ROUTe:RMODule:DRIVe:SOURce[:IMMediate]

Syntax

ROUTe:RMODule:DRIVe:SOURce[:IMMediate] <source>, (@<rem_ch_list>)

ROUTe:RMODule:DRIVe:SOURce[:IMMediate]? (@<rem_ch_list>)

Description

This command selects the power source for driving channels on the specified 34945EXT remote module connected to the 34945A Microwave Switch/Attenuator Driver. The INTernal source is available only for the 34945EXT Master module, which can be powered directly by the 34980A. Each of the 34945EXT Slave modules must be powered by an EXTernal source that you apply to the module. For more information on connecting an external power source to the module, see the Agilent 34980A User's Guide.

Used With:

  • 34945A Microwave Switch/Attenuator Driver

Parameters

Name

Type

Range of Values

Default Value

<source>

Discrete

{OFF|INTernal|EXTernal}

OFF (all switching is tri-state)

<rem_ch_list>

Numeric

One or more 34945EXT remote module identifiers in the form (@sr00).

Select from s100 through s800.

This is a required parameter.

Remarks

  • Use the ROUTe:RMODule:DRIVe:SOURce:BOOT command to define which channel drive source will be used following the next boot (power) cycle or Factory Reset (*RST command).

  • When you change from one channel drive source to another (including from OFF to INTernal or EXTernal), all unverified channels on the specified module will be reset to their user-defined default values (see ROUTe:CHANnel:DRIVe:CLOSe:DEFault and ROUTe:CHANnel:DRIVe:OPEN:DEFault commands).

  • Channels on which verification is enabled (see ROUTe:CHANnel:VERify[:ENABle] command) are not driven when the ROUTe:RMODule:DRIVe:SOURce[:IMMediate] command is sent with the INTernal or EXTernal source. In this case, the verified state is simply assumed by the module.

  • If a number of channels are configured for long pulse widths (see ROUTe:CHANnel:DRIVe:PULSe:WIDTh command) and recovery times (see ROUTe:CHANnel:DRIVe:TIME:RECovery command), this command can take as long as 30 seconds to complete.

  • The factory default state is set to OFF to ensure that no external microwave devices will be driven until you specifically enable the desired power source.

  • By setting the channel drive source to OFF, all channel drives go to a tri-state mode regardless of whether the outputs are configured for the TTL or open-collector mode. An error will be generated if you attempt to operate channels while the power source is OFF.

  • When the channel drive source is set to OFF, the position indicator LED drives are also disabled (see ROUTe:RMODule:BANK:LED:DRIVe[:ENABle] command).

  • The following commands require that the channel drive source be OFF in order to allow reconfiguration:

    ROUTe:CHANnel:DRIVe:PAIRed[:MODE]

    ROUTe:CHANnel:DRIVe:PULSe[:MODE]

    ROUTe:RMODule:BANK:DRIVe[:MODE]

    ROUTe:RMODule:BANK:PRESet

Return Format

The query command returns "OFF", "INT", or "EXT" for the specified channels. Multiple responses are separated by commas.

Examples

The following command selects the EXTernal source on 34945EXT remote module #2 (slot 3).

ROUT:RMOD:DRIV:SOUR EXT,(@3200)

The following command returns the drive source on 34945EXT remote module #2 (slot 3).

ROUT:RMOD:DRIV:SOUR? (@3200)

Typical Response:  EXT
