:EXTernal Trigger Commands
Control the input characteristics of the external trigger input. See
"Introduction to :EXTernal Trigger Commands" on page 263.
Introduction to
:EXTernal Trigger
Commands
The EXTernal trigger subsystem commands control the input
characteristics of the external trigger input. The probe factor, impedance,
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.
Return Format
The following is a sample response from the :EXTernal query. In this case,
the query was issued following a *RST command.
:EXT:BWL 0;RANG +8E+00;UNIT VOLT;PROB +1.000E+00
