National Instruments 781260-01

The National Instruments 781260-01 is a PXIe-5673E PXI Vector Signal Generator designed for applications requiring high-performance signal generation and analysis. This model features a single input channel and comes equipped with 64 MB of memory, facilitating efficient operation and signal processing. The 781260-01 integrates three distinct modules, including the PXIe-5601 RF Signal Downconverter, the PXIe-5622 PXI IF Digitizer (specifically part number 780412-01), and the PXIe-5652 Local Oscillator Source Module, which distinguishes it from other configurations of the same model.

For users requiring increased memory capacity, the alternative part number 781260-02 offers the same core specifications but includes the PXIe-5622 Digitizer with 256 MB of memory. This variation supports a broader array of applications due to its enhanced storage capability. Effective operation of the 781260-01 necessitates an MXI controller or PXIe embedded controller, along with a compatible PXIe chassis to house the modules securely. Careful adherence to safety precautions is advised during setup to mitigate the risk of damage.

The front panel of the 781260-01 features six LED indicators—two for each module—that provide critical operational feedback. The ACCESS indicators signal the state of module access, with colors indicating functional status or potential issues. The ACTIVE LEDs inform users of the overall generation activity; if off, signaling that waveform generation has ceased, while green indicates active generation and red alerts to errors.

This unit operates within an ambient temperature range of 0 °C to 55 °C and is eligible for free ground shipping. The National Instruments 781260-01 is a robust solution for precision signal generation and analysis in complex industrial environments.
