Step 2.
Trigger Level Setup
Click the drop down menu of Trigger Level on Ports A , B , C and D to select
the Trigger Level as the voltage level that a trigger source signal must reach
before the trigger circuit initiates a sweep.
Tip:
There are four commonly used preset voltages for Trigger Level, TTL,
CMOS (5V), CMOS (3.3V), and ECL. Users also may define their own
voltage from -6V to +6V to fit with their DUT.
Port A represents the pins from A0 ~ A7 on the signal connector of the Logic
Analyzer, and so do Ports B, C and D. The voltage of each port may be
configured independently.
