Switching a Relay Channel
Switch modules can be used to route signals to and from your test
system. This is achieved by closing or opening the relay channels on
these modules.
•
From the front-panel, you can open or close one relay channel at a
time. However, over the remote interface, multiple relay channels can
be operated by a single command if a channel list is specified. In
addition, these open or closed states can be stored, and a stored
channel setup can be included in a scan list (see “State Storage” on
page 106).
•
Whenever a switch module is reset, all of the closed relay channels on
the module will be opened.
•
Whenever the instrument is turned on or reset, all of the closed relay
channels in the instrument will be opened.
•
Front-Panel Operation: Select a channel, press Open or Close.
Select a slot, press and hold Card Reset to open all channels on the
selected module.
Press Shift, then press and hold Card Reset to open all channels in
the instrument.
•
Remote Interface Operation: The following commands open and close
multiple channels on the modules in slots 1 and 2.
OPEN (@101,103:107,207)
! Open multiple channels.
CLOS (@101,103:107,207)
! Close multiple channels.
SYST:CPON 1
! Open all channels on the
module in slot 1.
Note When an Agilent N2260A or N2266A is configured to the 1-wire mode,
only one channel on the module can be closed at a time.
