The PT-325 is an RF tuner card designed to be installed with the Ettus Research™ Universal Software Radio Peripheral (USRP™) N200 series chassis. The PT-325 allows UHD and GNU Radio users to experience the benefits of a high-performance RF tuner architecture that represents a major improvement over low-end, direct conversion tuners. The PT-325 is ideal for moving software-defined radio applications from laboratory settings to real-world signal environments.
The PT-325 tunes from 23 to 3000 MHz with high linearity and excellent preselection for performance in harsh RF environments. It features a traditional superheterodyne architecture that outputs digitized IF data to the USRP’s motherboard FPGA, where it can be down-converted and decimated to produce baseband I/Q data at a rate and format compatible with UHD and GNU Radio.
