ROUTe:CHANnel:DRIVe:OPEN:DEFault

Syntax

ROUTe:CHANnel:DRIVe:OPEN:DEFault (@<ch_list>)

ROUTe:CHANnel:DRIVe:OPEN:DEFault? (@<ch_list>)

Description

This command configures the specified channels on the 34945A Microwave Switch/Attenuator Driver to assume a default state of open 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

This is a required parameter

Remarks

  • This command configures the specified channels to assume a default state of opened. Use the ROUTe:CHANnel:DRIVe:CLOSe:DEFault command to assume a default state of closed.

  • 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.

  • For channels that are configured for non-paired, pulsed operations with a default open state, no action will be taken (these channels may only be closed).  

  • 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.

  • 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.  

Examples

The following program segment configures the default state on channels 01 and 02 on Bank 2 on 34945EXT remote module #2 (slot 3).  

ROUT:CHAN:DRIV:OPEN:DEF (@3201,3202)  !Set default state
ROUT:RMOD:DRIV:SOUR INT,(@3200)  !Drive channels opened

The following query returns the default state of channels 01 and 02 on Bank 2 on 34945EXT remote module #2 (slot 3).

ROUT:CHAN:DRIV:OPEN:DEF? (@3201,3202)

Typical Response:  1,1
