2. Set the pulse generator to supply a TTL level pulse with 3 sec on time and 3 sec off
time.
3. Setup an alternate pattern with halves A and B as follows. Setup the A pattern to be
10101010 and the B pattern to be 11110000, both repetitive for a pattern length of
8bits.
4. Check the pattern on the oscilloscope and verify that it alternates between pattern A
and pattern B.
