*RST
Syntax
*RST
Description
This command resets the mainframe, internal DMM, and all installed modules to the Factory configuration. See Factory Reset State for a complete listing of the instrument's Factory configuration.
Remarks
This command does not affect any previously-stored instrument states (see *SAV command).
This command does not affect any previously-defined channel labels (see ROUTe:CHANnel:LABel[:DEFine] command).
On the 34945A Microwave Switch/Attenuator Driver, this command drives all channels on a remote module to their default switch states as specified by the ROUTe:CHANnel:DRIVe:OPEN:DEFault command and sets all channel drives to the specified boot state (see ROUTe:RMODule:DRIVe:SOURce:BOOT command). In addition, when the *RST command is executed, the 34945A automatically re-evaluates all external remote module connections to determine what is connected, what is powered, etc. No other settings are changed.
On the 34945A Microwave Switch/Attenuator Driver, the time required to complete a reset may be significant depending on the specified pulse width (see ROUTe:CHANnel:DRIVe:PULSe:WIDTh command) and power supply recovery time (see ROUTe:CHANnel:DRIVe:TIME:RECovery command). If both values are set to their upper limits (255 ms each) for all channels, the time required to reset (or boot) the module may exceed 30 seconds:
64 Channels x (255 ms Pulse Width + 255 ms Recovery Time) = ~33 seconds
Example
The following command resets the instrument.
