5-80
The following examples demonstrate various forms for expressing channel entries for a scanlist.
Scanlist
1!6, 1!18, 2!3!6
Multiple channels separated by commas.
1!2:1!10
Range of channels (2 through 10).
1!2:1!10, 2!3!6
Range entry and single entry separated by commas.
1!30:1!40, 2!1:2!10
Range of multiplex channels (last 10 channels on card 1,
first 10 channels on card 2).
1!4!1:1!4!10, 2!1!1:2!1!10
Range of matrix channels (10 columns of row 4 on card 1,
10 columns of row 1 on card 2).
M36
Channel pattern stored at memory location M36.
The Scan List is not lost (cleared) after the instrument is turned off. However, the Scan List is
cleared if a channel in the Scan List becomes unavailable or restricted.
:POINts?
[:ROUTe]:SCAN:POINts?
Query scan list length
:scan:poin?
This query command is used to request the number of channels in the scan list. A channel pattern
(i.e. M1) in the scan list is counted as one channel. For example, assume the following scan list:
(@ 1!1:1!5, 1!10, M2)
After the POINt? command is sent and the Model 7001 is addressed to talk, the following mes-
sage will be sent to the computer:
7
The “7” indicates that the scan list length is seven channels.
10
OUTPUT 707; “:scan (@1!2, 1!4); scan:poin?”
20
ENTER 707; A$
30
PRINT A$
40
END
Line 10
:SCAN defines the scan list and POINts? queries the number of channels in the scan
list.
Line 20
Addresses the 7001 to talk.
Line 30
Displays (on the CRT) the number of channels (2) in the scan list.
