a) The sweep is started by pressing the START key in the top right part of the
front panel. The status message "Sweep Run Cont" informs the user that when
this key is pressed the sweep will start and be repeated continuously.
b) The sweep can be stopped at any time by pressing the STOP CONT key (the
status message "Sweep Stopped" is displayed); the sweep continues if the key
is pressed again.
c) If the SINGLE key is pressed, the sweep is started
once
only; "Sweep Termi-
nated" appears in the status field when the sweep cycle has been terminated.
6. Step: Displaying the measurement results – Graphical windows
The results of a frequency response measurement are usually displayed graphi-
cally with the measured output voltage values of the DUT being plotted on the fre-
quency axis.
The following settings are required for this:
a) To avoid overloading screen 1 with too many panels, change to screen 5 to dis-
play the graphical representation.
b) Open the menu bar and, from the selection list under the "DispConfig" button,
select the "Sweep Graph 1 Config" panel. As explained above, the way in
which the measurement results are presented is determined in the configura-
tion panels. Each graphical window has its own configuration panel. The
"Sweep Graph 1 Config" panel required here has two columns, but only Trace
A is shown to provide a better overview.
c) The associated graphical window can be opened using the "Show" button in
the "Display" field. The window appears in the same screen so that the effect of
the following settings can be observed directly.
In each graphical window, one or two traces (Trace A and Trace B) can be plot-
ted on one x
‑
axis. Each trace can consist of a large number of scans. In this
example, only one single scan is to be displayed; the "Scan" field can therefore
remain set to "Single".
