Occupied Bandwidth Measurement
Sweep/Control
Sweep/Control
Displays a menu of functions that enable you to set up and control the sweep time and source for the
current measurement.
For details about this key, see “Sweep/Control” on page 1267.
Sweep Time
Selects the length of time in which the spectrum analyzer sweeps the displayed frequency span.
Additional overhead time, which impacts the sweep rate, is not calculated as part of the sweep time. In
fact:
• sweep rate = span/sweep time
• update rate = 1/(sweep time + overhead)
• sweep cycle time = sweep time + overhead
Sweep time is coupled to RBW and VBW, and is impacted by the number of sweep points, so changing
those parameters may change the sweep time.
This function is not available when the selected input is I/Q.
