Example
Suppose you have a pulse train where one of the pulses is of constant
duration (4
µ
s) and all other signals of interest are repeated with that pulse
train. See figure 17.
Pulse Train with Constant-Duration Pulse
To trigger the analyzer on that pulse, you can use the trigger setup in the
following table:
Source Operator and
Parameters
Pattern/Edge
Pattern 1 Duration > 3.9
µ
s H on channel 0, others don’t care
Example
Suppose you have a state machine whose three outputs, Q0 through Q2,
output the decimal sequence 0-1-6-0-6-1. Q2 is the most significant bit. See
figure 18.
Sequential Output from State Machine
If you try to trigger on any of the single output patterns 0, 1, or 6, the display
will not be stable. However, you can use the “Then” operator to trigger on the
sequence of pattern “0” followed by pattern “1.” If Q2, Q1, and Q0 are
connected to channels 2, 1, and 0 respectively, you can use the setup in the
following table to trigger the analyzer.
