DAQ-2000 Series
DAQ-2000 Series- The Smart DAQ Solutions
The DAQ-2000 series are the results of commitment and continuous effort in R&D to provide the high performance Data Acquisition (DAQ) solution. The innovative Carrier and Daughter Card design allows most advanced function integrated into a half-size PCI card and provide an easy migration path from PCI bus architecture to CompactPCI bus. In addition to the new innovations, DAQ-2000 series are geared toward to providing users with these added benefits:
High Immunity to Noise
The modular design of DAQ-2000 which separates the digital circuitry and analog device into two-board piggy-back configurations. The isolation of
digital and analog circuitry provides system best digital noise immunity. In addition, a special custom power regulation unit of the DAQ-2000 series are
implemented to provide a stable and clean power to the system. This DC/DC circuitry greatly reduces the noise induced from the power supply.
Custom Design Instrumentation Amplifier
Mostly commercial amplifiers are limited to frequency response lower than 1MHz. This makes scanning multiple channels at fast rates and high gain
with accurate data impossible. The custom design instrumentation amplifier provides fast setting time than commercial amplifiers that will
make the signal settle before going into the A/D converters.
Timer
Logic
Simultaneous Operation
DAQ-2000 series are capable to operate the analog input function and analog output function at full speed simultaneously. The special intelligent timing control logic and data buffer management allows high speed data I/O throughput at the same time. This allows accurate high speed measurement with no time delay.
Analog and Digital Triggering
The data acquisition can be started before or after the trigger event occur and the trigger signal can be analog threshold or digital signal. There are
four triggers mode available: Pre-trigger, Post-trigger, Middle trigger and Delay trigger. In addition, Post-trigger mode and Delay trigger mode allow
successively triggers to capture repeated burst of data.
DAQ-2000 series can sample channels in any order at the maximum conversion rate. Each channel can be configured with different gain, unipolar or bipolar, single-ended or differential and the information is stored in the channel gain queue. This allows fast and slow, large and small signals to be measured in one system.
The auto-calibration function of DAQ-2000 was performed with trim DACs to calibrate the analog input and analog output channels and the calibration value is stored in EEPROM. In addition to the auto-calibration, DAQ-2000 is self-calibrated. The onboard ultra-stable, on-board voltage reference is used for gain calibration and on-board circuit to ground the inputs for offset calibration. All the calibration can be conducted automatically by software command
DAQ-2000 series provides high speed signal bus for trigger and clock transmission. The allows multiple cards can be integrated into a system and provide card to card synchronization.
The Scatter-Gather Bus Mastering can transfer data to and from fragmented physical memory intelligently without CPU intervention. The DMA controller has a built-in linking table which tells the DMA controller the memory address and number of data to transfer and it can automatically load the next linking address to transfer data to and from the next memory segment. With this mechanism, Scatter-Gather Bus mastering allows the DMA controller transfer data to and from the memory up to the size limited by the system memory. Therefore it allows user to acquire high speed, huge number of data into the cost effective system memory..
The piggy-back configuration of DAQ-2010 not only minimizes the noise induced from digital circuitry but also reduce the size of the board. This allows DAQ-2000 can be integrated into half size computer chassis to meet the applications which space is a concern.
Easy Upgrade to CompactPCI Form Factor
By taking the advantage of carrier and daughter card design, DAQ-2000 is very easy to upgrade to CompactPCI form factor. Simply move the daughter card from PCI-bus carrier to CompactPCI-bus carrier and not a single line of program need to be modified, the DAQ-2000 family can be migrated to CompactPCI form factor, the cDAQ-2000 series.
