Global Toolbar Affects All Scope Window Displays

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.

Note: (a) Drag Channels from the Scan List to the Display Page, or (b) right-click on a channel and use the “move to” feature.

Description

Start (Arm)

Arms the acquisition device to acquire data. Data acquisition will commence as

soon as the triggering conditions are satisfied.

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.

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.

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.

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.

Gridlines On/Off

Switches grid lines from On to Off or visa versa.

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.
