National Instruments 779670-02

The National Instruments 779670-02, also designated as the PXI-5652, is a high-performance PXI RF Analog Signal Generator, specifically engineered for comprehensive RF application support. This device operates over an extensive frequency range of 500 kHz to 6.6 GHz and provides exceptional frequency resolution with less than 3 Hz resolution for frequencies up to 1.3 GHz, and progressively less resolution for higher frequencies. It features impressive median frequency settling times of 1.0 ms in wide loop bandwidth mode, achieving a remarkable precision of 0.01 ppm. The internal reference clock offers a maximum initial accuracy of ±3 ppm and exceptional stability, with a maximum temperature variation of ±1 ppm. The module supports multiple synchronization options, including both internal and external reference inputs at 10 MHz.

The NI 779670-02 excels in spectral purity, showcasing single sideband phase noise as low as -125 dBc/Hz at a 10 kHz offset from 100 MHz and residual FM values typically under 0.8 Hz RMS at 1 GHz. In terms of jitter performance, the device maintains an RMS jitter of less than 200 femtoseconds at 622 MHz across a bandwidth of 1 kHz to 5 MHz. Its modulation capabilities include frequency modulation (FM) supporting sine, triangle, and square waveforms with maximum deviations reaching 8 MHz, as well as frequency shift keying (FSK) accommodating various modulation waveform types including PRBS and user-defined options, with maximum deviations of 2 MHz at frequencies up to 6.6 GHz.

Designed for operation in challenging environments, the 779670-02 functions reliably within a temperature range of 0°C to 55°C and is rugged enough to withstand non-operational shocks of up to 30 g peak and random vibrations. It adheres to several safety standards, including IEC 61010-1 and UL 61010-1. The compact 3U PXI form factor, combined with a weight of 415 grams, facilitates straightforward installation and offers a robust solution for advanced RF signal generation needs.
