:EXTernal:PROTection
Command Syntax
:EXTernal:PROTection[:CLEar]
When the external trigger input impedance is set to 50
Ω
(on the
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
Ω
. The
:EXTernal:PROTection[:CLEar] command is used to clear (reset) the
overload protection. It allows the external trigger to be used again in 50
Ω
mode after the signal that caused the overload has been removed from the
external trigger input. Reset the external trigger input impedance to 50
Ω
(see
on page 257) after clearing the overvoltage
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>
