For complete command syntax, related information and examples of these and
other SCPI commands used to program the 34980A, refer to the Keysight 34980A
Programmer’s Reference which can be downloaded from www.keysight.com/find/
34980A.
Opening and Closing Channels
No physical matrix configuration changes are required for 1-wire versus 2-wire
operation. The SCPI commands alone determine if channels on paired matrices
are closed individually or in pairs. Therefore, individual 1-wire and 2-wire
commands can be combined in a program sequence.
One Wire Operation
The ROUTe:CLOSe and ROUTE:OPEN commands close and open a single
one-wire channel or list of one-wire channels.
Example 1: The example below opens a single crosspoint at row 3, column 1,
matrix M1L; with the module in Slot 1 and configured for 4x32 mode.
ROUT:OPEN (@1565)
Example 2: The example below closes a path containing two crosspoints. They
are at row 2, columns 2 and 34, matrix MH; with the module in Slot 2 and
configured for 4x64 mode.
ROUT:CLOS (@1302,1334)
Two Wire Operation
The ROUTe:CLOSe:PAIR and ROUTE:OPEN:PAIR commands close and open a
single two-wire channel pair or list of two-wire channel pairs. They apply only to
the following matrix modes, and operate channels in the listed paired matrices:
– 4x32: Paired matrices M1H and M1L; Paired matrices M2H and M2L
– 4x64: Paired matrices MH and ML
– 8x32: Paired matrices MH and ML
Example 1: The example below opens a single paired crosspoint at row 3,
column 1, matrices M1H and M1L; with the module in Slot 1 and configured for
4x32 mode.
