Here you can select which traces are to be displayed.
For further information about the traces see the glossary.
• +Pk, RMS, -Pk, MxP, MxR, AvR, MnR, MnP
• Enable All: Tap to select all traces
• Disable All: Tap to deselect all traces
• Inf. Mx/Mn: Tap to switch between On and Off
• Third Detector: Tap to select from dropdown menu: -Pk, Avg, or Smp.
To select the traces to be displayed:
You selected the desired view.
1. Tap the Traces button.
2. Tap one of the trace buttons to switch the trace On / Off.
3. Tap the Enable All button to display all traces.
4. Tap the Disable All button to hide all traces. At least the RMS trace remains visible as default.
5. To set the third director, tap the Third Detector button.
6. Press the Esc key to close the menu.
BACKGROUND There are three main detectors which compress all spectra occurring in the measurement time to one spectrum (per measurement time). The third detector can have various 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) |
