5.6 Scope
The scope function is for sampling the selected objects’ value with a flexible sample cycle
(defined by Sample Time) and a flexible total sample number (defined by Samples) During
operation, if performance does not meet the requirement or any other unexpected behaviour
occurs, it’s highly advisable to use the scope function to do the analysis.

Figure 5-13 Scope window
Trig offset:
Number of samples before the trigger event occurs.
Object:
Maximum 64-bit length data can be taken in one sample, e.g.: 2 Int32 objects bit or 4 Int16 objects
Samples：The number of samples before the trigger source is triggered.
Trig source and Trig level：
The trigger condition is set in Figure 5-13 to start collecting data when
the effective target current q rises to 100DEC. DEC is the internal unit and can be switched to the
current unit.
Trigger edge：
clicking could change it to rising edge trigger 、falling edge trigger or rising and
falling edge trigger .
Single
： means sample for one trigger event only；
means sample continuously.
Zoom in/ Zoom out the oscillogram：Hold down the right mouse button and drag the
