ROUTe:CHANnel:FWIRe

Syntax

ROUTe:CHANnel:FWIRe <state>[,(@<ch_list>)]

ROUTe:CHANnel:FWIRe? [(@<ch_list>)]

Description

This command configures the specified channels for 4-wire external scanning without the internal DMM. When enabled, channel n is paired with channel n+10 (34901A) or n+8 (34902A) to provide source and sense connections.

This command is valid only when the internal DMM is disabled (see INSTrument:DMM command) or removed from the Keysight 34970A/34972A.

Used With:

  • 34901A   20 Channel Multiplexer (2/4-wire) Module
  • 34902A   16 Channel Multiplexer (2/4-wire) Module

Parameters

Name Type Range of Values Default Value
<state> Boolean {OFF|0|ON|1}  
<ch_list> Channel List

One or more channels, as shown:

(@310) - channel 10 on the module in slot 300.

(@305:310) - channels 05 through 10 on the module in slot 300.

(@202:207,209,302:308) - channels 02 through 07 and 09 on the module in slot 200 and channels 02 through 08 on the module in slot 300.

If <ch_list> is omitted, this command applies to the current scan list.

Remarks

  • Specify the paired channel in Bank 1 (source) as the <ch_list> channel (channels in Bank 2 are not allowed in the <ch_list>).
  • The ROUTe:CLOSe, ROUTe:CLOSe:EXCLusive, and ROUTe:OPEN commands ignore the current ROUTe:CHANnel:FWIRe setting (if no channels are in the scan list).

Return Format

The query returns 0 (OFF) or 1 (ON) for each channel specified. Multiple responses are separated by commas.

Examples

The following command configures channels 03 and 05 in slot 100 for 4-wire external scanning.

INST:DMM OFF  !Disable internal DMM
ROUT:CHAN:FWIR ON,(@103,105) !Enable 4-wire configuration

 

The following query returns the 4-wire configuration selected on channels 03 and 05 in slot 100.

ROUT:CHAN:FWIR? (@103,105)

Typical Response: 1,1
