BACKGROUND

There are three main detectors which compress all spectra occurring in the measurement time to one spectrum (per measurement time), while the third detector can have different functions.

Basis Traces:

      Detector 1: +Pk (Plus Peak)

      Detector 2: RMS

      Detector 3: The function of the third detector can be set via the context menu as follows:

      -Pk (Minus Peak)

      Avg (Average)

      Smp (Sample)

 

In order to be able to view very fast signals with the naked eye (the measurement time is partly 10 ms), there is a downstream compression for these detectors, which the user can display as an additional trace.

The compression time is determined by the Scan Count. After the Scan Count has elapsed, the signal then decays exponentially.

 

Example:

      Measurement Time: 10 ms

      Scan Count: 300

      Trace: MxP

 

Over the time of 10 ms x 300 = 3 s, the data of the +Pk (Plus Peak) become summarized in a Trace (in this case, the maximum values that have occurred during this time). If the signal would no longer be present after the 3 s, the Trace would slowly fade away. In this way, short pulses, for example, can be made visible.

Calculated traces:

      Detector 1: MxP (Maximum of Plus Peak)

      Detector 2:

      MxR (Maximum of RMS)

      AvR (Average of RMS)

      MnR (Minimum of RMS)

      Detector 3 (depending on the configuration):

      MnP (Minimum of Minus Peak)

      MxA (Maximum of Average)

      MxS (Maximum of Sample)
