National Instruments PCIe-7841 Multifunction Reconfigurable I/O Device

The PCIe-7841 is a Multifunction Reconfigurable I/O Device manufactured by NI. The part number of the NI PCIe-7841 is 781100-01. This device supports individual channel triggering and sampling at different rates. This model can be used to control signals. The PCIe-7841 has an onboard FPGA. The FPGA type is Virtex-5 LX30. The FPGA controls signal processing and provides flexible timing and synchronization for the system. Independent timing and triggering are also supported by the PCIe 7841. A dedicated ADC is incorporated for this purpose.

The NI PCIe-7841 Multifunction Reconfigurable I/O Device has eight analog input terminals, which can be used in three different modes: DIFF, RSE, and NRSE. The desired mode is selected through software. These terminals support an input signal in the range of +10 V, can sample data at a maximum rate of 200 kS/s, and have a resolution of 16 bits. The input terminals have the impedance of 10 GΩ. It is equipped with 3 68-pin female high-density VHDCI I/O connectors.

The PCIe-7841 also features eight single-ended analog output terminals. These terminals have a maximum update rate of 1 MS/s. The impedance of the output channels of this device is 0.5 Ω. The analog terminals are DC-coupled and have a resolution of 16 bits. The PCIe 7841 offers overvoltage protection for the analog terminals; they can sustain up to +42V. The output terminal’s protection is the short circuit to ground.  

The NI PCIe-7841 Multifunction Reconfigurable I/O Device comes with 96 digital I/O terminals, and 3 DMA channels. These digital terminals are TTL compatible. The digital terminals of the device support two logic levels: 3.3 V and 5V. The output current of the digital terminals is 4.0 mA. The digital terminals can sustain an overvoltage of +20 V without getting damaged.

The NI device weighs 0.28 lb, and measures 6.7 x 4.3 in. in physical dimensions. It has a recommended operating temperature range of 0 °C to 40 °C, a storage temperature range of –20 °C to 70 °C, and a non-condensing operating and storage humidity range of 10% to 90% and 5% to 95% respectively.

The PCIe-7841 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the PCIe-7841 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the PCIe-7841 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped. Call or email us today for more information about calibrating the PCIe-7841!

National Instruments PCIe-7841 Frequently Asked Questions

 

Question: Is it possible to use a PCIe-7841 with NI-DAQmx for analog input and output?

 

Answer: The PCIe-7841 does not work with NI- DAQmx, it requires a LabVIEW FPGA.

 

Question: What is the clock rate of the PCIe-7841?

 

Answer: The clock rate of the PCIe-7841 is 40MHz.

 

Question: How do I output a voltage via one of the analog outputs for the NI PCIe-7841?

 

Answer: To output a voltage via the analog output for the NI PCIe-7841, do a LabVIEW to FPGA interface using C interface to LabVIEW FPGA. Once you deploy your code to FPGA and write your C code and then create a .dll out of your C code.
