Measurement
Different conditions can be set for the measurement. On the one hand, variable traces can be
recorded at the same time with one or more detectors. Alternatively, only the worst case
situation (peak detector) can be recorded. Afterwards each peak in the signal table will be
measured with QP and C-AV detector, as well. It is no longer necessary to perform a whole
trace with QP and C-AV (duration can be several hours) because these detectors are only
interesting when peaks are visible and the test engineer has the information in some minutes
and saves a lot of time during pre-compliance evaluation.
The number of readings in the signal table can be pre-defined. In order to get a detailed view
of a peak value, a zoom is available to enlarge a detailed view of a peak. After analysis, the
view can be zoomed out to get back the original view.
In case that the full screen of the trace is required, the measurement meter and the signal
table can be turned off on the screen.
