34946A and 34947A Dual/Triple Microwave Switch Modules
34946A and 34947A SCPI Programming Examples
The programming examples below provide you with SCPI command examples
to use for actions specific to the microwave 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
three-digit channel number. For information on specific configurations, refer
to the simplified schematics in this chapter.
For complete information on the SCPI commands used to program the 34980A,
refer to the Agilent 34980A Programmer's Reference contained on the 34980A
Product Reference CD. For example programs, also refer to the 34980A
Product Reference CD.
Example: Closing channels You can use the

this "one-step" operation, the relays switch in the proper order that avoids
momentary connection of the wrong input to the switch output. The following
statement closes channel 201 of a microwave switch module installed in slot 5.
ROUTe:CLOSe (@5201)
Example: Querying channels for open or close state The following command
returns the open (1) or close (0) state of channel 202 for a module in slot 3.
ROUTe:CLOSe? (@3202)
Example: Querying the system for module identify The following command
returns the identify of the module installed in slot 7.
