Setting Up a Burst Signal

Setting Up a Burst Signal

Task Set up a burst signal consisting of a 32-bit data pattern repeated twice at a period of 500 ps with 50 ps delay and 100 ps pulse width.

The data pattern is: 10100000000000000000000000000000

The amplitude is 2.0 V and the offset is 0 V.

Start the output at the rising edge of an external signal with 1 V threshold applied at the start input.
