The Scope Window’s global toolbar impacts all displays. In addition, each display includes its own toolbar for
addressing parameters specific to that display. The secondary toolbar will be discussed shortly.

Item # Item Description
1 Start (Arm) Arms the acquisition device to acquire data. Data acquisition will commence as
soon as the triggering conditions are satisfied.
2 Manual Trigger Issues a Software Trigger to the data acquisition device. Whenever the device is
armed and waiting for a trigger, you can take this action to force data acquisition to
start.
3 Stop Stops receiving data. The data displayed will remain or will be discarded
according to the selection in the Display Preferences tab of the Options window.
4 Auto Rearm When enabled, the acquisition device is automatically re-armed whenever an
acquisition ends. With this feature, you can use the device as an oscilloscope to
display a rapid series of channel inputs.
Auto Re-Arm : Strip Charts, Scrolling Overlays, and Scrolling Block Updates will likely fail to
display the last block of data when auto rearm is used. This is because the automatic restart
of scrolling begins before the last data has had time to display. If this is undesirable you can
either (a) manually restart acquisitions instead of using auto rearm, or (b) use auto rearm, but
compensate for the restart/display aspect by acquiring an extra block of data.
5 Record (Direct to Disk) Provides a means of writing acquired data directly to disk files. The record
function makes use of DaqView’s Data Destination settings, with exception of Auto
Re-arm.
6 Gridlines On/Off Switches grid lines from On to Off or visa versa.
7 Cursors The Cursor button switches the cursor(s) from On to Off or visa-versa. Clicking
the adjacent down-arrow displays a pull-down list of the following cursor options:
Cursors On/Off - Switches the cursor(s) from On to Off or visa-versa.
Delta On/Off -Turns the Delta annotation function ON or OFF when in Dual Cursor
Mode.
Single Cursor - Implements Single Cursor Mode.
Dual Cursor - Implements Dual Cursor mode.
