•
At the end of the scan, the last channel that was scanned will be
opened (as well as any Analog Bus relays used during the scan).
Any channels that were opened during the scan will remain open at
the completion of the scan.
•
If you abort a scan that is running, the instrument will terminate any
reading in progress (readings are not cleared from memory). If a scan
is in progress when the command is received, the scan will not be
completed and you cannot resume the scan from where it left off.
Note that if you initiate a new scan, all readings are cleared from memory.
•
You can use either the internal DMM or an external instrument to make
measurements of your configured channels. However, the 34980A allows
only one scan list at a time; you cannot scan some channels using the
internal DMM and others using an external instrument. Readings are
stored in 34980A memory only when the internal DMM is used.
•
The Monitor mode is automatically enabled on all channels that are
part of the active scan list (see
“Monitor Mode”
on page 63).
•
The present scan list is stored in volatile memory and will be lost when
power is turned off or after a Factory Reset (
*RST
command).
Adding Channels to the Scan List
Before you can initiate a scan, you must set up a scan list to include all
desired multiplexer or digital channels. Channels which are not in the
scan list are skipped during the scan. By default, the instrument scans the
list of channels in ascending order from slot 1 through slot 8 (channels
are reordered as needed).
To Build a Scan List From the Front Panel

.
Then select the function, range, resolution, and other parameters for
this channel. Then add the channel to the scan list by selecting:
