Non-Sequential Scanning

By default, the instrument scans the list of channels in ascending order from slot 1 through slot 8 (channels are reordered as needed). If your application requires non- ordered scanning of the channels in the present scan list, you can use the non- sequential scanning mode.

This feature is available from the remote interface only.

•The scanning mode applies to the entire mainframe and cannot be selectively used on individual modules.

•When sequential scanning is enabled (default), the channels in the scan list are placed in ascending order from slot 1 through slot 8. Duplicate channels are not allowed. For example, (@2001,1003,1001,1003) will be interpreted as (@1001,1003,2001).

•When sequential scanning is disabled (OFF), the channels remain in the order presented in the scan list (see exception below). Multiple occurrences of the same channel are allowed. For example, (@2001,2001,2001) and (@3010,1003,1001,1005) are valid and the channels will be scanned in the order presented.

•When you specify a range of channels in the scan list, the channels are always sorted in ascending order, regardless of the scan order setting. Therefore, (@1009:1001) will always be interpreted as 1001, 1002, 1003, etc.

•If you define a scan list with the sequential mode enabled and later disable the mode, the scan list will not be reordered; however, the scan list will be treated as a non- sequential list thereafter.

•If you have defined a scan list with the sequential mode disabled (OFF) and later enable the mode, the channels will be reordered.

•Non- sequential scan lists are not stored as part of the instrument state by the *SAV command; in this case, the ordered mode will be enabled and the scan list will be empty when the instrument state is restored (*RCL command).
