The "Channel" menu provides all channel settings.
3.1.3.3
Active and Inactive Traces and Channels
A window can display several diagrams simultaneously, each with a variable number of
traces. One of these traces is active at each time. The
active trace
is highlighted in the
trace list on top of the active diagram (Trc3 in the figure below):
Tapping a trace in the list selects the trace as the active trace. Alternatively, use the
functions of the "TRACE > TRACE CONFIG > Traces" tab. If a previously inactive area
is selected as the active area, the trace that was active last time when the area was active
will again become the active trace.
The
active channel
is the channel which belongs to the active trace. The channels of all
traces in a diagram are listed at the bottom of the diagram, together with the "Stimulus"
values and the display colors of all traces. The active channel is highlighted (Ch1 in the
example below).
Tapping a trace in the trace list selects the channel associated to the trace as the active
channel. Channels with no traces are not indicated in the diagrams but can be accessed
via the "Channel Manager" dialog.
3.1.4 Sweep Control
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). The
sweeps are further specified by the number of measurement points and the total mea-
surement time.
By default sweeps are repeated continuously. Alternatively, a measurement may also
consist of a single sweep or of a specified number of sweeps.
