TPCE-LE PCIe data acquisition waveform digitising products are suitable where the acquisition of high speed, high resolution and high precision waveform data is required. Features include advanced trigger modes, continuous data acquisition mode, single ended and differential inputs, digital input lines and ICP coupling for powering piezo sensors. They enable the development of scalable systems that can be expanded to meet growing data acquisition needs.

TranAX-LE operating and analysis software comes with each board, as well as a LabVIEW Instrument driver, C++/C# and IVI scope class driver. As with Elsys’ existing TPCX and TPCE platforms, the TPCE-LE modules can be housed in any existing TraNET system:

TraNET FE transient recorders that hold four to 32 single-ended channels or two to 16 differential channels;
TraNET EPC industrial computer frame with 16 slots for a total of 64 channels;
TraNET PPC ruggedized portable computer system with six slots for a total of 24 channels.

All Elsys recorders feature input channels with the ability to be individually triggered. For example, four full trigger circuits are available on a four-channel recorder to obtain logic triggering such as “AND” and “OR”.

Synchronisation can be established with many associated channels. Advanced trigger modes include slew rate, pulse width, pulse pause, period, missing event, window-in and window-out as well as the usual edge pos/neg triggering with trigger hysteresis values set by the user.

For troubleshooting applications, event controlled recording (ECR) mode, requires a trigger event, but eliminates the dead time between triggers using an overlapping technique of adjacent acquisitions.
