Using Markers:

Markers are used to precisely measure points on the spectrum trace.

• Press the Marker button.
• Use the navigation keys or rotary knob to move the marker to the desired point.
• The frequency and amplitude values at the marker's position will be displayed.

Measurement Functions:

The SSA3032X includes various automatic measurement functions:

• Channel Power: Measures the total power within a specified channel bandwidth.
• Adjacent Channel Power Ratio (ACPR): Measures the ratio of power in an adjacent channel to the power in the main channel.
• Occupied Bandwidth (OBW): Measures the bandwidth containing a specified percentage of the total power.
