Scanning Commands

5
To create a scan list using:
•
a single channel, use
SCAN (@snn)
;
•
multiple channels, use
SCAN (@snn,snn...)
;
•
sequential channels, use
SCAN (@snn:snn)
;
•
groups of sequential channels, use
SCAN (@snn:snn,snn:snn)
;
•
or any combination of the above.
Any digital I/O lines included in scan_list must be operating in
handshake Mode #1 or #2. The 4-bit built-in digital I/O bits (091-094) can
be included in a scan_list.
N2260A and N2266A: The configuration must be specified before
defining the channels or channel range to be scanned. Page 130 describes
the configuration. The two tree relays (s98 and s99) can not be included
in a scan_list.
A scan list may contain up to 200 entries. One channel setup, regardless
of its channel number, is counted as one “channel” in a scan_list.
The
ROUTe:SCAN:LIST?
query returns the sequence of channels
included in the scan_list. A comma-delineated channel list is returned.
The list is in same order as in the scan_list and in the form of
(snn,snn,mm,...), where snn is the channel number and mm is a stored
channel setup.
The
ROUTe:SCAN CLEar
command clears the scan list. This command
has no effect on the scan configurations except clearing all the channels/
bits or the stored channel setups included in the <scan_list>.
The
ROUTe:SCAN:SIZE?
query returns the number of channels in the
scan_list. The returned value is an integer number between 0 and 200. A
stored setup in the scan is counted as one “channel”.
