Remarks
This command does not reset the internal DMM.
To reset all eight slots in the instrument, send the *RST command.
This command may be used to restore normal operation to a 34925A FET Multiplexer that is in the overvoltage state.
On the 34945A Microwave Switch/Attenuator Driver, this command resets all channels on a remote module to their default 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). When the SYSTem:CPON command is executed, the 34945A does not re-evaluate the external remote module connections (unlike the *RST command which does a re-evaluation).
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 module installed in slot 3.
SYST:CPON 3
