If the trace configurations "Average", "Max Hold" or "Min Hold" are set, the "sweep/
average count" also determines the number of averaging or maximum search proce-
dures (see
chapter 7.3.1.2, "Analyzing Several Traces - Trace Mode" , on page 455).
For details on how the number of sweep points and the sweep count affect the trace
results on the screen, see
chapter 7.3.1.1, "Mapping Samples to Sweep Points with the
Trace Detector" , on page 452.
6.5.1.9 How Often Data is Measured: Sweep Mode
How often the spectrum is swept depends on the sweep mode. Either a certain number
of sweeps can be defined ("Sweep Count") which are performed in "Single Sweep"
mode, or the sweep is repeated continuously ("Continuous Sweep" mode).
By default, the data is collected for the specified number of sweeps and the corre-
sponding trace is displayed. When the next sweep is started, the previous trace is
deleted.
However, the data from a single sweep run can also be retained and displayed
together with the new data ("Continue Single Sweep" mode). This is particularly of
interest when using the trace configurations "Average" or "Max Hold" to take previously
recorded measurements into account for averaging/maximum search (see
chap-
ter 7.3.1.2, "Analyzing Several Traces - Trace Mode" , on page 455).
6.5.2 Bandwidth, Filter and Sweep Settings
To configure the bandwidth, filter and sweep
Bandwidth and filter settings can be configured via the "Bandwidth" tab of the "Band-
width" dialog box.
Sweep settings can be configured in the Sweep dialog box or via the "Sweep" tab of
the "Bandwidth" dialog box.
1. To display the "Bandwidth" dialog box, do one of the following:
● Select "Bandwidth" from the "Overview".
● Select the BW key and then the "Bandwidth Config" softkey.
● Select the SWEEP key and then the "Sweep Config" softkey.
2. To display the "Sweep" dialog box, do one of the following:
● Select "Bandwidth" from the "Overview" and switch to the "Sweep" tab in the
"Bandwidth" dialog box.
● Select the SWEEP key and then the "Sweep Config" softkey.
The remote commands required to define these settings are described in chap-
ter 11.7.2, "Configuring Bandwidth and Sweep Settings" , on page 836.
How to perform a basic sweep measurement is described in chapter 5.2.1, "How to
Perform a Basic Sweep Measurement" , on page 115.
