National Instruments 781260-01 PXI Vector Signal Generator

The 781260-01 from National Instruments is the descriptive part number for the variation of the PXIe-5673E PXI Vector Signal Generator that includes 1 input channel and 64 MB of memory. While this part number represents only one model name, the model itself is comprised of three individual NI modules that are connected together. This specific variation of the device stands out from the other part numbers for the model because it uses the PXIe-5652 Local Oscillator Source Module. The other two modules that make up the 781260-01 are the PXIe-5601 RF Signal Downconverter and the PXIe-5622 PXI IF Digitizer (specifically part number 780412-01 of this device). 

While the 781260-01 has 64 MB of memory, even more space can be found with a different variation of the signal generator. Part number 781260-02 shares almost all of the same specifications as the 781260-01. The only difference is that the 781260-01 uses a PXIe-5622 Digitizer with 256 MB of memory, allowing much more space for a variety of applications. This increase in memory is found specifically by using the version of the PXI IF Digitizer that is identified as part number 780412-02.

An MXI controller (or a PXIe embedded controller), along with a PXIe chassis to contain the various modules, are both necessary hardware for operating the 781260-01 effectively. When setting up direct links to the modules, the user should carefully adhere to relevant safety precautions in order to prevent any potential damages. 

Once fully assembled, the front panel of the 781260-01 has 6 LED indicators. These LEDs, divided as two per module, offer insight into the ACTIVE and ACCESS statuses of the individual components for the device. ACCESS refers to the state of the basic hardware of the module. When this LED is off, it means that the device is either not functional or has an error with the power. An amber color means that the device is currently being accessed, while a green color indicates that the device is ready to be programmed. The ACTIVE LED indicates the overall status of the modules. When the LED is off, it means that the generation of the 781260-01 has stopped. A green color means that the module is currently generating a waveform, while a red color indicates an error.
