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.

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.
