF differential inputs, two 14-bit 400 MS/s ADCs, 512-MB deep memory, 300-MHz analog bandwidth, and on-board DDC with fractional resampling. I/Q input gain of 0 dB to 30 dB and unaliased DDC instantaneous bandwidth up to 160 MHz are programmable. The digitizers are available in two or four channels in PXI, PCI, VXI, and LXI configurations.
