Changing attributes of an existing scan
When a scan already exists, changing channel attributes also causes the scan to change. Once a
scan list has been defined, the Model 707B or 708B tries to incorporate your changes into the scan. If
the change impacts the ability of the scan to function properly (such as deleting something referenced
by the scan), an error message is logged and the scan list may be cleared.
To see how the scan list may have changed, view the current scan list. On the front panel, press the
SCAN
key and select the
LIST
option, using the navigation wheel to scroll through the options. For
remote operation, use the
scan.list()
function.
You can clear an existing scan list before making any changes after making a scan list. From the front
panel, press the
SCAN
key and select the
CLEAR
option. For bus operation, use the
scan.create()
function.
To configure a scan from the SCAN ATTR MENU, while in an active scan list:
1. Press
the
CONFIG
key.
2. Press
the
SCAN
key. Modify any of the following menu items as desired:
•

MENU. If no scan list exists, pressing the
SCAN
key will briefly display "No Scan List. Use INSERT to
add selection."
