Data Acquisition Card - TPCE

TPCE Data Acquisition Card

The Elsys TPCE data acquisition (DAQ) cards are high-precision and high-resolution digitizers with sophisticated features such as advanced trigger mode, continuous data acquisition mode, differential inputs, digital input lines (Markers) and ICP coupling for powering piezo sensors.

The various TPCE cards are compact short-form PCI Express (PCIe) card. A scalable data acquisition system may be started with one or several cards that can be extended in the future to build a solution with up to 64-channels in one housing.

Data Acquisition

TPCE cards are equipped with four analog-digital converters in the case of 4-channel cards and eight converters for 8-channel cards. This allows to use the full converter speed with all channel active. Cards with different sample rates and different resolution may be mixed to match the application needs.

Key Specification

  • Up to 240 MS/s per channel sample rate
  • 14-bit and 16-bit vertical resolution
  • Advanced triggers
  • 4-, or 8-channel single ended and differential cards
  • High-precision typ. 0.03 % of FSR
  • 100 mV to 100 V input range
  • 0 to 100 % offset
  • Very low input noise
  • High differential CMRR
  • Anti Aliasing Filter (optional)
  • IEPE/ICP 4mA Current Source (optional)

Aliasing

From Wikipedia, the free encyclopedia

Temporal aliasing is a major concern in the sampling of video and audio signals. Music, for instance, may contain high-frequency components that are inaudible to humans. If a piece of music is sampled at 32000 samples per second (sps), any frequency components above 16000 Hz (the Nyquist frequency) will cause aliasing when the music is reproduced by a digital to analog converter (DAC). To prevent that, it is customary to remove components above the Nyquist frequency (with an anti-aliasing filter) prior to sampling. But any realistic filter or DAC will also affect (attenuate) the components just below the Nyquist frequency. Therefore, it is also customary to choose a higher Nyquist frequency by sampling faster.

Input Range

The possibility to configure the input range allows to use the full 14 or 16 Bit analog-digital converter resolution for different input signal levels.

The following input ranges can be set individualy on each channel:

  • 100 mV, 200 mV, 500 mV
  • 1 V, 2 V, 5 V
  • 10 V, 20 V, 50 V, 100 V

Offset Setting

The offset setting allows to adapt the input range to your signal polarity. Example: 10 V input range and 0 % offset gives an input range of 0 to 10 V. 50 % offset means -5 to 5 V input range and 100% means -10 to 0 V input range.

The offset has a resolution of 1 % and can be set per channel.

Common-mode rejection ratio

From Wikipedia, the free encyclopedia

The common-mode rejection ratio (CMRR) of a differential amplifier (or other device) is the tendency of the devices to reject the input signals common to both input leads. A high CMRR is important in applications where the signal of interest is represented by a small voltage fluctuation superimposed on a (possibly large) voltage offset, or when relevant information is contained in the voltage difference between two signals. (An example is audio transmission over balanced lines.)

Other Specification

  • Up to 1 GB memory
    (128 MS per channel)
  • PCIe 1.1, x4 lane, 2.5 GBit/s
    (10x faster than PCI Bus)
  • Short form PCIe data acquisition card
  • Continuous data streaming with up to 120 MS/s per channel.

Software

TPCE data acquisition cards can be used with several different software solutions:
