Models LB480A/LB680A USB PowerSensor+™
Product Manual PPA (Pulse Profiling Application)
Edge Trigger
Allows the user to trigger on the positive or negative edge as required for best viewing.
Continuous Sweep
Causes the sensor to continuously deliver new traces.
Single Sweep
Delivers one new sweep each time it is pressed with the exception of the first time. Occasionally the first sweep
requires two button clicks.
Delay Trigger
Allows the user to delay the beginning of the trace from the trigger for up to 10 msec. This feature allows the user to
acquire high resolution traces long after the trigger has occurred.
Trigger Out
If this feature is enabled it causes a trigger to be passed to the trigger out port on the sensor (labeled TO). The trigger
out occurs somewhat differently for internal triggering than for External TTL triggering. When triggering internally
(manual or automatic) a trigger is sent out each time a sweep starts. When triggering on an external TTL trigger the
trigger is passed through to the trigger out port. The trigger out can also be inverted.
