National Instruments 784777-01

The National Instruments 784777-01 RF Analog Signal Generator is a high-performance device designed for advanced testing applications. Part of the PXIe-5654 series, this generator delivers a frequency range of up to 20 GHz and features extended amplitude capabilities when paired with the NI PXIe-5696 Amplitude Extender, achieving an amplitude range of up to 27 dBm. The unit excels in phase noise performance and offers quick frequency tuning with a resolution of 0.001 Hz, making it suitable for a broad array of signal generation tasks. For enhanced efficiency, the optional fast tuning capability available in model 784777-02 enables transitions to any frequency below 250 MHz in just 100 microseconds, significantly improving measurement responsiveness compared to the standard settling time of 1 ms.

Power requirements for the 784777-01 vary based on the rail used, with a typical current draw of 1.9 A at +3.3 V and 2.4 A at +12 V. The generator is designed to operate within an environmental temperature range of 0 °C to 55 °C and can withstand storage temperatures from -40 °C to 71 °C. Humidity levels should be maintained at 10% to 90% (noncondensing) during operation, while storage requires a range of 5% to 95% humidity (noncondensing). This module occupies three PXIe slots, measuring 6.1 cm x 13.0 cm x 21.4 cm (2.4 in. x 5.1 in. x 8.4 in.) and has a weight of 1,328 g (46.8 oz). The 784777-01 comes with a three-year warranty, ensuring reliability for demanding applications.
