Disables marker visibility for all markers on all traces. Restore each marker's visibility individually by selecting the Visible checkbox for the marker on the selected trace.

   

Position

Configure trace markers and enable peak tracking and marker coupling.

 

 

Calculation

Enable band power calculation for markers, specify what a value to be calculated, and enable frequency counter.

 

 

OBW

Enable and set up the occupied bandwidth markers, specify the OBW Occupied bandwidth is closely related to channel power. It indicates how much frequency spectrum is covered by some given percentage (often 99%) of the total power of the modulated signal. reference power (in percent), and the centroid-to-center frequency function.

 

 

ACP

Enable and set up the Adjacent Channel Power Ratio markers, specify the reference channel BW, and up to 5 separate measurement adjacent channels.

 

 

Limits

Enables the Limit Test marker for comparing trace data to your defined limits and indicating a pass or fail condition.

 

 

Spectrogram

Select a trace in the spectrogram trace buffer for use with markers and to show in other trace windows with the same trace data.

 

 

Search

Move the marker to a specific X-axis location.
