Front panel keys to close and open channels – system channel operation (7702)
For remote programming, the following three commands are used for basic system operation
to open and close input channels:
ROUTe:CLOSe <clist> ' Close specified system channel
1
.
ROUTe:CLOSe? ' Query closed system channel
2
.
ROUT:OPEN ALL ' Open all channels.
1. Only one channel can be specified in the <clist>. For example, to close input channel
3 for a module in slot 1, the following command would be sent:
ROUTe:CLOSe (@103)
2. Only the closed system channel is returned by ROUTe:CLOSe?. The paired channel
for a 4-wire function is not returned. For example, assume channel 2 in slot 1 is
closed. The following response message will be returned:
(@102)
