Overview
The TH80 is a dual channel high-speed digitizer of very high input
bandwidth and up to 80MHz sampling speed. A 32MB on-board DDR RAM allows
the capture of long burst at the full 80MHz sampling speed. Control
registers are mapped on the 32-bit OMNIBUS interface and control is
commanded via software on the host card.
The card can be used for fast signal digitizing between 1 and 80MSPS,
acquiring gap-free burst length of up to total on-board RAM capacity. Data
can then be transferred at the lower OMNIBUS rates to the mother board for
post-processing and/or bus-mastering to host PC memory. The A/D conversion
clock source is selected between an on-board oscillator (default 80MHz) or
an external TTL clock. Error correction is performed in the logic with
first order equation where gain and offset coefficients can be written via
SW to on-board ROM. |
