The National Instruments NI-5793 is a high-performance RF Adapter Module designed for the FlexRIO system, offering an extensive operating frequency range from 200 MHz to 4.4 GHz with a maximum instantaneous bandwidth of 200 MHz. Engineered for precision, this module boasts a receiver dynamic range exceeding 105 dB and a noise figure of less than 8 dB at 2 GHz, ensuring optimal signal fidelity. It also features impressive local oscillator (LO) phase noise levels below 94 dBc/Hz at 2.4 GHz with a 10 kHz offset, enabling highly accurate measurements. The NI-5793 achieves a loopback error vector magnitude (EVM) of under 1.5 percent, making it suitable for advanced RF applications.

Incorporating twelve bidirectional digitally controlled I/O lines, the module facilitates sophisticated device under test (DUT) control and offers seamless advanced protocol integration. The NI-5793, in conjunction with the PXI platform, supports AD and DA synchronization essential for channel extension, alleviating issues related to trigger propagation delays across devices by utilizing a Common Pulse Timing Reference (CPTR) for precise timing alignment. When configured properly, all devices connected to the NI-5793 can synchronize on the same FPGA I/O line, ensuring that clock edges are detected simultaneously across multiple FPGAs.

Measuring 5.1 x 0.8 x 4.7 inches and weighing 14.6 ounces, the NI-5793 is compact yet powerful and is covered by a comprehensive 2-3 year warranty. User and maintenance manuals are available for download to assist users in maximizing the module's capabilities.
