TPCE-LE PCIe Data Acquisition card

Cost-Effective Data Acquisition card

TPCE-LE Modul

Description

The Elsys TPCE-LE data acquisition (DAQ) cards are 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-LE 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. This is the advantage of a modular data acquisition system.

TPCE-LE 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.

An engineer can either be efficient the very first day by taking advantage of the powerful Elsys Transient Recorder application software TranAX 3 or start the development of a custom software based on the C++/C# driver with sample programs for Windows and Linux. Especially for ATE and integrated system applications there is an IVI Scope Class driver and a LabVIEW instrument driver available. In all cases, the client-server architecture of the software allows to remotely control the TPCE modules over Ethernet with access from one or several clients.

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:

  • 200 mV, 400 mV, 1 V
  • 2 V, 5 V, 10 V
  • 25 V, 50 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.)
