Commands by Subsystem
:CHANnel<n>:PROTection
Command Syntax
:CHANnel<n>:PROTection[:CLEar]
<n> ::= {1 | 2 | 3 | 4}
When the analog channel input impedance is set to 50
Ω
(on the 300 MHz,
500 MHz, and 1 GHz bandwidth oscilloscope models), the input channels
are protected against overvoltage. When an overvoltage condition is sensed,
the input impedance for the channel is automatically changed to 1 M
Ω
.
The :CHANnel<n>:PROTection[:CLEar] command is used to clear (reset) the
overload protection. It allows the channel to be used again in 50
Ω
mode
after the signal that caused the overload has been removed from the
channel input. Reset the analog channel input impedance to 50
Ω
(see
on page 223) after clearing the overvoltage
protection.
Query Syntax
:CHANnel<n>:PROTection?
The :CHANnel<n>:PROTection query returns the state of the input
protection for CHANnel<n>. If a channel input has experienced an
overload, TRIP (tripped) will be returned; otherwise NORM (normal) is
returned.
Return Format
{NORM | TRIP}<NL>
