SIGLENT
User Manual 113
Next, the measurement searches for the peak signal to build a list of peaks called a “signal list”. The
search is based on the defined peak excursion and peak threshold under menu Search. A cross mark
is added onto the trace for each peak signal found.
For each of the peak signals found, the instrument is tuned to the signal frequency in zero span and
dwells for the specified dwell time under menu Meas. Each signal in the list is updated with the final
detector and delta limit values when the final measurement is completed.
In some cases, you may not want to run the complete measurement, so you have the flexibility to control
the measurement routines. You can choose to just run scan, search, or the final measurement for only
certain specific signals in the signal list under menu Sequence.
The meters window on the right shows the instantaneous amplitude of each detectors. Similar to the
final measurement, meter consists of a zero span measurement on the specified meter frequency using
independent detectors and dwell times in menu Meter. Meter measurement is invalid during scan or a
final measurement.
