Introduction to The EXTernal trigger subsystem commands control the input
:EXTernal Trigger
characteristics of the external trigger input. The probe factor, impedance,
Commands input range, input protection state, units, and bandwidth limit settings
may all be queried. Depending on the instrument type, some settings may
be changeable.
Reporting the Setup
Use :EXTernal? to query setup information for the EXTernal subsystem.
