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:
1. Press the
SCAN
key when on the main display.
2. Select the
LIST
option and press the
ENTER
key.
3. Use the navigation wheel or
CURSOR
keys to scroll through the list.
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:
ADD
: Displays
Use INS
key. The related command is
scan.add
.
BYPASS
: Enables (ON) or disables (OFF) bypassing the first step of the first scan pass.
(on page 7-140).
MODE
: Sets the scan mode value to one of the following:
•
OPEN_ALL (default setting)
•
OPEN_SELECT
(on page 7-145).
3. Press the
EXIT
key
to leave the menu.
Front-panel scanning
After channels have been added to the scan list, press the
SCAN
key to display the SCAN ACTION
MENU. If no scan list exists, pressing the
SCAN
key will briefly display "No Scan List. Use INSERT to
add selection."
