Selecting the
Current Scan List
When the module is triggered it will execute the current scan list. After the
*RST
command or at power-up, the current scan list is List 1. To select
another scan list, execute the
ROUTe:SCAN <
scan_list
>
command.
•
The
<
scan_list
>
parameter can specify
LIST1
,
LIST2
,
LIST3
,
LIST4
,
or
LISTL
. You define
LISTL
as a list of scan lists when
LISTL
is the
current scan list.
•
ROUTe:SCAN
is not sequence sensitive. It can be executed at any time,
even while the module is scanning. Normally, the specified scan list
number becomes effective when the trigger system moves from the
initiated state to the waiting-for-trigger state. If
ROUTe:SCAN
is
executed after this point, it will become effective for the next scan. If
INITiate:CONTinuous
is
ON
and
TRIGger:SOURce
is
IMMediate
,
ROUTe:SCAN
will generate an error. See Figure 3-3.
To select scan list 2 as the current scan list:
ROUT:SCAN LIST2
Current scan list becomes 2 when
module initiated to wait-for-trigger.
