National Instruments 781262-01 PXI Vector Signal Generator

Part number 781262-01 from National Instruments is the identifying number for the version of the PXIe-5673E PXI Vector Signal Generator that has a frequency of 3.3 GHz. This part number describes independent models that are connected together to operate as a signal generator. These National Instruments devices include: the PXIe-5450/5451 Arbitrary Waveform Generator, the PXIe-5611 I/Q Modulator, and the PXIe-5650/5651/5652 Local Oscillator Source Module. The 781262-01 is equipped with 128 MB of RAM, offering plenty of space for a wide variety of testing applications. An additional variation of this part that features an impressive 512 MB of RAM can be found under the part number 781262-02.

When assembled together, the front panel of the 781262-01 features a variety of connectors for optimal functionality. The majority of these connections are SMA Female connector types- there are 8 on the front panel of the I/Q modulator module, 2 on the LO Source Module, and 6 on the AWG module. The arbitrary waveform generator also includes 2 SMB connectors on it’s front panel.

The typical power for the 781262-01 differs depending on the module. The I/Q Modulator has a typical DC power of 10.5 W, while the AWG has a typical power of either 32.7 W (PXIe-5450) or 37.5 W (PXIe-5451). The typical power of the LO Source module is 12.6 W.

Designed for operation in a wide range of environmental conditions, the 781262-01 is capable of operation in altitudes up to 2,000m. The device should only be operated within temperatures ranging from 0 °C to 55 °C, and it weighs in at a total of 1,458 g (52 oz).
