Alarm Output
When the Out check box is selected, you can output the alarm occurrence status as a
bus trigger to the measuring station’s BUSTRG1 or BUSTRG2.
An alarm is output if any of the groups for which alarm output was specified generate an
alarm.
When an alarm occurs and the bus trigger signals are set to output from the WE7231 in
the Trigger Source/Time Base Source/Arming settings dialog box, if the alarm output
conditions are Rise/Fall when the conditions are met, the bus trigger signal is set to True
for approximately 1
µ
s. When the alarm output conditions are High, Low, In, or Out, the
bus trigger signal is True for as long as the conditions are met. For information about the
settings in the Trigger Source/Time Base Source Setting dialog box, see section 4.6,
“Setting the Trigger Source/Time Base Source/Arming” in the WE7000 User’s Manual (IM
707001-01E).
