<ch_list>
Channel
List
One or more channels (for the multiplexer, actuator
and matrix switch channels), the r
ules are as
follows:
(@101): channel 01 on the module in Slot1;
(@101:103): channel 01 through 03 on the module
in Slot1;
(@101:103,301,406:408): channel 01 through 03 on
the module in Slot1, channel 01 on the module in
Slot3 and channel 06 through 08 on the module in
Slot4;
None
Explanation  For the multiplexer modules, if any channel on the module is defined to be part of the
scan list, attempting to send this command will result in an error.
 When the scan is initiated, the instrument will open all the multiplexer channels
(some multiplexer channels are added into the scan list).
 Sending this command will affect the relay cycle count (refer to the
DIAGnostic:RELay:CYCLes? command).
 For the matrix module, the channel number represents row number and column
number. For example, channel 126 represents the second row and six column on the
module in Slot1. For more information, refer to the User’s Guide.
 For the actuator module, the specified channels connect to the NC side after sending
this command.
 The instrument opens all the channels of the multiplexer, actuator and matrix switch
after a Factory Reset (the
*RST command). An Instrument Preset (the
SYSTem:PRESet command) does not affect the state of the channel relay.
Return
