Section 4: Closing and Opening Switching Module Channels Series 3700 System Switch/Multimeter User's Manual4-6 Document Number: 3700S-900-01 Rev. A / August 2007Available commands for measuring: dmm.close dmm.open scanning (only with function of DMM configuration set to anything other than 'nofunction')ICL Action performeddmm.close Equivalent of channel.exclusiveslotclose except it also prepares theDMM for taking a measurement on the function associated with theitem. For a channel, it will make sure the DMM is connected throughthe backplane. However, it will not do this for a channel pattern. It willclose any needed backplane relays and paired channel. It will openchannels and backplane relays that will interfere with measuring on thespecified channel.dmm.open For a channel, it will open the channels that would get closed withdmm.close. For channel pattern, it will open the items associated withthe image of the pattern.Close/open bus operationUse the following commands to control switches over the bus. For detailed informationspecifying what happens with each of these commands, see the reference manual.ICL Description Usagechannel.close Function: Closes specifieditems in ch_list withoutopening any channels.channel.close(ch_list)ch_list: string listing the items to close.Items can include channels, backplanerelays, and channel patterns.channel.open Function: Opens itemsspecified in ch_list.channel.open(ch_list)ch_list: string listing the items to open.Items can include channels, backplanerelays, and channel patterns.dmm.close Function: Closes thespecified channel or channelpattern in preparation for aDMM measurement.dmm.close(ch_list)ch_list: string listing the channel or channelpattern to closedmm.open Function: Opens thespecified channel and/orchannel pattern.dmm.open(ch_list)ch_list: string listing the channel or channelpattern to open
