National Instruments 781340-02 PXI Vector Signal Generator

Part number 781340-02 from National Instruments is the identifying number for the version of the PXIe-5673E PXI Vector Signal Generator that has 512 MB of onboard memory per channel. This part number refers to the collaborative use of individual parts- namely the NI PXIe-5450/5451 AWG Module, the NI PXIe-5611 I/Q Modulator Module, and the NI PXIe-5650/5651/5652 LO Source Module. While the 781340-02 is equipped with 2 channels, the device is also available in variations that feature 3 channels (part number 781340-03) and 4 channels (part number 781340-04).

When paired with the right software, the wide-bandwidth 781340-02 is capable of producing a wide range of signals and waveforms. Boasting stream-to-disk capabilities, the generator has plenty of space to support continuous waveforms. The front panel of the device features a range of SMA female connectors in addition to two SMB connectors- facilitating easy connectivity between the different modules.

The DC power specifications for the 781340-02 differ depending on the module. The I/Q Modulator has a typical power of 10.5 W, while the typical power for the AWG module is either 32.7 W (PXIe-5450) or 37.5 W (PXIe-5451). Lastly, the LO Power Module has a typical power of 12.6 W.

Built to withstand a wide range of environmental factors, the 781340-02 should only be operated within temperatures ranging from 0 °C to 55 °C. When in storage, the device can be securely stored within a wider temperature range spanning from -40 °C to 71 °C. When all devices are connected, the 781340-02 weighs a total of 1,458 g (52 oz). The individual dimensions of the modules that make up the signal generator are 21.6 cm × 2.0 cm × 13.0 cm (8.5 in. × 0.8 in. × 5.1 in.) for a one slot PXIe module, 21.6 cm × 4.0 cm × 13.0 cm (8.5 in. × 1.6 in. × 5.1 in.) for a two slot PXIe module, and 21.6 cm × 2.0 cm × 13.0 cm (8.5 in. × 0.8 in. × 5.1 in.) for a one slot module that is not PXIe.
