*1.For the 4278A, no discrimination needs to be made between the EXT mode and the
BUS mode. On the other hand, for the 4288A, you must specify the EXT mode when
supplying a trigger from an external trigger terminal or handler interface or the BUS
mode when supplying a trigger through GPIB.

Operation of
*TRG
command
Generates a trigger when the trigger mode
is EXT.
Generates a trigger and reads out the
measurement result after the completion of
measurement when the trigger mode is
BUS.
