Agilent 34937A-34939A General Purpose Switch Modules User’s Guide
34937A, 34938A and 34939A SCPI Programming Examples
34937A, 34938A and 34939A SCPI Programming Examples
The programming examples below provide you with SCPI command 
examples to use for actions specific to the general purpose switch 
modules.
The slot and channel addressing scheme used in these examples follow the 
form  sccc  where  s is the mainframe slot number (1 through 8) and ccc is 
the channel number.
For complete information on the SCPI commands used to program the 
34980A, and for example programs, refer to the Agilent 34980A 
Programmer’s Reference contained on the 34980A Product Reference CD.
Opening and Closing Channels 
Example: Closing and opening channels 
The first two commands close 
channel 3 for a module in slot 2, then channel 5 for that module. 
 
The last command opens both channel 3 and channel 5. 
ROUTe:CLOSe (@2003)
ROUTe:CLOSe (@2005)
ROUTe:OPEN (@2003,2005)
Example: Querying channels for open or closed state 
The following command 
returns a 1 (true) or 0 (false) state of channel 016 for a module in slot 3. 
ROUTe:CLOSe (@3016)
ROUTe:CLOSe? (@3016) !Returns a 1
ROUTe:OPEN? (@3016) !Returns a 0
Reading Jumper State and System Identity
Example: Querying the power-failure state of 5 A relays 
The following command 
returns the position of the power- fail jumper, either “MAIN” (all relays 
maintain their present state when power fails) or “OPEN” (all relays open 
when power fails) for a module in slot 4. If this command is sent to a 
module other than the 34937A or 34938A, “NONE” is returned (no error is 
generated). In particular, the position of the power- fail jumper on the 
34939A module cannot be queried using this commmand.
SYSTem:MODule:PFAil:JUMPer:AMP5? 4
Example: Querying the system for module identify (all modules) 
The following 
command returns the identify of the module installed in slot 7. 
SYSTem:CTYPe? 7
