Features

The NI hig h-performance S Series DAQ devices have the same basic features of a typical multifunction device – eight digital I/O lines, two counter/timers, two analog outputs, RTSI or PXI trigger bus for multidevice synchronization, and PFI lines for software-controlled routing of timing and triggering signals. S Series devices exceed the analog input performance of traditional multiplexed devices with features including: S Series Multifunction DAQ 12 or 16-Bit, 1 to 10 MS/s, 4 Analog Inputs Analog Input Sampling Input Analog Max Output Output Digital Counter/ Family Bus Inputs Resolution (bits) Rate (MS/s) Range (V) Outputs Rate (MS/s) Range (V) I/O Timers Triggers NI 6120 PCI, PXI 4 16 13 ±0.2 to ±42 2 41 ±10 82 2, 24-bit Analog, digital NI 6115 PCI, PXI 4 12 10 ±0.2 to ±42 2 41 ±10 82 2, 24-bit Analog, digital NI 6110 PCI 4 12 5 ±0.2 to ±42 2 41 ±10 8 2, 24-bit Analog, digital NI 6111 PCI 2 12 5 ±0.2 to ±42 2 41 ±10 8 2, 24-bit Analog, digital 14 MS/s single channel; 2.5 MS/s on two channels 2Hardware-timed up to 10 MB/s 3800 kS/s with NI-DAQmx, 1 MS/s with additional download.

  • Highly optimized FFT processing High-Performance Data Throughput Using NI-DAQmx driver software and S Series, you can take full advantage of your PC’s throughput potential, which is useful in many applications including transient recording. Flexible Data Transfer With NI-DAQmx, you can choose where to accumulate data – on the onboard memory, PC RAM memory, or PC hard drive memory. Thus, you can balance your PC application requirements and stream-to-disk/memory capabilities. In any case, NI-DAQmx optimizes data transfers by using DMA (direct memory access) and transferring large chunks of data, while ensuring no data loss. Y ou can also choose the format of your data, further optimizing throughput. Choices include raw (binary), scaled, or the high-level waveform data type. Using these techniques, you can achieve rates of more than 40 MS/s s ustained o ver the PCI/PXI bus to hard drive (depending on the PC). Data Compaction With the release of NI-DAQmx 7.4 or later, data compaction is available f or st ream-to-disk applications. The NI-DAQmx compaction feature strips unused or unwanted bits of data from each sample taken from your S Series device before it is permanently recorded to hard disk. This is helpful because hard drives are typically the throughput bottleneck compared to the PCI/PXI bus and PC RAM memory read/write speed. Using data compression, users with standard hard drives can see up to 20 percent higher throughput when streaming-to-disk. Signal Conditioning With the release of NI-DAQmx 7.4 or later, all S Series devices are compatible with parallel-mode SCXI modules. SCXI is limited to 100 kS/s for 16-bit accuracy and 333 kS/s for 12-bit accuracy when used in multiplexed mode. However, in parallel mode, the sample rate is limited by the maximum scan rate of the data acquisition device. When SCXI is used in parallel mode with S Series, all channels are simultaneously sampled and the sampling r ate is limited by the S Series device, from 250 kS/s per channel to 10 MS/s per channel. Measurement Services Software National Instruments measurement services software, built around NI-DAQmx driver software, includes intuitive application programming interfaces, configuration tools, I/O assistants, and other tools designed to reduce system setup, configuration, and development time. Automatic Code Generation – DAQ Assistant is an interactive guide that helps you navigate through configuring, testing, and programming measurement tasks and automatically generates the necessary code for LabVIEW, LabWindows/CVI, or Measurement Studio. Cleaner Code Development – Basic and advanced software functions have been combined into one easy-to-use yet powerful set to help you build cleaner code and move from basic to advanced applications without replacing functions. High-Performance Driver Engine – NI-DAQmx delivers maximum I/O system throughput with a multithreaded driver. Test Panels – With the M easurement & Automation Explorer configuration utility, you can test all of your module functionality before you begin development. Scaled Channels – Easily scale your voltage data into the proper engineering units using the NI-DAQmx Measurement Ready virtual channels by choosing from a list of common sensors and signals or creating your own custom scale. Data-Logging Software – VI Logger Lite is configuration-based software designed specifically for data logging. Features include easy logging and viewing of data, data extraction to Microsoft Excel, and code generation in LabVIEW. LabVIEW Integration – All NI-DAQmx functions create the waveform data type, which carries acquired data and timing information directly into more than 400 LabVIEW built-in analysis routines for display of results in engineering units on a graph. NI-DAQmx Base Driver NI-DAQmx Base (available at ni.com/downloads) offers Mac OS X and Linux users a programming interface similar to NI-DAQmx. It includes ready-to-use LabVIEW VIs and C function features similar to those included in NI-DAQmx driver software.
