Keysight 34934A - Querying Channels for Open or Closed State

SCPI Programming 4
Keysight 34934A User’s Guide 231
ROUT:OPEN:PAIR (@1565)
Note the similarity in syntax to the 1-wire command; in any paired command, you
specify only the high channel in the pair. However, this command not only opens
channel 1565 on M1H, but also automatically opens paired channel 1629 on M1L.
Example 2: The example below closes a 2-wire path containing four crosspoints
(two pairs of channels). The crosspoints are row 2, columns 2 and 34, matrices MH
and ML; with the module in Slot 2 and configured for 4x64 mode.
ROUT:CLOS:PAIR (@1302, 1334)
Note the similarity in syntax to the 1-wire command. However, this command not
only opens channels 1302 and 1334 on M1H, but also automatically opens paired
channels 1366 and 1400 on M1L.
Querying Channels for Open or Closed State
One Wire Operation
The ROUTe:CLOSe? and ROUTe:OPEN? commands query the state of a single
one-wire channel or list of one-wire channels. It returns (for each channel in the
list) a “1” (true) of the channel is closed or a “0” (false) if the channel is open.
Example: The example below closes the crosspoint at row 4, column 2, matrix
MH; with the module in Slot 5 and configured for 8x32 mode. Then two queries
are sent, with the expected results.
ROUT:CLOS (@5402)
ROUT:CLOS? (@5402) !Returns a 1
ROUT:OPEN? (@5402) !Returns a 0
Two Wire Operation
The ROUTe:CLOSe:PAIR? and ROUTe:OPEN:PAIR? commands query the state of 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
