IEEE-488 Bus Commands —

 

 Over the bus, the :CLOSe 

and :OPEN commands are used to control channels. Exam-
ples: 

:CLOSe (@ 4!1, 4!5)

Close channels 1 and 5 of Slot 4.

:OPEN (@ 4!1, 4!5)

Open channels 1 and 5 of Slot 4. 

:OPEN ALL

Open all channels. 

 

Scanning channels

 

Channels are scanned in the order that they are presented in 
the Scan List. To perform a scan, first program the control-
ling aspects of the scan (see Table 4), and then press (or 
click) STEP to take the Model 7002 out of the idle state 
(ARM indicator on). 

Regardless of how the scan is configured, the STEP key (or 
LED) is always active allowing you to manually step 
through the scan. The scan can be terminated at any time by 
pressing (or clicking) OPEN ALL. All closed channels will 
open and the Model 7002 will return to the idle state (ARM 
indicator off). 

 

IEEE-488 bus commands —

 

 Over the bus, a scan is con-

figured using the Trigger Subsystem commands (see Table 
16). The following command starts the scan by taking the 
Model 7002 out of the idle state:
