Configuring a Module
Example: Configuring the 34933A module for 2-wire or 1-wire mode The
following command configures a matrix module in slot 4 for 1-wire
measurements. Because you can configure only the 34933A (and the 34923A
and 34925A MUX modules) for either 2-wire or 1-wire mode, an error is
generated if you send this command to a slot that does not contain one of
those three modules. If you are using terminal blocks with the 34933A
module, be sure to use the corresponding 2-wire or 1-wire terminal block.
SYSTem:MODule:WIRE:MODE WIRE1,4
Example: Querying the system for module Identify The following command
returns the identity of the module installed in slot 7.
SYSTem:CTYPe? 7
Reading Cycle Count and Resetting Modules to Power-On State
Example: Reading the cycle count for a relay The following command returns
the cycle count on channels 304 and 308 for a matrix module in slot 3.
DIAGnostic:RELay:CYCLes? (@3304,3308)
Example: Resetting module(s) to power-on state The following command
resets a module in slot 4 to its power-on state.
SYSTem:CPON 4
NOTE
When using a command to configure the system, the new
configuration does not take effect until you cycle power on the
34980A.
NOTE
For the 34933A matrix module, the query response may include a
suffix to indicate a 1-wire configuration. For example, the response
for the 34933A will be either "34933A" (differential mode) or
"34933A-1W" (single-ended mode).
