A sweep is a series of consecutive measurements taken over a specified sequence of stimulus values. It
represents the basic measurement cycle of the analyzer.
The analyzer can perform sweeps at constant power but variable frequency (frequency sweeps), sweeps
at constant frequency but variable power (power sweeps), and sweeps at constant power and frequency
that are repeated in time (Time/CW Mode sweeps); see Sweep Type.
The sweeps are further specified by the number of measurement points, the total measurement time and
the trigger mode. A measurement may consist of a single sweep or a series of sweeps repeated
continuously.
On the other hand, depending on the measurement task and the measured quantity, the measurement at
each point can consist of several partial measurements with definite hardware settings.
The Sweep menu provides the following settings:
 Sweep Type defines the sweep variable (frequency/power/time/CW mode) and the position of
sweep points in the sweep range.
 Number of Points sets the total number of measurement points over the sweep range.
 Frequency Step Size sets the distance between two consecutive frequency sweep points.
 Sweep Time varies the measurement time for a sweep or delays the start of each sweep.
 Trigger selects the trigger mode for the measurement.
 Manual Trigger while the Manual trigger mode is active generates a trigger event. This softkey is
also available in the Trigger submenu.
 If Single (All Chans) is selected the measurement is terminated after a single sweep or a group of
single sweeps defined in the Define Restart dialog.
 Restart aborts the current measurement and restarts a new sweep sequence.
 Define Restart opens a dialog to specify which channels are affected and how many sweeps are
repeated.
 Define Busy Signal opens a dialog to configure the output signal at pin no. 4 of the USER
CONTROL connector.
Sweep Type
The Sweep Type submenu defines the sweep variable (frequency/power/time) and the position of the
sweep points across the sweep range.
