SYSTem:MODule:WIRE:MODE
Syntax
SYSTem:MODule:WIRE:MODE <mode>, <slot>
Description
This command configures the module in the specified slot for 2-wire (differential) or 1-wire (single ended) measurements.
|
|
If you change the module configuration, you must cycle power on the 34980A to activate the new setting. |
Used With:
34923A Reed Multiplexer
34925A FET Multiplexer
34933A Dual 4x8 Reed Matrix

Remarks
This command applies only to those modules listed above. An error will be generated if you send this command to a slot that doesn't contain one of these modules.
This command does not have a query form. To determine whether the module is in the 2-wire or 1-wire configuration, send the SYSTem:CTYPe? or SYSTem:CDEScription? command after cycling power to the 34980A. For example, the SYSTem:CTYPe? response for the 34923A will be either "34923A" (differential mode) or "34923A-1W" (single-ended mode).
If you are using terminal blocks with these modules, be sure to use the corresponding 2-wire or 1-wire terminal block.

Description
34923T
– Option 001 40-Channel Reed Multiplexer (2-Wire Mode)
34923T
– Option 002 80-Channel Reed Multiplexer (1-Wire Mode)
34925T
– Option 001 40-Channel FET Multiplexer (2-Wire Mode)
34925T
– Option 002 80-Channel FET Multiplexer (1-Wire Mode)
34933T
– Option 001 Dual 4x8 Reed Matrix (2-Wire Mode)
34933T

The module configuration is stored in non-volatile memory on the module and does not change when you remove the module from the mainframe, after a Factory Reset (*RST command), or after an Instrument Preset (SYSTem:PRESet command).
Example
The following command selects the 1-wire configuration on the module in slot 3. Remember, the new configuration will not take effect until you cycle power on the 34980A.
