OVERVIEW
The upr-101 is a next-generation, high-speed waveform capturing platform. It includes patented flexible signal gating, intended for streamlining high-volume data acquisition tasks. The board includes two A/D channels.
Cards can be cascaded to deal with a large number of data acquisition channels in three basic modes: Normal (16 mux channels), Double Dynamic Range (2 x 8 bit data) or Double Sampling Rate (one-shot 200 MSPS). Up to 4 cards can be installed in one PC comprising powerful 64 channel flaw detector. Each channel contains 8 filters and a dynamic gain control (TCG) with a programming step of 160 ns.
Data is available in gated RF form where only the “interesting” portions of the signals are recorded. Simultaneously, the peak amplitudes and time tags of gated events in the signal are evaluated and stored. These measurements serve to streamline real-time applications where “decisions” can be generated without requiring software analysis of the waveform itself.
Gated RF data is transferred via the PCI bus in the DMA transfer mode; gated measurements can also be transferred in Memory Map read commands.
Data transfer rates are only limited by the PCI bus; 70-80 Mb/s have been recorded in practical applications.
The upr-101 is equipped with three triggering modes: internal (free-running at specified frequency), external, or software trigger.
In all the triggering modes it is possible to initiate data acquisition in pre-trigger, normal, delayed trigger or threshold trigger storage. Gated threshold event triggers are provided for each gate to allow tracking of multiple signals in a single waveform.
