Spectrum trace markers
Automatic peak markers assist with quickly identifying the frequency and amplitude of peaks in the spectrum trace.
Figure 6: Spectrum trace markers
1. The Reference Marker is placed on the highest amplitude peak. It is marked with a Red triangle.
2. The Automatic markers mark the next highest peaks in the trace.
• The automatic markers indicate frequency and amplitude.
• Absolute readouts show the actual frequency and amplitude of the automatic markers.
• Delta readouts show the frequency and amplitude of the automatic markers relative to the reference marker.

This topic identifies objects in the RF waveform view.
1. Normal trace: Each acquisition is discarded as new data is acquired.
2. Max hold trace: The maximum data values are accumulated and displayed over multiple acquisitions of the Normal trace.
3. Min hold trace: The minimum data values are accumulated over multiple acquisitions of the Normal trace.
4. Average trace: Data from the Normal trace is averaged over multiple acquisitions. This is true power averaging, which occurs before
the log conversion. Each power of 2 averaging reduces the displayed noise by 3 dB.
5. Amplitude (magnitude) scale.
