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 ccc is 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.
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.
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.
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)
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)
