National Instruments 784777-01 RF Analog Signal Generator

Part number 784777-01 from National Instruments is the descriptive part number for the version of the PXIe-5654 RF Analog Signal Generator that boasts 20 GHz of frequency and features extended amplitude capabilities. When paired with the NI PXIe-5696 Amplitude Extender, the amplitude range of the 784777-01 reaches up to 27 dBm. This versatile generator offers superior phase noise and frequency tuning time, in addition to intermodulation distortion tests boasting high performance. With a resolution of 0.001 Hz, this generator is an excellent choice for a wide range of testing applications.

Fast tuning is another option available for this analog signal generator, represented by the part number 784777-02. Fast tuning allows the device to quickly tune both to and from any frequency under 250 MHz in 100 µs. Without this feature, the standard settling time for the device is 1 ms. The tuning capability of the 784777-02 improves the responsiveness of the system and the efficiency of the measurements.

The power requirements of the 784777-01 depend on the power rail used. A voltage of +3.3 draws in a typical current of 1.9 A and a maximum current of 2.5 A. For a voltage of +12 V, the typical current draw is 2.4 A while the maximum is 3 A.

The 784777-01 is designed for use in a variety of environmental settings. It should only be operated in temperatures ranging from 0 °C to 55 °C. When in storage, the generator can tolerate an even wider range of temperatures, spanning from -40 °C to 71 °C. The relative humidity range of the environment where the 784777-01 is being used should stay within a range of 10% to 90% (noncondensing), while the humidity can range between 5% to 95% for storage conditions (also noncondensing). Designed with a 3 slot PXIe module size, the 784777-01 has dimensions of 6.1 cm x 13.0 cm x 21.4 cm (2.4 in. x 5.1 in. x 8.4 in.) and weighs in at 1,328 g (46.8 oz).
