ROUTe:CHANnel:DRIVe:CLOSe:DEFault
Syntax
ROUTe:CHANnel:DRIVe:CLOSe:DEFault (@<ch_list>)
ROUTe:CHANnel:DRIVe:CLOSe:DEFault? (@<ch_list>)
Description
This command configures the specified channels on the 34945A Microwave Switch/Attenuator Driver to assume a default state of closed following the next boot (power) cycle, Factory Reset (*RST command), Card Reset (SYSTem:CPON command), or when the drive source is changed (see ROUTe:RMODule:DRIVe:SOURce[:IMMediate] command).
Used With:
34945A Microwave Switch/Attenuator Driver

Remarks
This command configures the specified channels to assume a default state of closed. Use the ROUTe:CHANnel:DRIVe:OPEN:DEFault command to assume a default state of opened.
You will normally want to send this command with the channel drive state disabled (see ROUTe:RMODule:DRIVe:SOURce[:IMMediate] command). When you change the drive state, all unverified channels on the specified module will be reset to their user-defined default values.
Channels that are configured for non-paired, pulsed operations with a default closed state will be pulsed once following a reset/boot.
The Factory Default for this attribute is open (channels assume an open state following a reset/boot). The ROUTe:RMODule:BANK:PRESet and SYSTem:RMODule:RESet commands will reset this attribute to the Factory Default open state, which overrides any previously-configured ROUTe:CHANnel:DRIVe:CLOSe:DEFault configuration.
As you reconfigure the module, be sure to keep the channels affected by the default state up-to-date. For example, when you reconfigure the drive attributes associated with a given channel, you will normally want to update the default state as well.
The default state is stored in non-volatile memory on the 34945EXT remote module.
Return Format
The query command returns "0" (OFF) or "1" (ON) for each channel specified. Multiple responses are separated by commas.
