National Instruments PXI-5651

The National Instruments PXI-5651 is a high-performance PXI RF Analog Signal Generator designed to deliver precise signal generation capabilities across a frequency range of 500 kHz to 3.3 GHz. This module features advanced Direct Digital Synthesis (DDS) technology, enabling fine-tuning steps of 1 Hz or less for exceptional signal accuracy. The instrument incorporates automatic leveling control (ALC) that provides stable amplitude control using a temperature-stable digital-to-analog converter (DAC), ensuring performance reliability over a wide frequency response from a few kilohertz up to 3.3 GHz. The PXI-5651 offers -110 dBc/Hz phase noise at a 1 GHz frequency with a 10 kHz offset, and supports various modulation schemes, including frequency modulation (FM), 2-FSK, and on-off keying (OOK). With a maximum output power of 12 dBm, this signal generator is further enhanced by the NI-RFSG instrument driver, which utilizes calibration data stored in EEPROM to optimize signal generation and compensate for nonideal components. Measuring 8.5 x 0.8 x 5.1 inches and weighing 14.6 ounces, the PXI-5651 is a compact solution well-suited for a variety of applications, including testing and simulations in RF communications.
