Markers Menu

(markers toolbar)

The markers toolbar at the top of the Marker menu selects the active marker, adds and removes markers, and changes marker visibility.

Couple Markers

Couple the selected marker number in all traces windows.

Hide Markers on All Traces

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 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./BW markers, specify the OBW reference power (percent), X dB Bandwidth Threshold (dB), 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.

Copy Marker to

Use the active marker value to set the value for many VSA parameters, such as Center Frequency and Reference Level.
