RF vector signal generator employs quadrature digital upconversion

摘要

National Instruments' PXIe-5672 is a compact, three-slot 3U vector signal generator module that uses superheterodyne or IF upconversion to RF signals. To achieve that, it combines two existing modules into one PXI Express instrument: a PXIe-5442 arbitrary waveform generator and a PXI-5610 upconverter. Released recently at NIWeek, the PXIe-5442 is a 100 Msps arbitrary waveform generator with onboard signal processing (OSP). OSP functions include pulse shaping and interpolation filters, gain and offset control, a numerically controlled oscillator (NCO), and IQ mixing for quadrature digital upconversion.
