Defining a Scan List
Advanced SCPI Operations 8-16
A Scan List may be defined using the SCAN command. The syntax
for the SCAN command is shown below:
[:ROUTe]
:SCAN <scan list>
:DELete
:SCAN?
The <scan list> is the same as a <channel list> used with the
CLOSE, OPEN, and PATH commands, but with one addition:
special keywords may be used to indicate that all channels
controlled by the 1256 are placed in the state as recalled from
nonvolatile memory.
In short, the <scan list> is comprised of:
A)
Individual channel designators. Examples:
B)
A list of single channels, separated by commas:
C)
A range of relays, separated by a colon:
D)
A path name:
E)
A state name. State names begin with the letters "STATE",
and end with a number between 0 and 100. The following
are valid state names:
STATE0
STATE7
State53
State100
For example, the commands:
PATH:DEF example,(@7(0,5,10,13))
SCAN (@1(323),4(0:2),5(8:5),example,
1(0),state14,1(224))
Define a path name ("example") and then define a SCAN list. Each
time a trigger is received, the next channel, path, or state in the
scan list is closed after the previous channel or path is opened.
