| BITSCOPE | design | The Capture Engine |
|
Bitscope uses a Microchip 16F628 PIC and a Lattice LSI 1032 PLD to implement a high speed dual stream data capture engine. Captured data is recorded to two 32k x 8 bit SRAM buffers.
Bitscope Block Diagram One stream is a high speed 8 bit A/D convertor. The other records 8 inputs from the digital POD. The captured analog and digital data is uploaded to a host computer for analysis and display. In addition to data capture functions, Bitscope has a frequency counter that ranges from a Hz to GHz, and an interval and period timer that can time periods from nanoseconds to years (if you have the time :-). Bitscope also has sophisticated programmable triggers on both the analog and digital inputs. |
