National Instruments PCIe-7841R Multifunction Reconfigurable I/O Device

The PCIe-7841R (Part number: 781100-01) is a Multifunction Reconfigurable I/O Device from National Instruments. The instrument integrates the advanced FPGA technology. It allows the users to reconfigure its various parameters. The FPGA type is a Virtex-5 LX30. The instrument comes with the integrated processing capability for different tasks, which includes controlling signals at the input or output side of the NI PCIe-7841R. The sample rate has the value of 200 kS/s.

The NI PCIe-7841R Multifunction Reconfigurable I/O Device also comes with clock generation. This device can generate the clock at the frequency of 40 MHz. The device comes with 96 bi-directional channels. These channels are digital. The instrument also integrates an ADC, which is provided for each channel separately.  This feature enables the device to complete measurements that involve trigger and timing schemes. The NI PCIe-7841R offers different modes to input the data. The user can select these modes with the help of software. These modes include DIFF, RSE, and NRSE modes of operation. The instrument additionally implements various protection schemes, which aid in protecting the device from damage during overcurrent and overvoltage conditions.

The NI PCIe-7841R device has a conversion time of four micro-seconds. It enables to accomplish measurements and analysis more quickly. The update time of the output side of the device is one micro-second. The maximum update rate of it is one MS per second. The value of the slew rate offered by the instrument is 10 volts per micro-seconds.
