NI-MCal calibration technology for improved measurement accuracy

OverviewNI M Series high-accuracy multifunction data acquisition (DAQ) devices are optimized for 18-bit analog input accuracy. This resolution is equivalent to 5 digits for DC measurements. To ensure accuracy, the NI-PGIA 2 amplifier technology is optimized for low noise and fast settling to 18 bits, and the onboard lowpass filter rejects high-frequency noise and prevents aliasing. M Series devices are ideal for applications including test, control, and design. All high-accuracy devices have a minimum of 16 analog inputs, 24 digital I/O lines, seven programmable input ranges, analog and digital triggering, and two counter/timers. They also have an extended two-year calibration interval.Requirements and Compatibility

Application and Technology

M Series for Test

For test, you can use M Series high-accuracy analog inputs and 10 MHz digital lines with NI signal conditioning for applications including electronics test, component characterization, and sensor and signal measurements requiring instrument-class accuracy. The 18-bit analog-to-digital converter (ADC) and available filtering provide a 4 times increase in resolution and 5 times more measurement sensitivity. With fast sampling rates and a low noise floor, these devices can accurately acquire dynamic signals. For better noise rejection, the onboard lowpass filters significantly improve device accuracy. Advanced analog clamping circuitry protects the hardware from overvoltage conditions and ensures accurate measurements on nonsaturated channels. High-accuracy M Series devices are compatible with NI SCC and SCXI signal conditioning platforms, which provide amplification, filtering, and power for virtually every type of sensor. These platforms also are compliant with IEEE 1451.4 smart transducer electronic data sheet (TEDS) sensors, which offer digital storage for sensor data sheet information.

M Series for Control

M Series digital lines can drive 24 mA for relay and actuator control. By clocking the digital lines as fast as 10 MHz, you can use these lines for pulse-width modulation (PWM) to control valves, motors, fans, lamps, and pumps. With four waveform analog outputs, two 80 MHz counter/timers, and six DMA channels, M Series devices can execute multiple control loops simultaneously. The analog outputs on the high-accuracy M Series devices can generate up to 2.86 MS/s and provide user-defined programmable offsets and ranges for maximum waveform resolution over any custom range. High-accuracy M Series devices also have direct support for encoder measurements, protected digital lines, and digital debounce filters for control applications. With up to 32 analog inputs, 32 clocked digital lines, and four analog outputs, you can execute multiple control loops with a single device. For higher-count control loops, you can use M Series devices in conjunction and tightly synchronized with National Instruments analog output devices for 64 or more loops. With the NI SoftMotion Development Module for LabVIEW, you can create a complete custom motion controller with M Series devices.

M Series for Design

For design applications, you can use the wide range of I/O - from 32 analog inputs to 48 digital lines - to measure and verify prototype designs. M Series devices and NI LabVIEW SignalExpress interactive measurement software deliver benchtop measurements to the PC. With LabVIEW SignalExpress interactive configuration-based steps, you can quickly create design verification tests. The fast acquisition and generation rates of high-speed M Series devices along with LabVIEW SignalExpress provide on-the-fly design analysis. You can convert your tested and verified LabVIEW SignalExpress projects to LabVIEW applications for immediate M Series DAQ use and bridge the gap between test, control, and design applications.

Hybrid-Slot-Compatible PXI Modules

M Series modules for PXI are hybrid-slot-compatible so that you can use them in both PXI slots and the hybrid slots found in new PXI Express chassis. The PXI Systems Alliance specifies that hybrid-slot-compatible PXI modules use modified slot connectors to mechanically fit in both PXI slots and hybrid slots. This mechanical change:

Provides compatibility with past, current, and future PXI chassis

Maintains existing product specifications

Requires no software changes (application or driver)

Maintains speed and capability of all PXI communication (PXI Express signaling is not provided).However, hybrid-slot-compatible PXI modules do not include the pins used to implement PXI local bus communication, which is used for backplane SCXI control from the right-most PXI slot in PXI/SCXI combination chassis (NIPXI-1010, PXI-1011, PXI-1050, and PXI-1052). For these applications, NI provides unmodified M Series PXImodules that maintain the required local bus capabilities. Refer to the SCXI Control of PXI/SCXI Combination Chassis section in the Ordering Information section for part numbers.

Simultaneous and Intelligent Data Acquisition

When you need to obtain performance from a data acquisition device beyond the capabilities of a multifunction DAQ device, National Instruments provides simultaneous sampling with the S Series and intelligent DAQ with the R Series. The S Series architecture dedicates an ADC per channel to provide higher aggregate sampling rates compared to multiplexed devices. S Series devices are ideal for applications including IF digitization, transient recording, ultrasound and sonar testing, and high-energy physics.

R Series multifunction DAQ devices contain a 1M/3M gate field-programmable gate array (FPGA) that is reconfigurable using the NILabVIEW FPGA Module. These devices have up to eight independent 16-bit analog inputs with up to 200 kHz simultaneous sampling, up to eight independent 16-bit analog outputs with up to 1 MHz simultaneous update rates, and up to 96 digital I/O lines configurable at rates up to 40 MHz. You can customize these devices to develop capabilities such as complete control over the synchronization and timing of all signals and operations; user-defined onboard decision-making logic; and digital lines individually configurable as input, output, counter/timers, PWM, flexible encoder inputs, or user-defined communication protocols.

Signal Conditioning

Signal conditioning is required for sensor measurements or voltage inputs greater than 10 V. NI SCXI is a versatile, high-performance signal conditioning platform, optimized for high-channel-count applications. NI SCC provides portable, flexible signal conditioning options on a per-channel basis. Visit ni.com/sigcon for resources on available NI signal conditioning.

Quad-Core Processor

The NIPXIe-8135 includes the quad-core Intel Core i7-3610QE processor. Quad-core processors contain four cores, or computing engines, in one physical package. To increase the number of threads that you can process, the NIPXIe-8135 incorporates Intel Hyper-Threading technology that takes each of the four physical cores and splits them into two virtual cores, for a total of eight virtual cores. These eight virtual cores can execute eight computing tasks, which is advantageous in multitasking environments such as Windows 7. Multithreaded system development environments, such as NI LabVIEW, can take full advantage of the processing cores on the NIPXIe-8135 by automatically separating their tasks into independent threads.

High Bandwidth

This controller features the Intel Corei7-3610QE processor and takes advantage of advancements in PCI Express technology. This processor provides four x4 (by four) PCI Express Gen 2 lanes to the PXI chassis backplane. This generates up to 2 GB/s of dedicated slot bandwidth with the overall system bandwidth of up to 8 GB/s. Pairing the NIPXIe-8135 with a PXI Express chassis, such as the NIPXIe-1085, you can simultaneously stream a larger set of I/O channels to the controllers system RAM, allowing for the creation of larger and more complex data record and playback applications. For example, by using an NI PXIe-1085 PXI Express chassis and an NI PXIe-8135 embedded controller, you can stream data from 32 input channels with 16-bit resolution sampled at 100 MS/s into system memory for analysis or postprocessing.

Hardware

With state-of-the-art packaging, the NIPXIe-8135 integrates the Intel Core i7-3610QE processor and all standard and extended PC I/O ports into a single unit. Because many of the I/O ports on the controller are integrated, all active slots in the chassis remain available for measurement and control modules. This rugged controller design minimizes integration issues and eliminates the need for complex cabling to daughter boards.

NI PXIe-8135 Block DiagramPeripheral I/O

This module includes high-performance peripheral I/O such as two 10/100/1000BASE-TX (Gigabit) Ethernet ports, two SuperSpeed USB ports, and four Hi-Speed USB ports for connection to a keyboard, mouse, CD-ROM/DVD-ROM drive for software installation, or other standard PC peripherals such as speakers, printers, or memory sticks. Use the IEEE 1284 ECP/EPP parallel port to connect to a wide variety of devices, including tape backup drives and printers. An RS232 port is available for connecting to serial devices. Additionally, the NIPXIe-8135 controller includes an integrated GPIB (IEEE 488) controller, which provides control of external instrumentation, saving additional cost and a slot.

Video

The NI PXIe-8135 includes an integrated ATI Radeon E4690 graphics processing unit, which delivers intense, realistic 3D graphics with sharp images, fast rendering, smooth motion, and high detail, without the need for an additional video card or peripheral. This unique architecture provides balanced memory usage between graphics and the system for optimal performance. Additionally, the NIPXIe-8135 features two Display Port video connectors. A Display Port to VGA adapter is included with the controller for use with VGA monitors. For information on approved Display Port to DVI adapters, reference this KnowledgeBase.

Dual Monitor Support

The dual Display Port video ports on the NIPXIe-8135 support simultaneous output. With this built-in capability, you can connect two monitors to your PXI system at the same time with independent displays. This negates the need for a separate PXI or CompactPCI video module to connect two monitors to your PXI system.

Memory

The NIPXIe-8135 uses dual-channel 1600 MHz DDR3 SDRAM, which makes the controller ideal for data-intensive applications requiring significant analysis. It has two SO-DIMM sockets for the DDR3 SDRAM. 8 GB (2 x 4 GB DIMM) of RAM is standard with upgrade options to 16 GB.

Extended Temperature and 24/7 Operation Option

You can choose from two versions of the NI PXIe-8135 embedded controller to address different environmental and usage conditions. The primary difference between the versions is that the version for extended temperature and 24/7 operation uses a different hard drive that is designed for both reliability in low- and high-temperature extremes and 24/7 operation. The standard version of the controllers has an operating temperature of 5 to 50 C and a storage temperature of -40 to 65 C. The extended temperature and 24/7 operation version has an operating temperature of 0 to 55 C and a storage temperature of -40 to 70 C.

You can also use the extended temperature and 24/7 operation version for applications that require continuous operation for up to 24 hours/day, seven days/week because the hard drive is rated for 24/7 operation. The hard drive in the standard version of the controllers is designed to be powered on for eight hours/day, five days/week. Additionally, 24/7 operation applications may subject the hard drive to a high-duty cycle (the percentage of the maximum sustained throughput of the hard drive). The hard drive in the extended temperature and 24/7 operation version has a capacity of 80 GB (minimum). See specifications for further details.

USB Peripherals

National Instruments offers a USB-to-dual-PS/2 keyboard/mouse adapter cable to connect a legacy PS/2 keyboard and mouse to a single USB port on your embedded controller. Additionally, NI offers external USB CD-ROM/DVD-ROM and USB floppy drives for use with your embedded controller. Connect these drives to your embedded controller for easy software installation and upgrades. Both are completely powered through the USB ports, so no external power connections are required. Additional USB peripherals, such as USB speakers to add audio or USB memory sticks to add easily removable memory, are widely available from PC peripheral manufacturers.

In-ROM Memory and Hard-Drive Diagnostics

To improve the serviceability of the NI PXIe-8135, in-ROM diagnostics for the hard drive and memory can be quickly accessed without requiring external third-party tools. By running these diagnostics, the results of analysis can determine if replacement of the hard drive or memory is required. The design of the controller allows for quick field replacement of critical components such as the hard drive and the memory without affecting the warranty. To ease the process of buying spare components, you can purchase hard drive and memory upgrades with the NI PXIe-8135. The combination of this and the in-ROM diagnostics significantly improves NI PXIe-8135 serviceability.

Hard-Drive-Based Recovery Image

The NIPXIe-8135 embedded controller is shipped with a factory image of the software installation stored on a separate partition of the hard drive. In the case of software corruption, you can invoke a recovery tool during the controllers boot-up process that can use this backup image to restore the controller to its shipping software configuration. You also can use this recovery tool to create custom images that you can store on external mass storage devices such as a USB memory stick, USB hard drives, and USB CD/DVD drives. With this ability, you can create custom backup images that you can use to either recover an NIPXIe-8135 controller or replicate the installation on other NIPXIe-8135 controllers. For more information on this tool, refer to KnowledgeBase 2ZKC02OK.
