National Instruments PXI-7830R PXI Multifunction Reconfigurable I/O Module

The PXI-7830R (Part number: 779364-01) Multifunction Reconfigurable I/O Module has four 16-bit analog input channels, four 16-bit analog output channels, 56 bidirectional DIO lines that the user can arrange exclusively for input or output, and a Virtex-II 1M gates FPGA. This module has 200 kS/s maximum sampling rate and 1 MS/s maximum update rate.

To estimate a grounded signal source with a single-ended input mode, the user should arrange the NI PXI 7830R in the NRSE input mode. Then, associate the signal to the positive input of the PXI-7830R instrumentation enhancer and interface the nearby signal ground reference to the negative input of the instrumentation intensifier. The ground purpose of the signal ought to be associated with AISENSE. Any potential distinction between the NI PXI 7830R ground and the signal ground shows up as a typical mode motion at both the positive and negative inputs of the instrumentation enhancer. The instrumentation enhancer rejects this distinction. If the information hardware of the National Instruments PXI-7830R is referenced to ground in RSE input mode, this distinction in ground possibilities shows up as a mistake in the measured voltage.

This Multifunction RIO Module offers an Analog Output function, where the bipolar output range of the NI PXI-7830R AO channels is settled at ± 10 V. A few applications require that the AO channels control on to known voltage levels. To set the power-on levels, the user can configure the PXI-7830R to load and run to VI when the system power is on. The VI can set the AO channels to the desired voltage levels. The VI deciphers information written to the DAC in two's complement format.

The PXI-7830R is run using the NI-RIO driver software which is compatible with software packages such as LabVIEW FPGA Module and LabVIEW Real-Time Module. The NI device weighs 152 g, and measures 6.3 x 3.9 in. in physical dimensions. It has a recommended operating and storage temperature range of 0 °C to 55 °C and –20 °C to 70 °C respectively.

PXI-7830R Obsolete Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
