Switch Control Commands

ROUTe

 

 

:CLOSe (@<x

>)

 

:CLOSe:EXCLusive (@<x

>)

:CLOSe? (@<x

>)

 

Close the specified channels on a multiplexer or switch module. If any multiplexer channels are configured to be part of the scan list, you cannot close multiple channels on that module; closing one channel will open the previously closed channel. On the other modules, you can use the :EXCL command to ensure that all channels are open before closing the specified channel. The :CLOS? query returns the state of the specified channels. Returns “1” if the channel is closed or “0” if the channel is open.

On the 20-channel multiplexer (HP 34901A), only one of the shunt switches (channels 21 and 22) can be closed at a time; connecting one channel will close the other.

On the matrix module (HP 34904A), you can close multiple channels at the same time.

∙ On the RF multiplexer modules (HP 34905A/6A), you can close

5

one channel per bank at a time; closing one channel in a bank will

 

open the previously closed channel. One channel in each bank is

 

always connected to COM. These modules respond

to the

 

ROUT:CLOSe command. To open a channel, send the ROUT:CLOSe command to another channel in the same bank.

ROUTe

:OPEN (@<x >)

:OPEN? (@<x >)

Open the specified channels on a multiplexer or switch module.

The :OPEN? query returns the state of the specified channel. Returns “1” if the channel is open or “0” if the channel is closed.
