The Analog Bus relays (numbered s921, s922, s923, etc.) on the matrix modules
are ignored if they are included in a range of channels. An error will be generated
if an Analog Bus relay is specified as the first or last channel in a range of
channels. For example, the following command closes all valid channels between
channel 304 and channel 615 (slot 2). In addition, this command closes Analog
Bus relay 911 on the module in slot 1 (Bank 1). Note that although the specified
range of channels includes the other Analog Bus relays, they are ignored and are
not closed by this command.
ROUTe:CLOSe (@2304:2615,1911)
Example: Querying channels for open or close state
The following
command returns a 1 (true) or 0 (false) state of channel 204 for a module in slot 3.
ROUTe:CLOSe (@3204)
ROUTe:CLOSe? (@3204) !Returns a 1
ROUTe:OPEN? (@3204) !Returns a 0
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
NOTE
When using a command to configure the system, the new configuration does not
take effect until you cycle power on the 34980A.
