SCPI Programming Examples for the Matrix Modules

The programming examples below provide you with SCPI command examples to use for actions specific to the matrix switch modules.

The slot and channel addressing scheme used in these examples follow the general form sccc where s is the mainframe slot number (1 through 8) and

cccis the three- digit channel number. Channel numbers for the matrix modules are derived as follows:

Two-wire mode: The channel numbers for the 34931A, 34932A, and the 34933A (2- wire mode) are derived from the crosspoint or intersection of rows and columns, columns having two digits. See the example below.

Displayed Channel	Means This...
5304	A 34931A, 34932A, 34933A (2-wire mode) matrix
	module is in slot 5, crosspoint is row 3, column 4.
	It might be easy to remember this channel
	configuration as “srcc” (slot, row, column,
	column)

One-wire mode: The channel numbers for the 34933A (in 1- wire mode) are derived from a specific matrix number and the crosspoint or intersection of rows and columns on that matrix. See the example below.

Displayed Channel	Means This...
2437	A 34933A matrix module in 1-wire mode is in slot
	2, matrix of interest is 4, crosspoint is row 3,
	column 7. It might be easy to remember this
	channel configuration as “smrc” (slot, matrix,
	row, column)

For information on specific configurations, refer to the simplified schematics for the matrix modules. The schematics are 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.
