TRC+ Internal signal trace function with additional automatic determination of
the characteristic quantities
The SinuCom NC internal trace function is started when the data trace is
started and the signals, relevant for the specific test step, recorded. The trace is
automatically terminated after the appropriate (expected) signal changes and
transitions and the appropriate characteristic quantities are automatically
determined and displayed for the test. It is not necessary to manually terminate
the trace.

TEXT
The operator is prompted, step-by-step when carrying-out a test. The
following secondary conditions must be observed, especially for those
tests that use the internal trace function:
If a traversing direction has been selected, then this must also be taken
into account for the subsequent task. The reason for this is that the
trigger condition for the automatic data acquisition and evaluation is
based on this direction data.
A procedure is initiated to activate the trace function using the button
<start data acquisition>. This can take several seconds. The signal is
only acquired after the appropriate message in a message box.
If the trace has to be manually terminated, then this step should, if at all
possible, be made directly after the last expected signal change that is
relevant for the trace. This ensures that the relevant area is optimally
displayed in the subsequent trace display.
For each test step, the operator must decide as to whether the test was
successfully carried-out. He should make this decision based on traced
and determined data and test situations that have been carried-out and
documented. This can be confirmed after the test has been carried-out by
selecting the appropriate results.
