External:protection - Agilent Technologies InfiniiVision 7000A Series Programmer's Manual

:EXTernal:PROTection

Command Syntax
:EXTernal:PROTection[:CLEar]
When the external trigger input impedance is set to 50
2- channel, 300 MHz, 500 MHz, and 1 GHz bandwidth oscilloscope models),
the external trigger input is protected against overvoltage. When an
overvoltage condition is sensed, the input impedance for the external
trigger is automatically changed to 1 M
:EXTernal:PROTection[:CLEar] command is used to clear (reset) the
overload protection. It allows the external trigger to be used again in 50
mode after the signal that caused the overload has been removed from the
external trigger input. Reset the external trigger input impedance to 50
(see
protection.
Query Syntax
:EXTernal:PROTection?
The :EXTernal:PROTection query returns the state of the input protection
for external trigger. If the external trigger input has experienced an
overload, TRIP (tripped) will be returned; otherwise NORM (normal) is
returned.
Return Format
{NORM | TRIP}<NL>
