National Instruments 782377-01 RF and Baseband Vector Signal Transceiver

The National Instruments 782377-01 (PXIe‑5645R) RF and Baseband Vector Signal Transceiver (VST) is a highly integrated device that combines a vector signal generator and a vector signal analyzer with FPGA based real time signal processing capabilities. The model operates within a frequency range of 65 MHz to 6 GHz. The module provides an 80 MHz bandwidth that ensures precise signal analysis and generation across a broad spectrum.

This Vector Signal Transceiver features a high performance differential or single-ended baseband I/Q interface. The model delivers accurate frequency control with a tuning resolution of less than 1 Hz and programmable LO step sizes in fractional and integer modes. The device also boasts fast frequency settling times along with a maximum time of 1.2 ms for settling within 0.1 × 10⁻⁶ of the final frequency that ensures minimal downtime during frequency transitions.

In addition, the model’s spectral features phase noise levels as low as -99 dBc/Hz at a 20 kHz offset for frequencies under 3 GHz. This low phase noise is essential for maintaining signal integrity in demanding RF environments. The RF input stage supports an amplitude range from the noise floor to +30 dBm along with an amplitude settling time of 125 μs to achieve 0.1 dB of the final value. This level of precision is vital for applications requiring accurate signal measurement and analysis.

The NI 782377-01 FPGA (Xilinx Virtex-6 LX195T) is equipped with 124,800 LUTs and 249,600 flip-flops that provides substantial processing power for real time signal manipulation. This enables the execution of complex algorithms directly on the device. The onboard DRAM and SRAM facilitate high speed data transfers and efficient memory management ALONG with a theoretical maximum data rate of 2.1 GB/s per DRAM bank. Its I/Q input and output channels offer a complex equalized bandwidth of 80 MHz. The device also supports a comprehensive range of environmental conditions with an operating temperature range from 0 °C to 55 °C and the ability to withstand high levels of shock and vibration. The model weighs 1758 g and has physical dimensions of 8.1 cm × 12.9 cm × 21.1 cm (3.2 in × 5.6 in × 8.3 in).
