Changing Attributes Of An Existing Scan; Front-Panel Scanning - Keithley 708B Reference Manual

Section 3: Functions and features

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:
•
ADD: Displays Use INS key. The related ICL is scan.add.
•
BYPASS: Enables (ON) or disables (OFF) bypassing the first step of the first scan pass. Related ICL
command: scan.bypass (on page 7-145).
•

•
