LIG Nex1 Spectrum Analyzer Features Xilinx VII-1000 FPGA
RF Engines Limited (RFEL) have completed their latest design for LIG Nex1's latest spectrum analyzer instrument. RFEL have been working with LIG Nex1 of Korea for a number of years, and have most recently supplied an advanced SpectraChip IF design that is a digital replacement for the analog intermediate frequency (IF) filtering section of LIG Nex1's latest instrument.
This latest design incorporates additional decimation functions, a new digital modulation analysis core, incorporates a memory selection function of either SDRAM or FIFO for data capture, additional time domain triggering capability, and an increase in the bandwidth of the initial down conversion function from 20MHz to 30 MHz. The board design has been developed in house by LIG Nex1, and is based on the Xilinx VII-1000 FPGA.
Replacing traditional analog components with modern digital techniques helps to make the systems easier to manufacture, more reproducible and more reliable. The use of digital technology also saves on the manufacturing alignment costs normally associated with analogue circuitry, and the guaranteed repeatability of the digital design reduces both the need for, and the costs, of ongoing calibration.
