M8131A User Interface
Tool Bar
The tool bar provides the following convenient functions:
Capturing mode
This is an icon to mark the buttons to its right to be related to capturing. It
works in conjunction with single/continuous button. Its functionality expects
at least one selected channel (a channel can be selected from Acquisition Tab
> Channel Parameters > Display On check-box). The default state is “start”
which means by clicking, the current data buffer is cleared and a new
measurement, i.e. data capturing, is started. The measurement is performed:
•
Once only: if single measurement
was selected.
•
Continuously: if continuous measurement
was selected. Here the
measurement can be terminated by pressing stop button
At the end of
each measurement, the corresponding time and frequency signals of
selected channel(s) are plotted in trace windows.
Run
This icon enables you to start a repetitive capturing.
Stop
This icon enables you to stop a capture.
Single
This icon enables you to start a single capture.
Use mouse to control marker
If selected, a marker is added to the selected trace. Using the mouse, the
marker can be moved on the trace in order to read the value of desirable
points. To set the marker to a different channel, right click on graph panel
(the black area) and select the desirable channel number from Marker > Set
to Channel X. Set to Channel X is disabled if its corresponding channel
number from Acquisition Tab > Channel Parameters > Display On check-box
is not selected.
Use mouse to zoom
Use this tool to select a rectangular area of a trace for closer examination.
Auto scale once
Auto Scale adjusts All open windows’ scaling so that the whole traces are
visible. An auto-scale for one window can be done via Auto Scale inside
graph panel’s context menu (i.e. right-click and use context menu).
