16 :EXTernal Trigger Commands
Control the input characteristics of the external trigger input. See "Introduction to
:EXTernal Trigger Commands" on page 339.
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 +8.0E+00;UNIT VOLT;PROB +1.000E+00
