Innovative Integration released the latest model in their family of digital transceivers, turnkey and commercial off-the-shelf solutions that integrate data logging, digital down-conversion (DDC), digital up-conversion (DUC) and spectrum analysis (FFT) in a compact system. The K706 digital transceiver has two antenna inputs and four independent channels of DDC, two channels of DUC and one spectrum analyzer embedded in a Xilinx Kintex-7 FPGA. It supports monitoring and recording of wideband or narrowband spectra or channelized IF band data. The system runs on a 64-bit Linux or Windows application. A touch screen is available, which is useful for custom wireless surveillance or SDR receiver instrumentation.
The analog front-end is modularized via an FMC site which, fitted with an FMC-1000, employs dual, 1 GHz, 14-bit ADCs and DACs. The product supports contiguous recording at 160 MBps to internal 1.8" SATA drives. Each DDC has its own programmable tuner, programmable lowpass filtering, gain control and decimation settings that support output bandwidth to 100 MHz. Data is packetized in the VITA-49 format, with accurate timestamps synchronous to an external PPS signal. Each DDC channel can be enabled and disabled on the fly, to conserve host computer storage and bandwidth. An embedded power meter monitors the input power to the ADCs, which allows analog gain control using optional, user supplied and external front-end devices.
The spectrum analyzer, which supports windowing, calculates the wideband spectrum of raw ADC data or the narrowband spectrum of the DDC output data at a programmable update rate. A programmable peak hold feature may be enabled to latch transient activity in the spectrum. The programmable threshold monitoring spectrum feature tracks spectral activities to 512 bins.
