产品描述
The OMB-DAQTEMP-14A data acquisition card provides a total hardware/software/signal conditioning solution for highaccuracy, high speed temperature, voltage, frequency, and pulse counting measurements, plus digital I/O and analog output.

A diversified software is included with the OMB-DAQTEMP-14A, including DaqView software, plus drivers for DASYLab, LabView, and WINOOWsbased languages including Visual Basic and C++.

OMB-DAQTEMP-14A hardware is comprised of a plug-n-play PCI board, 3 ft cable, and a screw terminal/signal conditioning pod. Cold-junction compensation is built-in to the OMB-DAQTEMP-14A, providing highly accurate thermocouple measurements, with channel-to-channel variation and noise typically less than 0.2°C, and absolute accuracy typically better than 1.0°C. This is accomplished by having a separate low-noise, bandwidth-limited amplifier per thermocouple channel. OMB-DAQTEMP-14A provides 14 thermocouple input channels. All power for the OMB-DAQTEMP-14A is derived from the PC, so there is no need for external power supplies or transformers.

In addition to thermocouple inputs, OMB-DAQTEMP-14A also provides 7 differential voltage input channels, with 16 bit resolution and programmable full scale input ranges from +156 mV to +10 V. The 4 frequency input channels can measure frequency or count pulses up to 10 MHz. Two timer output channels are capable of generating square outputs up to 1 MHz.

Twenty four digital I/O lines are also included, which can be programmed in 8 bit groups as either inputs or outputs.

The 16 bit/100K Hz analog outputs can be used to generate waveforms, with a virtually infinite waveform output length possible from PC memory.

All inputs and outputs are accessed via convenient screw terminals located on the signal conditioning pod. The cover of the signal conditioning pod is easily removable to gain access the screw terminals for signal connections.

DAQVIEW SOFTWARE
The included DaqView software allows you to verify signal connections, acquire and save data to disk, and graphically view realtime data within moments of taking your installing your system. Easily set up all your hardware, acquisition, and display parameters, without programming, via a simple spreadsheet-style screen. DaqView is a full featured acquisition and display application that provides all the functionality you’ll need for many datalogging applications.

SWD-DAQVIEW-XL
DaqViewXL is an optional Excel add-in that provides complete data acquisition functionality. Seamlessly integrated into Excel’s tool palette, DaqViewXL provides you with the same comprehensive acquisition and display capabilities as DaqView. Excel is an ideal tool for test engineers because it provides a variety of graph and charting functions for presenting data in a graphical format, as well as mathematical and analysis functions such as FFTs. Excel’s ability to retrieve and manipulate previously acquired data in a spreadsheet format and DaqViewXL’s advanced data acquisition functions form a comprehensive data acquisition solution.
