Fig. 10-29: Internal trigger without offset measurement (P-0-0028; bit 1 = 0)
Note:
By parameterizing P-0-0036 (external trigger signal) in
P-0-0026, Oscilloscope: trigger signal selection it is
possible to release the internal trigger function by the external
trigger input.
When the kind of trigger "external trigger with offset measurement"
(P-0-0028; bit 1 = 1) has been selected, the internal and external trigger
are used for the master axis.
When "external trigger" has been selected, the behavior, until the internal
trigger event has been reached, corresponds to the behavior for the case
when trigger source "internal trigger" has been selected. Until the external
trigger signal occurs (P-0-0036; bit 0), the trigger offset between both
trigger events is determined and displayed in parameter P-0-0035. Then
the bit "trigger function completed" (P-0-0029; bit 3) is set in the status
word. The rest of the sequence is the same as in the case of internal
trigger source without offset measurement.
