Syntax

ROUTe:CHANnel:DRIVe:STATe? (@<ch_list>)

Description

This command returns the current drive state of the specified channels on the 34945A Microwave Switch/Attenuator Driver. This command is provided specifically for the verified, single-coil, non-pulsed channel drive configuration, where the results from the ROUTe:CLOSe? command reports the verified position indicator state, which may not be the same as the current drive state. The response from the ROUTe:CHANnel:DRIVe:STATe? command indicates whether or not the specified channels are currently being driven.

Used With:

• 34945A Microwave Switch/Attenuator Driver

Parameters

Name	Type	Range of Values	Default Value
<ch_list>	Numeric	One or more channels in the form (@srcc).   Bank 1: sr01 through sr08 sr11 through sr18 Bank 2: sr21 through sr28 sr31 through sr38 Bank 3: sr41 through sr48 sr51 through sr58 Bank 4: sr61 through sr68 sr71 through sr78   s: Mainframe slot number (1 through 8) r: 34945EXT remote module (1 through 8)	This is a required parameter

Remarks

• For channels that are configured for the pulsed drive mode (see ROUTe:CHANnel:DRIVe:PULSe[:MODE] command), this command will always return "0" indicating that the channels are not being driven. Note that previous pulsed operations will have completed before the ROUTe:CHANnel:DRIVe:STATe? query is evaluated.

• For channels that are configured for the non-verified, single-coil, non-pulsed drive mode (see ROUTe:CHANnel:VERify[:ENABle], ROUTe:CHANnel:DRIVe:PAIRed[:MODE], and ROUTe:CHANnel:DRIVe:PULSe[:MODE] commands), the ROUTe:CLOSe? command can also be used to accurately determine the current drive state.

Return Format

The command returns "1" if the specified channel is being driven or "0" if the specified channel is not being driven. Multiple responses are separated by commas.

Example

The following program segment queries the channel drive state for channels 01 through 05 on Bank 2 on 34945EXT remote module #2 (slot 3).

ROUT:RMOD:DRIV:SOUR OFF,(@3200)  !Must disable channel drive
ROUT:CHAN:DRIV:PAIR:MODE OFF,(@3201:3205)  !Disable paired-coil mode
ROUT:CHAN:DRIV:PULS:MODE OFF,(@3201:3205)  !Enable continuous mode
ROUT:CHAN:VER:ENAB ON,(@3201:3205)  !Enable verification
ROUT:RMOD:DRIV:SOUR EXT,(@3200)  !Enable channel drive
ROUT:CLOS (@3201:3205)  !Continuous drive close operation
ROUT:CHAN:DRIV:STAT? (@3201:3205)  !Query drive state

Typical Response:  1,1,1,1,1
