M300 Programming Guide 2-101
Alarms/Ext Trig Interface
 BUS (Single): the instrument switches to the next channel when the *TRG command
is send via the remote interface. The
*TRG command is only valid when M300 is in the
"wait-for-trigger" state (refer to the
INITiate command).
The BUS trigger mode dose not support “BUS (Single)” advanced source.
 IMMediate: the instrument opens the current channel and closes the next channel
after finishing measuring the current channel.
 DIO and TOT channels do not support the advanced source setting. Measurements on
these channels can be performed by M300 alone and the signal synchronization with
the external multimeter is not required.
 The instrument selects external advanced souce after a Factory Reset (the
*RST
command) or when mainframe power is cycled (on the power-on value is set to
“Default”, refer to the
SYSTem:UTIlity:CONFigure:POWEron command). The current
settings will be not be affected after an Instrument Preset (the
SYSTem:PRESet
command).
