Logic Operation
In logic operation, the oscilloscope performs logic operations on the logic levels of
the channel waveforms of source A and source B point by point and display the
results. When the voltage value of the source channel waveform is greater than the
corresponding threshold, it is regarded as logic “1”; otherwise logic “0”.
MSO4000/DS4000 provides the common logic operations as shown in the table
below.

Operation Description
AND
The results of logic AND operation of two binary bits are as follows:
A B A AND B
0 0 0
0 1 0
1 0 0
1 1 1
OR
The results of logic OR operation of two binary bits are as follows:
A B A OR B
0 0 0
0 1 1
1 0 1
1 1 1
NOT
The results of logic NOT operation of a binary bit are as follows:
A NOT A
0 1
1 0
XOR
The results of logic XOR operation of two binary bits are as follows:
A B A XOR B
0 0 0
0 1 1
1 0 1
1 1 0
